Can I run Discourse in "rootless" Docker on VPS?

A post by Jay Pfaffman says

You need root privileges and to be able to install docker.

I have an Ubuntu VPS hosted by, 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?

There is a good chance it won’t work, but if you already have this VPS it may be worth a try.

Thanks. I’ll try that.
