Kops update cluster

kops update cluster ¶

Update a cluster.

Synopsis ¶

Create or update cloud or cluster resources to match the current cluster and instance group definitions. If the cluster or cloud resources already exist this command may modify those resources.

If, such as during a Kubernetes upgrade, nodes need updating, a rolling-update may be subsequently required.

kops update cluster [CLUSTER] [flags]

  kops update cluster k8s-cluster.example.com --yes --state=s3://my-state-store --yes
