# Compute Engine API . instanceTemplates

## Instance Methods

Deletes the specified instance template. Deleting an instance template is permanent and cannot be undone. It is not possible to delete templates that are already in use by a managed instance group.

Returns the specified instance template. Gets a list of available instance templates by making a list() request.

Gets the access control policy for a resource. May be empty if no such policy or resource exists.

Creates an instance template in the specified project using the data that is included in the request. If you are creating a new template to update an existing instance group, your new instance template must use the same network or, if applicable, the same subnetwork as the original template.

Retrieves a list of instance templates that are contained within the specified project.

Retrieves the next page of results.

Sets the access control policy on the specified resource. Replaces any existing policy.

Returns permissions that a caller has on the specified resource.

### Method Details

`delete(project, instanceTemplate, requestId=None)`

    Deletes the specified instance template. Deleting an instance template is permanent and cannot be undone. It is not possible to delete templates that are already in use by a managed instance group.

    Args:
      project: string, Project ID for this request. (required)
      instanceTemplate: string, The name of the instance template 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).

    Returns:
      An object of the form:

`getIamPolicy(project, resource, optionsRequestedPolicyVersion=None)`

    Gets the access control policy for a resource. May be empty if no such policy or resource exists.

    Args:
      project: string, Project ID for this request. (required)
      resource: string, Name or id of the resource for this request. (required)
      optionsRequestedPolicyVersion: integer, Requested IAM Policy version.

    Returns:
      An object of the form:

          #
          #
          #
          # A `Policy` is a collection of `bindings`. A `binding` binds one or more `members` to a single `role`. Members can be user accounts, service accounts, Google groups, and domains (such as G Suite). A `role` is a named list of permissions; each `role` can be an IAM predefined role or a user-created custom role.
          #
          # For some types of Google Cloud resources, a `binding` can also specify a `condition`, which is a logical expression that allows access to a resource only if the expression evaluates to `true`. A condition can add constraints based on attributes of the request, the resource, or both. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies).

      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).

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

    Retrieves a list of instance templates that are contained within the specified project.

    Args:
      project: string, Project ID for this request. (required)
      filter: string, A filter expression that filters resources listed in the response. The expression must specify the field name, a comparison operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The comparison 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`.

    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) ```
      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 and the logic is the same as today.

    Returns:

          # A `Policy` is a collection of `bindings`. A `binding` binds one or more `members` to a single `role`. Members can be user accounts, service accounts, Google groups, and domains (such as G Suite). A `role` is a named list of permissions; each `role` can be an IAM predefined role or a user-created custom role.
          #
          # For some types of Google Cloud resources, a `binding` can also specify a `condition`, which is a logical expression that allows access to a resource only if the expression evaluates to `true`. A condition can add constraints based on attributes of the request, the resource, or both. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies).

            # **Important:** If you use IAM Conditions, you must include the `etag` field whenever you call `setIamPolicy`. If you omit this field, then IAM allows you to overwrite a version `3` policy with a version `1` policy, and all of the conditions in the version `3` policy are lost.
            #
            # If a policy does not include any conditions, operations on that policy may specify any valid version or leave the field unset.

`testIamPermissions(project, resource, body=None)`

    Returns permissions that a caller has on the specified resource.

    Args:
      project: string, Project ID for this request. (required)
      resource: string, Name or id of the resource for this request. (required)
      body: object, The request body.
        The object takes the form of:

    {
        "permissions": [ # The set of permissions to check for the 'resource'. Permissions with wildcards (such as '*' or 'storage.*') are not allowed.
          "A String",
        ],
      }

    Returns:
      An object of the form:

        {
        "permissions": [ # A subset of `TestPermissionsRequest.permissions` that the caller is allowed.
          "A String",
        ],
      }
