Selh-hosted runners can be ephemeral too. With such either mount the cache as a disk or bake docker layers/images into the runner image.

This requires a lot of work from a dev inf team, though. Not as straightforward for an average team.

I won't disagree. It should be easier imo. I guess this is why a cottage industry has sprung up addressing such e.g. https://news.ycombinator.com/item?id=39930908

Now I've seen everything...

It's actually pretty easy.

Setup GitHub app. Install the arc helm charts. Install a buildkitd statefulset.

Update parans on build to use buildkitd.

That's not to say there aren't better caching strategies, but a really basic ephemeral setup is right there.

I haven't used it yet but these two features make it the clear favourite for me in alternate github action runners
