No space left on device when running job on photon-os

I'm using gitlab and gitlab-ci along with gitlab-runner.

Gitlab-runner is choking on my build jobs for a day now and I can't find a way to solve the problem.

The problem appears when the npm install command runs :

```

Well this seems to be a docker issue. It’s keeping a whole lot of dangling volumes.

check if you have some :

docker volume ls -qf dangling=true

Get rid of them with :

docker volume rm $(docker volume ls -qf dangling=true)
