# Google Container Engine API . projects . zones . clusters

## Instance Methods

Creates a cluster, consisting of the specified number and type of Google Compute Engine instances, plus a Kubernetes master endpoint. By default, the cluster is created in the project's [default network](/compute/docs/networking#networks_1). 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.

Gets a specific cluster.

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

Update settings of a specific cluster.
