Use this procedure to install a new Docker image for ZooKeeper into the local repository of delegate hosts that are ZooKeeper ensemble nodes.

Identify the hosts in the ZooKeeper ensemble.
grep -E '^\b*SERVICED_ZK=' /etc/default/servicedThe result is a list of 3 or 5 hosts, separated by the comma character (,). The master host is always a node in the ZooKeeper ensemble.
