What is happening when docker-maven plugin tries to build image?

Question

I am running Jenkins in a docker container and Jenkins tries to run my maven build. As part of the build, the docker maven plugin instructs it to build a docker image.

Answer 1

I had the same problem, but in my local machine.

I've got it after reading this comment in Github thread: https://github.com/docker/compose/issues/1214#issuecomment-256774629

It says:

Solution (from https://docs.docker.com/engine/installation/linux/debian/, does not only work with Debian):

Add the docker group if it doesn't already exist.

sudo groupadd docker

Add the connected user "${USER}" to the docker group. Change the user name to match your preferred user. You may have to logout and log back in again for this to take effect.

sudo gpasswd -a ${USER} docker

Restart the Docker daemon.

sudo service docker restart
