Remove nodes

You may want to remove master, worker, or etcd nodes from your existing cluster. This can be done by running the remove-node.ymlplaybook. First, all specified nodes will be drained, then stop some kubernetes services and delete some certificates, and finally execute the kubectl command to delete these nodes. Use--extra-vars flagto select the node(s) you want to delete

# If you don't remember them, find the node names in the inventory/mycluster/hosts.yml file
$ ansible-playbook -i inventory/mycluster/hosts.yaml -b remove-node.yml --extra-vars "node=<node1>,<node2>"

To delete the entire cluster, however, simply use the playbook reset.yaml.
