## 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]
|
|
```
|
|
|
|
### Examples
|
|
|
|
```
|
|
# After the cluster has been edited or upgraded, update the cloud resources with:
|
|
kops update cluster k8s-cluster.example.com --yes --state=s3://my-state-store --yes
|
|
```
|
|
|
|
