What you will be doing

In this small, self-guided workshop you will deploy and migrate a Redis database between hosts in a UCP cluster. You'll follow step-by-step instructions to:

1. Add a Docker License to a Docker UCP Cluster.
2. Add an extra UCP node the cluster so we can migrate a database between hosts.
3. Use Docker compose to deploy an app with Redis backed by Flocker volumes and add some data to the app.
4. Destroy the app. Argh!
5. Start the app back up on a different node to demonstrate data movement. Phew.
