Unable to use docker with Bamboo (Permission denied)

Question

I am trying to run a docker command in Bamboo, but I got a permission denied error:

Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock

I already made sure that docker.sock has the right permission and added the user bamboo and (just to be sure) bamboo-server to the docker group.

srw-rw----  1 root     docker      0 Feb 28  2019 docker.sock=

cat /etc/group | grep docker
docker:x:120:bamboo-server,bamboo

So all settings that help to solve the issue for others seem to be set, but I am stil receiving the error. Any ideas what more I can do to fix this?

Edit:

I have tried some more things regarding permission, but even after changing the permission to 777 Bamboo keeps failing and the error is the same:

Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock

This makes me think that it might not be a permission problem at all. But I can't figure out what the actual problem is. Any ideas where to look?

Answer 1

The solution was restarting the Bamboo. After the restart all worked fine.
