You need root privileges and to be able to install docker.
I have an Ubuntu VPS hosted by Pair.com, which offers a Docker installation, so I don’t need root privileges to install Docker. However, Pair cautions that
Our Docker installations run in a rootless environment, which may limit certain applications.
(Docker description of “rootless”.)
Am I correct that I can’t use Discourse on this VPS because it can’t be installed and run in a “rootless” Docker?
