Installing Ubiquiti UniFi Controller on CentOS Docker Container (Plesk)

This tutorial shows how I installed and setup Ubiquiti UniFi Controller on 1&1 CentOS 7 VPS web server using Docker Container.

• Login to Plesk Control Panel, open Docker, search for jacobalberty/unifi, and Run latest version.
  
• Uncheck Automatic port mapping and remap ports that are already used by other services on the server. In my case, I remapped port 8880 (to 8881) and port 8443 (to 8444).
