Can I install Docker over a server with pre-installed cPanel and CentOS 7? Since I am not aware of Docker, I am not completely sure whether it will mess with cPanel or not. I already have a server with CentOS 7 and cPanel configured. I want to know if I can install Docker over this configuration I mentioned without messing up?

Yes you can install docker over cPanel/WHM just like installing it on any other CentOS server/virtual machine.

Just follow these simple steps (as root):

1) yum install -y yum-utils device-mapper-persistent-data lvm2 (these should be already installed...)
2) yum-config-manager --add-repo    https://download.docker.com/linux/centos/docker-ce.repo
3) yum install docker-ce
4) enable docker at boot (systemctl enable docker)
5) start docker service (systemctl start docker)

The guide above is for CentOS 7.x. Don't expect to find any references or options related to Docker in the WHM interface. You will be able to control docker via command line from a SSH shell.

I have some docker containers already running on my cPanel/WHM server and I have no issues with them. I basically use them for caching, proxying and other similar stuff.

And as long as you follow these instructions, you won't mess-up any of your cPanel/WHM services/settings or current cPanel accounts/settings/sites/emails etc.

Not sure why you haven't tried this already!
