<h3>Method Details</h3>
<div class="method">
    <code class="details" id="addNodes">addNodes(project, zone, nodeGroup, body=None, requestId=None)</code>
  <pre>Adds specified number of nodes to the node group.

Args:
  project: string, Project ID for this request. (required)
  zone: string, The name of the zone for this request. (required)
  nodeGroup: string, Name of the NodeGroup resource. (required)
  body: object, The request body.
    The object takes the form of:

{
    "additionalNodeCount": 42, # Count of additional nodes to be added to the node group.
  }

  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:

</div>

<div class="method">
    <code class="details" id="aggregatedList">aggregatedList(project, orderBy=None, maxResults=None, pageToken=None, returnPartialSuccess=None, filter=None, includeAllScopes=None)</code>
  <pre>Retrieves an aggregated list of node groups. Note: use nodeGroups.listNodes for more details about each group.

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.
  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.
  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 `=`, `!=`, `&gt;`, or `&lt;`.

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) ```
  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.

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.

<div class="method">
    <code class="details" id="deleteNodes">deleteNodes(project, zone, nodeGroup, body=None, requestId=None)</code>
  <pre>Deletes specified nodes from the node group.

Args:
  project: string, Project ID for this request. (required)
  zone: string, The name of the zone for this request. (required)
  nodeGroup: string, Name of the NodeGroup resource whose nodes will be deleted. (required)
  body: object, The request body.
    The object takes the form of:

{
    "nodes": [ # Names of the nodes to delete.
      "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).

  }

  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).

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.
  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.
  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`)
  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.
  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 `=`, `!=`, `&gt;`, or `&lt;`.

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:

    { # Contains a list of nodeGroups.
    "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.

      "startTime": "A String", # Start time of the window. This must be in UTC format that resolves to one of 00:00, 04:00, 08:00, 12:00, 16:00, or 20:00. For example, both 13:00-5 and 08:00 are valid.
    },

Specifically, the name must be 1-63 characters long and match the regular expression `[a-z]([-a-z0-9]*[a-z0-9])?` which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash.
  }

  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).

A `role` is a named list of permissions; each `role` can be an IAM predefined role or a user-created custom role.
      #
      # Optionally, a `binding` can 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.

<div class="method">
    <code class="details" id="setNodeTemplate">setNodeTemplate(project, zone, nodeGroup, body=None, requestId=None)</code>
  <pre>Updates the node template of the node group.

Args:
  project: string, Project ID for this request. (required)
  zone: string, The name of the zone for this request. (required)
  nodeGroup: string, Name of the NodeGroup resource to update. (required)
  body: object, The request body.
    The object takes the form of:

{
    "nodeTemplate": "A String", # Full or partial URL of the node template resource to be updated for this node group.
  }

  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:

      # You can use an operation resource to manage asynchronous API requests. For more information, read Handling API responses.
      #
      # Operations can be global, regional or zonal.
      # - For global operations, use the `globalOperations` resource.
