Docker daemon not running on windows shared runner

GitLab CI/CD
1

I’m running a CI-Pipline under a windows shared runner on gitlab. The pipline tries to start a docker container from my gitlab docker registry. But it’s failing with the hint, that maybe the docker daemon is not running. So I modified my job definition to just run “docker info” to validate the environment.

The job is very basic for test:

windowsinstaller:
  stage: deploy
  tags: [ windows ]
  script:
    - docker info

The jobs starts running, gitlab is creating the new vm, here the shortened output:

ERROR: error during connect: Get http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.40/info: open //./pipe/docker_engine: The system cannot find the file specified. In the default daemon configuration on Windows, the docker client must be run elevated to connect. This error may also indicate that the docker daemon is not running.

Any idea, why the docker daemon is not running? In my opinion this should be provided by the shared runner of gitlab.

I’m looking forward to your answers, hoping the best :smiley:

I encountered the same error when executing docker login, which worked fine before updated to 15.8.2

I found a solution:

  before_script:
    - Start-Service -Name "docker"
    - docker login -u "$CI_REGISTRY_USER" -p "$CI_REGISTRY_PASSWORD" $CI_REGISTRY

Seems like docker service is not longer started in the shared runner.
