#StackBounty: #ubuntu #docker #gitlab #continuous-integration #docker-registry Gitlab Runner installation Docker in Docker

Bounty: 100

Alright, so I am trying to install, register and successfully use a Gitlab Runner as a container in docker with the executor docker, basically docker in docker. I had some problems with it but was able to solve them on my own.

I am running gitlab-ce in another container under the same host but this happens, I commited a java aplication that uses gradle.

When the project is “ran” by gitlab-runner it outputs this:

I am using on a dedicated server running Ubuntu 18.04, any ideas how to fix this because I don’t even know what’s at fault here.

So from my understanding it has something to do with docker login command so I tried it manually and got this:

root@MyServer / # docker login
Login with your Docker ID to push and pull images from Docker Hub. If you don't have a Docker ID, head over to https://hub.docker.com to create one.
Username: User
Password: 
Error saving credentials: error storing credentials - err: exit status 1, out: `Cannot autolaunch D-Bus without X11 $DISPLAY`

docker info outputs:

If I fix the “error storing credentials” and login will it also fix gitlab-runner’s problem?

Note: the image I was using for gitlab-runner is the official one at dockerhub gitlab/gitlab-runner

If you need any additional information, comment this and I will happily provide it…
