Cannot use docker with HC2

Post by gerrus »

Hello,
I'm having a problem with the docker. I can't get a single container to run.
i already tried everything i found on the internet. i deleted docker, reinstalled it, tried different versions.
always the same error message "docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?"
can someone help me please ?
what am I doing wrong, what else can I try?

Did you add the user account to docker group, log in and run groups command to see if the user is docker group?
Which kernel version are you running?
Can you run this script if your kernel is properly configured to run Docker?

I had the same issue earlier and resolved removing "-H fd:" in "/etc/systemd/system/multi-user.target.wants/docker.service"...Just not sure which OS was.
