A 'container image' is a snapshot of a container. You can host your container images with GitLab.
To start using container images hosted on GitLab you first need to login:
docker login gitlab-registry.cern.ch
Then you are free to create and upload a container image with build and push commands:
docker build -t gitlab-registry.cern.ch/cloud-infrastructure/cci-elements/image .
docker push gitlab-registry.cern.ch/cloud-infrastructure/cci-elements/image
No container image repositories in Container Registry for this project.
