Failed to start Auth Data Store

Overview

I receive this error during a clean installation of UCP:

Failed to start Auth Data Store. Run "docker logs ucp-auth-store" for more details.

Resolution

There's a known issue originating from Docker Engine 1.11 where the hostname of a UCP node cannot be more than 48 characters long.

To resolve this issue, shorten your domain name to make it 48 characters or less.

Note: This issue is only valid with UCP 1.1.1 and Docker Engine 1.11
