## Instance Methods

Adds an access config to an instance's network interface.

Retrieves aggregated list of instances.

Retrieves the next page of results.

Attaches a Disk resource to an instance.

Deletes the specified Instance resource. For more information, see Stopping or Deleting an Instance.

Deletes an access config from an instance's network interface.

Detaches a disk from an instance.

Returns the specified Instance resource. Get a list of available instances by making a list() request.

Returns the specified instance's serial port output.

Creates an instance resource in the specified project using the data included in the request.

Retrieves the list of instances contained within the specified zone.

Retrieves the next page of results.

Performs a hard reset on the instance.

Sets the auto-delete flag for a disk attached to an instance.

Changes the machine type for a stopped instance to the machine type specified in the request.

Sets metadata for the specified instance to the data included in the request.

Sets an instance's scheduling options.

Sets tags for the specified instance to the data included in the request.

Starts an instance that was stopped using the using the instances().stop method. For more information, see Restart an instance.

Starts an instance that was stopped using the using the instances().stop method. For more information, see Restart an instance.

Stops a running instance, shutting it down cleanly, and allows you to restart the instance at a later time. Stopped instances do not incur per-minute, virtual machine usage charges while they are stopped, but any resources that the virtual machine is using, such as persistent disks and static IP addresses, will continue to be charged until they are deleted. For more information, see Stopping an instance.

### Method Details

`addAccessConfig(project, zone, instance, networkInterface, body)`

    Adds an access config to an instance's network interface.

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

    Retrieves aggregated list of instances.

    Args:
      project: string, Project ID for this request. (required)
      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.
      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.
      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.
      filter: string, Sets a filter expression for filtering listed resources, in the form filter={expression}. Your {expression} must be in the format: field_name comparison_string literal_string.

    The field_name is the name of the field you want to compare. Only atomic field types are supported (string, number, boolean). The comparison_string must be either eq (equals) or ne (not equals). The literal_string is the string value to filter to. The literal value must be valid for the type of field you are filtering by (string, number, boolean). For string fields, the literal value is interpreted as a regular expression using RE2 syntax. The literal value must match the entire field.

    For example, to filter for instances that do not have a name of example-instance, you would use filter=name ne example-instance.

    You can filter on nested fields. For example, you could filter on instances that have set the scheduling.automaticRestart field to true. Use filtering on nested fields to take advantage of labels to organize and search for results based on label values.

    To filter on multiple expressions, provide each separate expression within parentheses. For example, (scheduling.automaticRestart eq true) (zone eq us-central1-f). Multiple expressions are treated as AND expressions, meaning that resources must match all expressions to pass the filters.

    Returns:
      An object of the form:

        {
        "nextPageToken": "A String", # [Output Only] This token allows you to get the next page of results for list requests. If the number of results is larger than maxResults, use the nextPageToken as a value for the query parameter pageToken in the next list request. Subsequent list requests will have their own nextPageToken to continue paging through the results.

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

    Retrieves the list of instances contained within the specified zone.

    Args:
      project: string, Project ID for this request. (required)
      zone: string, The name of the zone for this request. (required)
      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.
      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.
      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.
      filter: string, Sets a filter expression for filtering listed resources, in the form filter={expression}. Your {expression} must be in the format: field_name comparison_string literal_string.

    The field_name is the name of the field you want to compare. Only atomic field types are supported (string, number, boolean). The comparison_string must be either eq (equals) or ne (not equals). The literal_string is the string value to filter to. The literal value must be valid for the type of field you are filtering by (string, number, boolean). For string fields, the literal value is interpreted as a regular expression using RE2 syntax. The literal value must match the entire field.

    For example, to filter for instances that do not have a name of example-instance, you would use filter=name ne example-instance.

    You can filter on nested fields. For example, you could filter on instances that have set the scheduling.automaticRestart field to true. Use filtering on nested fields to take advantage of labels to organize and search for results based on label values.

    To filter on multiple expressions, provide each separate expression within parentheses. For example, (scheduling.automaticRestart eq true) (zone eq us-central1-f). Multiple expressions are treated as AND expressions, meaning that resources must match all expressions to pass the filters.

    Returns:
      An object of the form:

        { # Contains a list of instances.
        "nextPageToken": "A String", # [Output Only] This token allows you to get the next page of results for list requests. If the number of results is larger than maxResults, use the nextPageToken as a value for the query parameter pageToken in the next list request. Subsequent list requests will have their own nextPageToken to continue paging through the results.
