# Google Container Engine API . projects . zones . clusters

## Instance Methods

Returns the nodePools Resource.

Creates a cluster, consisting of the specified number and type of Google Compute Engine instances. By default, the cluster is created in the project's [default network](/compute/docs/networks-and-firewalls#networks). One firewall is added for the cluster. After cluster creation, the cluster creates routes for each node to allow the containers on that node to communicate with all other instances in the cluster. Finally, an entry is added to the project's global metadata indicating which CIDR range is being used by the cluster.

Deletes the cluster, including the Kubernetes endpoint and all worker nodes. Firewalls and routes that were configured during cluster creation are also deleted. Other Google Compute Engine resources that might be in use by the cluster (e.g. load balancer resources) will not be deleted if they weren't present at the initial create time.

Gets the details of a specific cluster.

Lists all clusters owned by a project in either the specified zone or all zones.

Updates the settings of a specific cluster.

### Method Details

`create(projectId, zone, body, x__xgafv=None)`

    Creates a cluster, consisting of the specified number and type of Google Compute Engine instances. By default, the cluster is created in the project's [default network](/compute/docs/networks-and-firewalls#networks). One firewall is added for the cluster. After cluster creation, the cluster creates routes for each node to allow the containers on that node to communicate with all other instances in the cluster. Finally, an entry is added to the project's global metadata indicating which CIDR range is being used by the cluster.
