The official documentation can be found here.

What to do if the docker container hangs and does not respond to any command other than ctrl+c?

I have been running a nvidia docker image since 13 days and it used to restart without any problems using docker start -i <containerid> command. But, today while I was downloading pytorch inside the container, download got stuck at 5% and gave no response for a while.

I couldn’t exit the container either by ctrl+d or ctrl+c. So, I exited the terminal and in new terminal I ran this docker start -i <containerid> again. But ever since this particular container is not responding to any command. Be it start/restart/exec/commit …nothing! any command with this container ID or name is just non-responsive and had to exit out of it only after ctrl+c

I cannot restart the docker service since it will kill all running docker containers.
Cannot even stop the container using this docker container stop <containerid>

Please help.

    I had to restart docker process to revive my container. There was nothing else I could do to solve it. used sudo service docker restart and then revived my container using docker run. I will try to build the dockerfile out of it in order to avoid future mishaps.

    You can make use of docker RestartPolicy:
    docker update --restart=always <container>
    while mindful of caveats on the docker version you running.
