Required. The ID of the Google Cloud Platform project that the cluster belongs to.

Required. The region in which to handle the request.

Optional. A filter constraining the clusters to list. Filters are case-sensitive and have the following syntax:field = value AND field = value ...where field is one of status.state, clusterName, or labels.[KEY], and [KEY] is a label key. value can be "*" to match all values. status.state can be one of the following: ACTIVE, INACTIVE, CREATING, RUNNING, ERROR, DELETING, UPDATING, STOPPING, or STOPPED. ACTIVE contains the CREATING, UPDATING, and RUNNING states. INACTIVE contains the DELETING, ERROR, STOPPING, and STOPPED states. clusterName is the name of the cluster provided at creation time. Only the logical AND operator is supported; space-separated items are treated as having an implicit AND operator.Example filter:status.state = ACTIVE AND clusterName = mycluster AND labels.env = staging AND labels.starred = *

Optional. The maximum number of clusters to return in each response. The service may return fewer than this value. If unspecified, the default value is 200. The maximum value is 1000.

Optional. A page token received from a previous ListClusters call. Provide this token to retrieve the subsequent page.
