To run the pipeline within a Docker container, please build the image located in the ``docker/pipeline`` directory of the `repository <https://git.astron.nl/RD/preprocessing-cwl>`_:
Please modify and give the image an appropriate tag with the ``-t`` option. This requires one to install Docker on their system, either `Docker Engine <https://docs.docker.com/engine/>`_ (only available for Linux) or `Docker Desktop <https://docs.docker.com/desktop/>`_ (available for Windows, MacOS, and Linux). Instead of Docker, one could also use `Apptainer <https://apptainer.org/>`_ (previously called Singularity) on Linux.
Note: if the dependencies have not been installed manually and the pipeline is not ran inside a container, workflow components will attempt to run inside a Docker or Docker-compatible container environment. In this case, a Docker image is pulled from the repository's container registry.
