That docker version looks ancient. Which hardware and OS are you running?
If you installed docker from the OS repository instead of from docker, this is the problems you might get.
Yeah Centos 7 basic repo version of Docker.
I wound up switching to Debian and using the Backporting thing to get minetest 5.0.1 instead of trying to work through the Docker issues.
Oh yeah, the centos repo version is notorious. Not sure what they did to the service but it causes numerous issues like the one you experienced.
We highly recommend installing from the official docker repo: https://docs.docker.com/install/
Also don’t install the snap version, that one also causes a lot of issues
