9 Removing a Kubernetes Cluster
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.
Tip:
If you reinstall a Kubernetes module on hosts that were used in a previous Kubernetes
cluster, run the sudo kubeadm reset -f
command on each node before you
redeploy the module.
