==== ENTRYPOINT vs CMD ====

The idea is: it should run with AND without the command name. Example with yamllint:

  * ''docker run --rm local/yamllint --version''
  * ''docker run --rm local/yamllint yamllint --version''

See: https://hub.docker.com/r/pipelinecomponents/base-entrypoint

==== docker utils ====

  * exemple : ''docker volume cp'' https://github.com/gdiepen/docker-convenience-scripts/blob/master/docker_clone_volume.sh
