## kops rolling-update cluster
|
|
|
|
Rolling update a cluster.
|
|
|
|
### Synopsis
|
|
|
|
|
|
This command updates a kubernetes cluster to match the cloud, and kops specifications.
|
|
|
|
To perform rolling update, you need to update the cloud resources first with "kops update cluster"
|
|
|
|
Note: terraform users will need run the following commands all from the same directory "kops update cluster --target=terraform" then "terraform plan" then "terraform apply" prior to running "kops rolling-update cluster"
|
|
|
|
Use export KOPS_FEATURE_FLAGS="+DrainAndValidateRollingUpdate"to use beta code that drains the nodes and validates the cluster. New flags for Drain and Validation operations will be shown when the environment variable is set.
|
|
