Chapter 10 Removing a Kubernetes Cluster

If you want to remove a Kubernetes cluster, use the olcnectl module uninstall command. For example, to uninstall the Kubernetes module named mycluster:

olcnectl module uninstall \
--environment-name myenvironment \
--name mycluster

On each node, the Kubernetes containers are stopped and deleted, the Kubernetes cluster is removed, and the kubelet service is stopped.

Uninstalling a module also removes the module configuration from the Platform API Server. If you uninstall a module and want to reinstall it, you need to create the module again using the olcnectl module create command.


If you reinstall a Kubernetes module on hosts that were previously used in a Kubernetes cluster, you may need to run the kubeadm reset -f command on each node before you redeploy the module.
