Currently I have a VPS server running CentOS with DirectAdmin panel on it. I managed everything from the panel and easily created new hosting packages for my client. As a programmer I demand much from my server, so since it is a managed VPS it consumes so much time to communicate with my provider.
So I want to order a unmanaged Ubuntu VPS and want to get started with docker. All my clients have to move to the new server as well.
What is best practice for dockerizing your VPS? I think I'm going to use Webmin and Virtualmin, do you install them outside of docker containers? Or can I build a docker image from the whole old VPS?
