## Instance Methods

Flags the specified instances to be removed from the managed instance group. Abandoning an instance does not delete the instance, but it does remove the instance from any target pools that are applied by the managed instance group. This method reduces the targetSize of the managed instance group by the number of instances that you abandon. This operation is marked as DONE when the action is scheduled even if the instances have not yet been removed from the group. You must separately verify the status of the abandoning action with the listmanagedinstances method. If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is removed or deleted. You can specify a maximum of 1000 instances with this method per request.

Retrieves the list of managed instance groups and groups them by zone.

Applies changes to selected instances on the managed instance group. This method can be used to apply new overrides and/or new versions.

Close httplib2 connections.

Creates instances with per-instance configurations in this managed instance group. Instances are created using the current instance template. The create instances operation is marked DONE if the createInstances request is successful. The underlying actions take additional time. You must separately verify the status of the creating or actions with the listmanagedinstances method.

Deletes the specified managed instance group and all of the instances in that group. Note that the instance group must not belong to a backend service. Read Deleting an instance group for more information.

Flags the specified instances in the managed instance group for immediate deletion. The instances are also removed from any target pools of which they were a member. This method reduces the targetSize of the managed instance group by the number of instances that you delete. This operation is marked as DONE when the action is scheduled even if the instances are still being deleted. You must separately verify the status of the deleting action with the listmanagedinstances method. If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is removed or deleted. You can specify a maximum of 1000 instances with this method per request.

Deletes selected per-instance configurations for the managed instance group.

Returns all of the details about the specified managed instance group. Gets a list of available managed instance groups by making a list() request.

Creates a managed instance group using the information that you specify in the request. After the group is created, instances in the group are created using the specified instance template. This operation is marked as DONE when the group is created even if the instances in the group have not yet been created. You must separately verify the status of the individual instances with the listmanagedinstances method. A managed instance group can have up to 1000 VM instances per group. Please contact Cloud Support if you need an increase in this limit.

Retrieves a list of managed instance groups that are contained within the specified project and zone.

Lists all errors thrown by actions on instances for a given managed instance group. The filter and orderBy query parameters are not supported.

Retrieves the next page of results.

Lists all of the instances in the managed instance group. Each instance in the list has a currentAction, which indicates the action that the managed instance group is performing on the instance. For example, if the group is still creating an instance, the currentAction is CREATING. If a previous action failed, the list displays the errors for that failed action. The orderBy query parameter is not supported. The `pageToken` query parameter is supported only in the alpha and beta API and only if the group's `listManagedInstancesResults` field is set to `PAGINATED`.

Retrieves the next page of results.

Lists all of the per-instance configurations defined for the managed instance group. The orderBy query parameter is not supported.

Updates a managed instance group using the information that you specify in the request. This operation is marked as DONE when the group is patched even if the instances in the group are still in the process of being patched. You must separately verify the status of the individual instances with the listManagedInstances method. This method supports PATCH semantics and uses the JSON merge patch format and processing rules. If you update your group to specify a new template or instance configuration, it's possible that your intended specification for each VM in the group is different from the current state of that VM. To learn how to apply an updated configuration to the VMs in a MIG, see Updating instances in a MIG.

Inserts or patches per-instance configurations for the managed instance group. perInstanceConfig.name serves as a key used to distinguish whether to perform insert or patch.

Flags the specified VM instances in the managed instance group to be immediately recreated. Each instance is recreated using the group's current configuration. This operation is marked as DONE when the flag is set even if the instances have not yet been recreated. You must separately verify the status of each instance by checking its currentAction field; for more information, see Checking the status of managed instances. If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is removed or deleted. You can specify a maximum of 1000 instances with this method per request.

Resizes the managed instance group. If you increase the size, the group creates new instances using the current instance template. If you decrease the size, the group deletes instances. The resize operation is marked DONE when the resize actions are scheduled even if the group has not yet added or deleted any instances. You must separately verify the status of the creating or deleting actions with the listmanagedinstances method. When resizing down, the instance group arbitrarily chooses the order in which VMs are deleted. The group takes into account some VM attributes when making the selection including: + The status of the VM instance. + The health of the VM instance. + The instance template version the VM is based on. + For regional managed instance groups, the location of the VM instance. This list is subject to change. If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is removed or deleted.

Resizes the managed instance group with advanced configuration options like disabling creation retries. This is an extended version of the resize method. If you increase the size of the instance group, the group creates new instances using the current instance template. If you decrease the size, the group deletes instances. The resize operation is marked DONE when the resize actions are scheduled even if the group has not yet added or deleted any instances. You must separately verify the status of the creating, creatingWithoutRetries, or deleting actions with the get or listmanagedinstances method. If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is removed or deleted.

Flags the specified instances in the managed instance group to be resumed. This method increases the targetSize and decreases the targetSuspendedSize of the managed instance group by the number of instances that you resume. The resumeInstances operation is marked DONE if the resumeInstances request is successful. The underlying actions take additional time. You must separately verify the status of the RESUMING action with the listmanagedinstances method. In this request, you can only specify instances that are suspended. For example, if an instance was previously suspended using the suspendInstances method, it can be resumed using the resumeInstances method. If a health check is attached to the managed instance group, the specified instances will be verified as healthy after they are resumed. You can specify a maximum of 1000 instances with this method per request.

Motifies the autohealing policy for the instances in this managed instance group. [Deprecated] This method is deprecated. Use instanceGroupManagers.patch instead.

Specifies the instance template to use when creating new instances in this group. The templates for existing instances in the group do not change unless you run recreateInstances, run applyUpdatesToInstances, or set the group's updatePolicy.type to PROACTIVE.

Modifies the target pools to which all instances in this managed instance group are assigned. The target pools automatically apply to all of the instances in the managed instance group. This operation is marked DONE when you make the request even if the instances have not yet been added to their target pools. The change might take some time to apply to all of the instances in the group depending on the size of the group.

Flags the specified instances in the managed instance group to be started. This method increases the targetSize and decreases the targetStoppedSize of the managed instance group by the number of instances that you start. The startInstances operation is marked DONE if the startInstances request is successful. The underlying actions take additional time. You must separately verify the status of the STARTING action with the listmanagedinstances method. In this request, you can only specify instances that are stopped. For example, if an instance was previously stopped using the stopInstances method, it can be started using the startInstances method. If a health check is attached to the managed instance group, the specified instances will be verified as healthy after they are started. You can specify a maximum of 1000 instances with this method per request.

Flags the specified instances in the managed instance group to be immediately stopped. You can only specify instances that are running in this request. This method reduces the targetSize and increases the targetStoppedSize of the managed instance group by the number of instances that you stop. The stopInstances operation is marked DONE if the stopInstances request is successful. The underlying actions take additional time. You must separately verify the status of the STOPPING action with the listmanagedinstances method. If the standbyPolicy.initialDelaySec field is set, the group delays stopping the instances until initialDelaySec have passed from instance.creationTimestamp (that is, when the instance was created). This delay gives your application time to set itself up and initialize on the instance. If more than initialDelaySec seconds have passed since instance.creationTimestamp when this method is called, there will be zero delay. If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is stopped. Stopped instances can be started using the startInstances method. You can specify a maximum of 1000 instances with this method per request.

Flags the specified instances in the managed instance group to be immediately suspended. You can only specify instances that are running in this request. This method reduces the targetSize and increases the targetSuspendedSize of the managed instance group by the number of instances that you suspend. The suspendInstances operation is marked DONE if the suspendInstances request is successful. The underlying actions take additional time. You must separately verify the status of the SUSPENDING action with the listmanagedinstances method. If the standbyPolicy.initialDelaySec field is set, the group delays suspension of the instances until initialDelaySec have passed from instance.creationTimestamp (that is, when the instance was created). This delay gives your application time to set itself up and initialize on the instance. If more than initialDelaySec seconds have passed since instance.creationTimestamp when this method is called, there will be zero delay. If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is suspended. Suspended instances can be resumed using the resumeInstances method. You can specify a maximum of 1000 instances with this method per request.

Returns permissions that a caller has on the specified resource.

Updates a managed instance group using the information that you specify in the request. This operation is marked as DONE when the group is updated even if the instances in the group have not yet been updated. You must separately verify the status of the individual instances with the listManagedInstances method. If you update your group to specify a new template or instance configuration, it's possible that your intended specification for each VM in the group is different from the current state of that VM. To learn how to apply an updated configuration to the VMs in a MIG, see Updating instances in a MIG.

Inserts or updates per-instance configurations for the managed instance group. perInstanceConfig.name serves as a key used to distinguish whether to perform insert or patch.

### Method Details

`abandonInstances(project, zone, instanceGroupManager, body=None, requestId=None, x__xgafv=None)`

    Flags the specified instances to be removed from the managed instance group. Abandoning an instance does not delete the instance, but it does remove the instance from any target pools that are applied by the managed instance group. This method reduces the targetSize of the managed instance group by the number of instances that you abandon. This operation is marked as DONE when the action is scheduled even if the instances have not yet been removed from the group. You must separately verify the status of the abandoning action with the listmanagedinstances method. If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is removed or deleted. You can specify a maximum of 1000 instances with this method per request.

    Args:
      project: string, Project ID for this request. (required)
      zone: string, The name of the zone where the managed instance group is located. (required)
      instanceGroupManager: string, The name of the managed instance group. (required)
      body: object, The request body.
        The object takes the form of:

    {
      "instances": [ # The URLs of one or more instances to abandon. This can be a full URL or a partial URL, such as zones/[ZONE]/instances/[INSTANCE_NAME].
        "A String",
      ],
    }

      requestId: string, An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported ( 00000000-0000-0000-0000-000000000000).
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

`aggregatedList(project, filter=None, includeAllScopes=None, maxResults=None, orderBy=None, pageToken=None, returnPartialSuccess=None, x__xgafv=None)`

    Retrieves the list of managed instance groups and groups them by zone.

    Args:
      project: string, Project ID for this request. (required)
      filter: string, A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:` operator can be used with string fields to match substrings. For non-string fields it is equivalent to the `=` operator. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`.
      includeAllScopes: boolean, Indicates whether every visible scope for each scope type (zone, region, global) should be included in the response. For new resource types added after this field, the flag has no effect as new resource types will always include every visible scope for each scope type in response. For resource types which predate this field, if this flag is omitted or false, only scopes of the scope types where the resource type is expected to be found will be included.
      maxResults: integer, The maximum number of results per page that should be returned. If the number of available results is larger than `maxResults`, Compute Engine returns a `nextPageToken` that can be used to get the next page of results in subsequent list requests. Acceptable values are `0` to `500`, inclusive. (Default: `500`)
      orderBy: string, Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name. You can also sort results in descending order based on the creation timestamp using `orderBy="creationTimestamp desc"`. This sorts results based on the `creationTimestamp` field in reverse chronological order (newest result first). Use this to sort resources like operations so that the newest operation is returned first. Currently, only sorting by `name` or `creationTimestamp desc` is supported.
      pageToken: string, Specifies a page token to use. Set `pageToken` to the `nextPageToken` returned by a previous list request to get the next page of results.
      returnPartialSuccess: boolean, Opt-in for partial success behavior which provides partial results in case of failure. The default value is false.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:

      requestId: string, An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. The request ID must be a valid UUID with the exception that zero UUID is not supported ( 00000000-0000-0000-0000-000000000000).

`delete(project, zone, instanceGroupManager, requestId=None, x__xgafv=None)`

    Deletes the specified managed instance group and all of the instances in that group. Note that the instance group must not belong to a backend service. Read Deleting an instance group for more information.

    Args:
      project: string, Project ID for this request. (required)
      zone: string, The name of the zone where the managed instance group is located. (required)
      instanceGroupManager: string, The name of the managed instance group to delete. (required)
      requestId: string, An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported ( 00000000-0000-0000-0000-000000000000).
      x__xgafv: string, V1 error format.

`deleteInstances(project, zone, instanceGroupManager, body=None, requestId=None, x__xgafv=None)`

    Flags the specified instances in the managed instance group for immediate deletion. The instances are also removed from any target pools of which they were a member. This method reduces the targetSize of the managed instance group by the number of instances that you delete. This operation is marked as DONE when the action is scheduled even if the instances are still being deleted. You must separately verify the status of the deleting action with the listmanagedinstances method. If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is removed or deleted. You can specify a maximum of 1000 instances with this method per request.

    Args:
      project: string, Project ID for this request. (required)
      zone: string, The name of the zone where the managed instance group is located. (required)
      instanceGroupManager: string, The name of the managed instance group. (required)
      body: object, The request body.
        The object takes the form of:

    {
      "instances": [ # The URLs of one or more instances to delete. This can be a full URL or a partial URL, such as zones/[ZONE]/instances/[INSTANCE_NAME].
        "A String",
      ],
      "skipInstancesOnValidationError": True or False, # Specifies whether the request should proceed despite the inclusion of instances that are not members of the group or that are already in the process of being deleted or abandoned. If this field is set to `false` and such an instance is specified in the request, the operation fails. The operation always fails if the request contains a malformed instance URL or a reference to an instance that exists in a zone or region other than the group's zone or region.

    Creates a managed instance group using the information that you specify in the request. After the group is created, instances in the group are created using the specified instance template. This operation is marked as DONE when the group is created even if the instances in the group have not yet been created. You must separately verify the status of the individual instances with the listmanagedinstances method. A managed instance group can have up to 1000 VM instances per group. Please contact Cloud Support if you need an increase in this limit.

`list(project, zone, filter=None, maxResults=None, orderBy=None, pageToken=None, returnPartialSuccess=None, x__xgafv=None)`

    Retrieves a list of managed instance groups that are contained within the specified project and zone.

    Args:
      project: string, Project ID for this request. (required)
      zone: string, The name of the zone where the managed instance group is located. (required)
      filter: string, A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:` operator can be used with string fields to match substrings. For non-string fields it is equivalent to the `=` operator. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`.
      maxResults: integer, The maximum number of results per page that should be returned. If the number of available results is larger than `maxResults`, Compute Engine returns a `nextPageToken` that can be used to get the next page of results in subsequent list requests. Acceptable values are `0` to `500`, inclusive. (Default: `500`)
      orderBy: string, Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name. You can also sort results in descending order based on the creation timestamp using `orderBy="creationTimestamp desc"`. This sorts results based on the `creationTimestamp` field in reverse chronological order (newest result first). Use this to sort resources like operations so that the newest operation is returned first. Currently, only sorting by `name` or `creationTimestamp desc` is supported.
      pageToken: string, Specifies a page token to use. Set `pageToken` to the `nextPageToken` returned by a previous list request to get the next page of results.
      returnPartialSuccess: boolean, Opt-in for partial success behavior which provides partial results in case of failure. The default value is false.
      x__xgafv: string, V1 error format.

For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:` operator can be used with string fields to match substrings. For non-string fields it is equivalent to the `=` operator. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`.
      maxResults: integer, The maximum number of results per page that should be returned. If the number of available results is larger than `maxResults`, Compute Engine returns a `nextPageToken` that can be used to get the next page of results in subsequent list requests. Acceptable values are `0` to `500`, inclusive. (Default: `500`)
      orderBy: string, Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name. You can also sort results in descending order based on the creation timestamp using `orderBy="creationTimestamp desc"`. This sorts results based on the `creationTimestamp` field in reverse chronological order (newest result first). Use this to sort resources like operations so that the newest operation is returned first. Currently, only sorting by `name` or `creationTimestamp desc` is supported.
      pageToken: string, Specifies a page token to use. Set `pageToken` to the `nextPageToken` returned by a previous list request to get the next page of results.
      returnPartialSuccess: boolean, Opt-in for partial success behavior which provides partial results in case of failure. The default value is false.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

`listErrors_next()`

    Retrieves the next page of results.

            Args:
              previous_request: The request for the previous page. (required)
              previous_response: The response from the request for the previous page. (required)

`listManagedInstances(project, zone, instanceGroupManager, filter=None, maxResults=None, orderBy=None, pageToken=None, returnPartialSuccess=None, x__xgafv=None)`

    Lists all of the instances in the managed instance group. Each instance in the list has a currentAction, which indicates the action that the managed instance group is performing on the instance. For example, if the group is still creating an instance, the currentAction is CREATING. If a previous action failed, the list displays the errors for that failed action. The orderBy query parameter is not supported. The `pageToken` query parameter is supported only in the alpha and beta API and only if the group's `listManagedInstancesResults` field is set to `PAGINATED`.

    Args:
      project: string, Project ID for this request. (required)
      zone: string, The name of the zone where the managed instance group is located. (required)
      instanceGroupManager: string, The name of the managed instance group. (required)
      filter: string, A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean.

      filter: string, A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:` operator can be used with string fields to match substrings. For non-string fields it is equivalent to the `=` operator. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`.
      maxResults: integer, The maximum number of results per page that should be returned. If the number of available results is larger than `maxResults`, Compute Engine returns a `nextPageToken` that can be used to get the next page of results in subsequent list requests. Acceptable values are `0` to `500`, inclusive. (Default: `500`)
      orderBy: string, Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name. You can also sort results in descending order based on the creation timestamp using `orderBy="creationTimestamp desc"`. This sorts results based on the `creationTimestamp` field in reverse chronological order (newest result first). Use this to sort resources like operations so that the newest operation is returned first. Currently, only sorting by `name` or `creationTimestamp desc` is supported.
      pageToken: string, Specifies a page token to use. Set `pageToken` to the `nextPageToken` returned by a previous list request to get the next page of results.
      returnPartialSuccess: boolean, Opt-in for partial success behavior which provides partial results in case of failure. The default value is false.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

`patch(project, zone, instanceGroupManager, body=None, requestId=None, x__xgafv=None)`

    Updates a managed instance group using the information that you specify in the request. This operation is marked as DONE when the group is patched even if the instances in the group are still in the process of being patched. You must separately verify the status of the individual instances with the listManagedInstances method. This method supports PATCH semantics and uses the JSON merge patch format and processing rules. If you update your group to specify a new template or instance configuration, it's possible that your intended specification for each VM in the group is different from the current state of that VM. To learn how to apply an updated configuration to the VMs in a MIG, see Updating instances in a MIG.

    Args:
      project: string, Project ID for this request. (required)
      zone: string, The name of the zone where you want to create the managed instance group. (required)
      instanceGroupManager: string, The name of the instance group manager. (required)
      body: object, The request body.
        The object takes the form of:

For zonal Managed Instance Group, use the instanceGroupManagers resource. For regional Managed Instance Group, use the regionInstanceGroupManagers resource.
      "allInstancesConfig": { # Specifies configuration that overrides the instance template configuration for the group.
        "properties": { # Represents the change that you want to make to the instance properties. # Properties to set on all instances in the group. You can add or modify properties using the instanceGroupManagers.patch or regionInstanceGroupManagers.patch. After setting allInstancesConfig on the group, you must update the group's instances to apply the configuration. To apply the configuration, set the group's updatePolicy.type field to use proactive updates or use the applyUpdatesToInstances method.

Instance's currentAction is NONE (in particular its liveness health check result was observed to be HEALTHY at least once as it passed VERIFYING). 3. There is no outgoing action on an instance triggered by IGM. By default, number of concurrently autohealed instances is smaller than the managed instance group target size. However, if a zonal managed instance group has only one instance, or a regional managed instance group has only one instance per zone, autohealing will recreate these instances when they become unhealthy.

      requestId: string, An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported ( 00000000-0000-0000-0000-000000000000).

`recreateInstances(project, zone, instanceGroupManager, body=None, requestId=None, x__xgafv=None)`

    Flags the specified VM instances in the managed instance group to be immediately recreated. Each instance is recreated using the group's current configuration. This operation is marked as DONE when the flag is set even if the instances have not yet been recreated. You must separately verify the status of each instance by checking its currentAction field; for more information, see Checking the status of managed instances. If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is removed or deleted. You can specify a maximum of 1000 instances with this method per request.

    Args:
      project: string, Project ID for this request. (required)
      zone: string, The name of the zone where the managed instance group is located. (required)
      instanceGroupManager: string, The name of the managed instance group. (required)
      body: object, The request body.
        The object takes the form of:

    {
      "instances": [ # The URLs of one or more instances to recreate. This can be a full URL or a partial URL, such as zones/[ZONE]/instances/[INSTANCE_NAME].
        "A String",
      ],
    }

      requestId: string, An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported ( 00000000-0000-0000-0000-000000000000).

`resize(project, zone, instanceGroupManager, size, requestId=None, x__xgafv=None)`

    Resizes the managed instance group. If you increase the size, the group creates new instances using the current instance template. If you decrease the size, the group deletes instances. The resize operation is marked DONE when the resize actions are scheduled even if the group has not yet added or deleted any instances. You must separately verify the status of the creating or deleting actions with the listmanagedinstances method. When resizing down, the instance group arbitrarily chooses the order in which VMs are deleted. The group takes into account some VM attributes when making the selection including: + The status of the VM instance. + The health of the VM instance. + The instance template version the VM is based on. + For regional managed instance groups, the location of the VM instance. This list is subject to change. If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is removed or deleted.

    Args:
      project: string, Project ID for this request. (required)
      zone: string, The name of the zone where the managed instance group is located. (required)
      instanceGroupManager: string, The name of the managed instance group. (required)
      size: integer, The number of running instances that the managed instance group should maintain at any given time. The group automatically adds or removes instances to maintain the number of instances specified by this parameter. (required)

`resizeAdvanced(project, zone, instanceGroupManager, body=None, requestId=None, x__xgafv=None)`

    Resizes the managed instance group with advanced configuration options like disabling creation retries. This is an extended version of the resize method. If you increase the size of the instance group, the group creates new instances using the current instance template. If you decrease the size, the group deletes instances. The resize operation is marked DONE when the resize actions are scheduled even if the group has not yet added or deleted any instances. You must separately verify the status of the creating, creatingWithoutRetries, or deleting actions with the get or listmanagedinstances method. If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is removed or deleted.

    Args:
      project: string, Project ID for this request. (required)
      zone: string, The name of the zone where the managed instance group is located. (required)
      instanceGroupManager: string, The name of the managed instance group. (required)
      body: object, The request body.
        The object takes the form of:

    {
      "noCreationRetries": True or False, # If this flag is true, the managed instance group attempts to create all instances initiated by this resize request only once. If there is an error during creation, the managed instance group does not retry create this instance, and we will decrease the targetSize of the request instead. If the flag is false, the group attempts to recreate each instance continuously until it succeeds. This flag matters only in the first attempt of creation of an instance. After an instance is successfully created while this flag is enabled, the instance behaves the same way as all the other instances created with a regular resize request. In particular, if a running instance dies unexpectedly at a later time and needs to be recreated, this mode does not affect the recreation behavior in that scenario. This flag is applicable only to the current resize request. It does not influence other resize requests in any way. You can see which instances is being creating in which mode by calling the get or listManagedInstances API.
      "targetSize": 42, # The number of running instances that the managed instance group should maintain at any given time. The group automatically adds or removes instances to maintain the number of instances specified by this parameter.
    }

      requestId: string, An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported ( 00000000-0000-0000-0000-000000000000).
      x__xgafv: string, V1 error format.

`resumeInstances(project, zone, instanceGroupManager, body=None, requestId=None, x__xgafv=None)`

    Flags the specified instances in the managed instance group to be resumed. This method increases the targetSize and decreases the targetSuspendedSize of the managed instance group by the number of instances that you resume. The resumeInstances operation is marked DONE if the resumeInstances request is successful. The underlying actions take additional time. You must separately verify the status of the RESUMING action with the listmanagedinstances method. In this request, you can only specify instances that are suspended. For example, if an instance was previously suspended using the suspendInstances method, it can be resumed using the resumeInstances method. If a health check is attached to the managed instance group, the specified instances will be verified as healthy after they are resumed. You can specify a maximum of 1000 instances with this method per request.

    Args:
      project: string, Project ID for this request. (required)
      zone: string, The name of the zone where the managed instance group is located. (required)
      instanceGroupManager: string, The name of the managed instance group. (required)
      body: object, The request body.
        The object takes the form of:

`setAutoHealingPolicies(project, zone, instanceGroupManager, body=None, requestId=None, x__xgafv=None)`

    Motifies the autohealing policy for the instances in this managed instance group. [Deprecated] This method is deprecated. Use instanceGroupManagers.patch instead.

    Args:
      project: string, Project ID for this request. (required)
      zone: string, The name of the zone where the managed instance group is located. (required)
      instanceGroupManager: string, The name of the instance group manager. (required)
      body: object, The request body.
        The object takes the form of:

    {
      "autoHealingPolicies": [
        {
          "autoHealingTriggers": { # Restricts what triggers autohealing.
            "onHealthCheck": "A String", # If you have configured an application-based health check for the group, this field controls whether to trigger VM autohealing based on a failed health check. Valid values are: - ON (default): The group recreates running VMs that fail the application-based health check. - OFF: When set to OFF, you can still observe instance health state, but the group does not recreate VMs that fail the application-based health check. This is useful for troubleshooting and setting up your health check configuration.
          },
          "healthCheck": "A String", # The URL for the health check that signals autohealing.
          "initialDelaySec": 42, # The number of seconds that the managed instance group waits before it applies autohealing policies to new instances or recently recreated instances. This initial delay allows instances to initialize and run their startup scripts before the instance group determines that they are UNHEALTHY. This prevents the managed instance group from recreating its instances prematurely. This value must be from range [0, 3600].
          "maxUnavailable": { # Encapsulates numeric value that can be either absolute or relative. # Maximum number of instances that can be unavailable when autohealing. When 'percent' is used, the value is rounded if necessary. The instance is considered available if all of the following conditions are satisfied: 1. Instance's status is RUNNING. 2. Instance's currentAction is NONE (in particular its liveness health check result was observed to be HEALTHY at least once as it passed VERIFYING). 3. There is no outgoing action on an instance triggered by IGM. By default, number of concurrently autohealed instances is smaller than the managed instance group target size. However, if a zonal managed instance group has only one instance, or a regional managed instance group has only one instance per zone, autohealing will recreate these instances when they become unhealthy.
            "calculated": 42, # [Output Only] Absolute value of VM instances calculated based on the specific mode. - If the value is fixed, then the calculated value is equal to the fixed value. - If the value is a percent, then the calculated value is percent/100 * targetSize. For example, the calculated value of a 80% of a managed instance group with 150 instances would be (80/100 * 150) = 120 VM instances. If there is a remainder, the number is rounded.
            "fixed": 42, # Specifies a fixed number of VM instances. This must be a positive integer.
            "percent": 42, # Specifies a percentage of instances between 0 to 100%, inclusive. For example, specify 80 for 80%.
          },
        },
      ],
    }

      requestId: string, An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported ( 00000000-0000-0000-0000-000000000000).

`setTargetPools(project, zone, instanceGroupManager, body=None, requestId=None, x__xgafv=None)`

    Modifies the target pools to which all instances in this managed instance group are assigned. The target pools automatically apply to all of the instances in the managed instance group. This operation is marked DONE when you make the request even if the instances have not yet been added to their target pools. The change might take some time to apply to all of the instances in the group depending on the size of the group.

    Args:
      project: string, Project ID for this request. (required)
      zone: string, The name of the zone where the managed instance group is located. (required)
      instanceGroupManager: string, The name of the managed instance group. (required)
      body: object, The request body.
        The object takes the form of:

    {
      "fingerprint": "A String", # The fingerprint of the target pools information. Use this optional property to prevent conflicts when multiple users change the target pools settings concurrently. Obtain the fingerprint with the instanceGroupManagers.get method. Then, include the fingerprint in your request to ensure that you do not overwrite changes that were applied from another concurrent request.
      "targetPools": [ # The list of target pool URLs that instances in this managed instance group belong to. The managed instance group applies these target pools to all of the instances in the group. Existing instances and new instances in the group all receive these target pool settings.
        "A String",
      ],
    }

      requestId: string, An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported ( 00000000-0000-0000-0000-000000000000).
      x__xgafv: string, V1 error format.

`startInstances(project, zone, instanceGroupManager, body=None, requestId=None, x__xgafv=None)`

    Flags the specified instances in the managed instance group to be started. This method increases the targetSize and decreases the targetStoppedSize of the managed instance group by the number of instances that you start. The startInstances operation is marked DONE if the startInstances request is successful. The underlying actions take additional time. You must separately verify the status of the STARTING action with the listmanagedinstances method. In this request, you can only specify instances that are stopped. For example, if an instance was previously stopped using the stopInstances method, it can be started using the startInstances method. If a health check is attached to the managed instance group, the specified instances will be verified as healthy after they are started. You can specify a maximum of 1000 instances with this method per request.

    Args:
      project: string, Project ID for this request. (required)
      zone: string, The name of the zone where the managed instance group is located. (required)

`stopInstances(project, zone, instanceGroupManager, body=None, requestId=None, x__xgafv=None)`

    Flags the specified instances in the managed instance group to be immediately stopped. You can only specify instances that are running in this request. This method reduces the targetSize and increases the targetStoppedSize of the managed instance group by the number of instances that you stop. The stopInstances operation is marked DONE if the stopInstances request is successful. The underlying actions take additional time. You must separately verify the status of the STOPPING action with the listmanagedinstances method. If the standbyPolicy.initialDelaySec field is set, the group delays stopping the instances until initialDelaySec have passed from instance.creationTimestamp (that is, when the instance was created). This delay gives your application time to set itself up and initialize on the instance. If more than initialDelaySec seconds have passed since instance.creationTimestamp when this method is called, there will be zero delay. If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is stopped. Stopped instances can be started using the startInstances method. You can specify a maximum of 1000 instances with this method per request.

    Args:
      project: string, Project ID for this request. (required)
      zone: string, The name of the zone where the managed instance group is located. (required)
      instanceGroupManager: string, The name of the managed instance group. (required)
      body: object, The request body.
        The object takes the form of:

    {
      "forceStop": True or False, # If this flag is set to true, the Instance Group Manager will proceed to stop the instances, skipping initialization on them.
      "instances": [ # The URLs of one or more instances to stop. This can be a full URL or a partial URL, such as zones/[ZONE]/instances/[INSTANCE_NAME].
        "A String",
      ],
    }

      requestId: string, An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported ( 00000000-0000-0000-0000-000000000000).
      x__xgafv: string, V1 error format.

`update(project, zone, instanceGroupManager, body=None, requestId=None, x__xgafv=None)`

    Updates a managed instance group using the information that you specify in the request. This operation is marked as DONE when the group is updated even if the instances in the group have not yet been updated. You must separately verify the status of the individual instances with the listManagedInstances method. If you update your group to specify a new template or instance configuration, it's possible that your intended specification for each VM in the group is different from the current state of that VM. To learn how to apply an updated configuration to the VMs in a MIG, see Updating instances in a MIG.

      requestId: string, An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported ( 00000000-0000-0000-0000-000000000000).

      "user": "A String", # [Output Only] User who requested the operation, for example: `user@example.com`.
      "warnings": [ # [Output Only] If warning messages are generated during processing of the operation, this field will be populated.
        {
          "code": "A String", # [Output Only] A warning code, if applicable. For example, Compute Engine returns NO_RESULTS_ON_PAGE if there are no results in the response.
          "data": [ # [Output Only] Metadata about this warning in key: value format. For example: "data": [ { "key": "scope", "value": "zones/us-east1-d" }
            {
              "key": "A String", # [Output Only] A key that provides more detail on the warning being returned. For example, for warnings where there are no results in a list request for a particular zone, this key might be scope and the key value might be the zone name. Other examples might be a key indicating a deprecated resource and a suggested replacement, or a warning about invalid network settings (for example, if an instance attempts to perform IP forwarding but is not enabled for IP forwarding).
              "value": "A String", # [Output Only] A warning data value corresponding to the key.
