No big brain time here. Totally agree with @fChk. OpenVZ is simply too limited to run Docker. I assume, given the kernel you mentioned and etc, you got a OpenVZ 7 (or rather Virtuozzo 7) VPS. They have an article for Docker that was last edited in 2016... well, to me that shows pretty much how supported it is... not at all anymore (it might have been supported in 2016 where Docker was not as advanced as it is now).

Here it is: https://wiki.openvz.org/Docker_inside_CT_vz7

Pretty poor, right?

Even their Docker for OpenVZ 6 is better in terms of description and explanation: https://wiki.openvz.org/Docker_inside_CT

And if you read carefully you will notice only really old versions of Docker are supported. Remember you are already running inside a container and that is a limited one, too.


Basically why even waste time with OpenVZ in 2020? A lot of business shifted to KVM because it is simply much better in everything overall. And when "low end" business shift to KVM... that even speaks enough for itself.


P.S.: False advertising... great provider. Would cancel the contract given how blatantly obvious they lie. It's just the old good "put honey on it and the flies will come".
