  • True, but I got two problems with that thought chain:

    1. I don’t want any outdated dependencies within my network. There might be a critical bug in them and if I back up the images, I keep those bugs with me. That seems pretty silly.
    2. If an application breaks because you updated dependencies, you either have to upgrade the application aswell or got some abandonware on your hands, in which case it’s probably time to find a new one.

  • I’m kinda confused by all of the people here doing that tbh.

    The entire point of dockerfiles is to have them produce the same image over and over again. Meaning, I can take the dockerfile, spin it up on any machine on gods green earth and have it run there in the exact same state as anywhere else, minus eventual configs or files that need to be mounted.

    Now, if I’m worried about an image disappearing from a remote registry, I just download the dockerfile and have it stored locally somewhere. But backuping the entire image seems seriously weird to me and kinda goes against of the spirit of docker.
