@eiriksm We have a very outdated version of nymediaas/chrome-headless on docker hub (>3y old, it can walk and talk at this point), and AFAIK this is manually pushed.

This wants to make the process automated.

I would like to move to not using this base image though. I have done some efforts from time to time to check if we can change this, but it's going to break for sure.

That being said, I guess this just pushes it to ghcr so that would be fine. So no breakage in sight if we just start to do that

I would like to move to not using this base image though.

Care to expand a bit on this?

[eiriksm]

My reason was: It seems to be unmaintained and out of date.

BUT

I was going to the docker hub page to get some verification of that claim, and it's actually not at all 🤔 I guess it was at some point but then resurrected?

[esolitos]

Yeah, I looked at the github and it looked relatively alive. 😄
But then again, they say the latest version is 100, while chrome is now at 120.. so.. Yeah, not the best. Perhaps I can replace the base image with the actual installation steps, they're very basic anyway.

Well, for now I mostly needed to test it with for this PR: https://github.com/nymedia/akademika_d8/pull/4433
