# Compute Engine API . instanceTemplates

## Instance Methods

Deletes the specified instance template. If you delete an instance template that is being referenced from another instance group, the instance group will not be able to create or recreate virtual machine instances. Deleting an instance template is permanent and cannot be undone.

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

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 and zone.

Retrieves the next page of results.

Returns permissions that a caller has on the specified resource.

### Method Details

`delete(project, instanceTemplate)`

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

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

    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:

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.

`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 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",
        ],
