Recreate Your Cluster
There will be times when you want to wipe your whole environment and rebuild it fresh. I have provided an easy way to accomplish that.
There is a single script that will completely wipe the cluster and reset HA Proxy on the router for a new cluster.
Select the Lab subdomain that you want to work with:
Tear down the cluster and delete it’s resources:
Remember, we already destroyed the Bootstrap node.
labcli --destroy -c
In a matter of moments, the cluster will be completely gone.
Now, to recreate the cluster, first make any changes that you want to your cluster configuration YAML file.
Reinstall The Cluster:
Follow the directions here: Installing OpenShift
Redeploy any Worker Nodes:
Original Instructions Here: Add Worker Nodes

labcli --start -w

Approve the CSRs:

Note: There will be 3 CSRs for each Worker Node
