Do you backup your docker images? (lemmy.world)

Not containers and data, but the images. The point would be reproducability in case a remote registry does not contain a certain image anymore. Do you do that and how?

I mean...you have the container right there on your machine. If you're concerned, just run your own registry and push copies there when needed. This of course is all unnecessary, as you only need the Dockerfile to build a clean image from scratch, and it will obviously work if it's already been published.

    As long as the internet works and the image is still available.

    Which is kind of the whole point, homie.

    Again, it's nearly impossible to scrub the entire internet of the code to just run a single command and build a docker image of whatever you were running yourself. If you have the image locally, you can just push it anywhere you want.

    Keep Dockerfile, keep checkouts of what you're running, or push images locally. All very simple.
