Registries

Container registry

Integrated container registry

GitLab provides predefined variables for accessing the registry

Images must be named according to the project path, e.g. …

…for project bar in group foo: gitlab.seatN.inmylab.de/foo/bar:latest

CI jobs receive environment variables:

• CI_REGISTRY
• CI_REGISTRY_USER
• CI_REGISTRY_PASSWORD
• CI_REGISTRY_IMAGE

Upload the previously built container image

1. Add before_script to login to registry using docker login

    job_name:
      before_script:
      - docker login -u "${CI_REGISTRY_USER}" -p "${CI_REGISTRY_PASSWORD}" "${CI_REGISTRY}"
   

2. Update build command to assign a proper tag

    job_name:
      script:
      - docker build --tag "${CI_REGISTRY_IMAGE}:${CI_COMMIT_REF_NAME}" .
   

Hands-On 2/2

1. Add push command to upload container image

    job_name:
      script:
      # ...
      - docker push "${CI_REGISTRY_IMAGE}:${CI_COMMIT_REF_NAME}"
   

2. Go to Packages & Registries > Container Registry
