## kops update cluster

Update a cluster.

### Synopsis

Create or update cloud or cluster resources to match current cluster state.  If the cluster or cloud resources already exist this command may modify those resources.

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

```
kops update cluster [flags]
```

### Examples

```
  # After cluster has been edited or upgraded, configure it with:
  kops update cluster k8s-cluster.example.com --yes --state=s3://my-state-store --yes --admin
```

### Options

```
      --admin duration[=18h0m0s]      Also export a cluster admin user credential with the specified lifetime and add it to the cluster context
      --allow-kops-downgrade          Allow an older version of kOps to update the cluster than last used
      --create-kube-config            Will control automatically creating the kube config file on your local filesystem (default true)
  -h, --help                          help for cluster
      --internal                      Use the cluster's internal DNS name. Implies --create-kube-config
      --lifecycle-overrides strings   comma separated list of phase overrides, example: SecurityGroups=Ignore,InternetGateway=ExistsAndWarnIfChanges
      --out string                    Path to write any local output
      --phase string                  Subset of tasks to run: assets, cluster, network, security
      --ssh-public-key string         SSH public key to use (deprecated: use kops create secret instead)
      --target string                 Target - direct, terraform, cloudformation (default "direct")
      --user string                   Existing user to add to the cluster context. Implies --create-kube-config
  -y, --yes                           Create cloud resources, without --yes update is in dry run mode
```
