Using Docker

Docker is supported in Plesk for the following operating systems: CentOS 7, RedHat 7, Debian 8, Debian 9, Ubuntu 14.04, and Ubuntu 16.04.

Indeed, Docker Incompatible with CloudLinux .

^^ yup, cgroup not mounted.

If you want to get a bit hack-ish you could try messing with the following but I would first try it in a dev environment;

tianon/cgroupfs-mount

Mark, Thank you for your input here, the problem with this is that I can't use it with CentOS yum package manager, Do you have a workaround?

Actually It will be a good idea to use a remote docker node connected to Plesk.

I tried to use the second node with docker installed on CentOS7 but I'm facing a communication issue with the node from Plesk, I followed this instruction step by step twice and downloaded all *.pem files to corresponding fields in Plesk and with some errors like : connection refused, connection timeout , no route. so I couldn't get to use this method. I also tried the none SSL port 2375 and disabled all kind of firewall and still getting refused.

But I think it will be more complicated setup and some update will break the building.

Any ideas much appreciated.
