# 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:

      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.

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, orderBy=None, maxResults=None, pageToken=None, filter=None)`

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

    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. Acceptable values are 0 to 500, inclusive. (Default: 500)
      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, 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).

    Returns:
      An object of the form:

        { # A list of instance templates.
        "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_next(previous_request, previous_response)`

    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)

    Returns:
      A request object that you can call 'execute()' on to request the next
      page. Returns None if there are no more items in the collection.

`setIamPolicy(project, resource, body)`

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

    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. (required)

`testIamPermissions(project, resource, body)`

    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. (required)
        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",
        ],
      }
