This looks good, thanks ! |

This could probably be generalized to all geOrchestra docker images. |

I guess the list of files doesnt change, it's just the underlying FS used by docker that does copy-on-write and thus keeps a copy of each files before and after the chown which is actually used ? |

Yes, you're right Landry, that's exactly it. RUN chown in the Dockerfile results in duplication of the files in the image's layers. I think the --chown option has been added quite recently to ADD. |

Merged into 18.06 and ported to master. |
We have then to make sure that the CI on packages.g.o is compatible with this version |
