Register Docker Host
This page allows you to tell Cloudmin that an existing system it manages is suitable for hosting Docker containers. To do this, the following fields must be filled in :

System hosting Docker containers
From the menu you must select a system that has the software installed and kernel version required to run Docker. Cloudmin does not yet have the ability to install these packages automatically.

Add Docker systems to DNS domain
If the master Cloudmin system runs a DNS server, this field will show a menu of local DNS domains to which the hostname of newly created Docker instances will be added. Because Docker container IP addresses can change on reboot, Cloudmin will automatically update any DNS record it creates to match the new IP.

Switch Docker Hub account
In order to upload Docker images to the Hub, you must first register for an account at https://hub.docker.com/ and then enter the login details for that account here. This is not needed if you plan to use only local images though.

Unlike other virtualization types, there are no fields for IP address allocation or a default backup destination, as these features are not yet supported by Cloudmin when using Docker.
