kops rolling-update

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.

Examples

  # Roll the currently selected kops cluster
  kops rolling-update cluster --yes
  
  # Roll the k8s-cluster.example.com kops cluster
  # use the new drain an validate functionality
  export KOPS_FEATURE_FLAGS="+DrainAndValidateRollingUpdate"
  kops rolling-update cluster k8s-cluster.example.com --yes \
  --fail-on-validate-error="false" \
  --master-interval=8m \
  --node-interval=8m
  
  
  # Roll the k8s-cluster.example.com kops cluster
  # only roll the node instancegroup
  # use the new drain an validate functionality
  export KOPS_FEATURE_FLAGS="+DrainAndValidateRollingUpdate"
  kops rolling-update cluster k8s-cluster.example.com --yes \
  --fail-on-validate-error="false" \
  --node-interval 8m \
  --instance-group nodes
