During [CI/CD]() various [docker](https://www.docker.com/) images are used. All images that are used by the pipeline, are also stored in the [container registry](https://docs.gitlab.com/ee/user/packages/container_registry/) of this repository. In case of changes in `/docker` the pipeline is configured to update these images as well (stage: `Docker-update`).
