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

As mentioned above by Rajith Delantha, this solved the problem for me:

Add: DOCKER_OPTS=' -G jenkins' directly in /etc/default/docker.

Then restart docker service by sudo service docker restart.

Answer 2

I had the same issue with Jenkins.

Added jenkins to docker group

sudo usermod -aG docker jenkins

Then restrat jenkins.
