Docker ps shows running container that I cannot stop or kill. How to stop/kill that container?

Question

"Docker p"s shows 1 running container. The command "docker ps --filter status=running" shows the same process.

When trying to stop the container, I get the identification but nothing happens. The container is still running.

When I performing a 'docker kill id' I get:

Error response from daemon: Cannot kill container: xyz: Container 2f-etc is not running

I cannot perform a 'docker container rm name' because of this message:

Error response from daemon: driver "overlay2" failed to remove root filesystem for 2f-etc: remove /var/lib/docker/overlay2/0877e30fd3a98f46b981827b52aec02a7004649e2a9c01c72e38cc8de5b309b0/diff/tmp/hsperfdata_root/5: read-only file system

How to stop / kill that container?

What do I know more:

• It may be that I stopped my computer without stopping the container. I will take care ;-)
• I noticed also that creating a new image with 'docker build -t newname .' is failing because: Error response from daemon: mkdir /var/lib/docker/tmp/docker-builder471922504: read-only file system

Answer 1

The issue in my case was that I had docker installed from snap on Ubuntu server. After a bit of search I found that this might be an issue:

I followed the steps here, and then reinstalled with apt, and now it works.

For reference, there's a bigger discussion about docker installed through snap having some issues at: Docker Containers can not be stopped or removed - permission denied Error

Answer 2

Sometimes docker restart doesn't work, so you may have to individually run docker stop & docker start. Thereafter use the docker container rm <container> command to remove.

Answer 3

Restart docker is simple but global solution. In my case I needed to keep other containers working without stop and the solution of @juanlumn helped me, which is docker container rm -f name (it removes container).

Answer 4

As @Aderemi Dayo suggested - a restart of the Docker machine suffices.
