I think a generic cache capability, like "cache node_modules", could cache docker layers (somewhere under
/var/lib/docker) just as well. It's nothing like https://circleci.com/docs/docker-layer-caching, where the cached layers are directly network-mounted onto your node, but I also don't think the service should specialize for docker.
But just saying, I would be really interested in caching capabilities. Many of my pipelines pull assets from S3 because for obvious reasons I don't want 1-2 gigabytes of images in my repo. We can save a lot of bandwidth and time with caching. That said, I would be interested to help implement this should there be a need.
Hopefully fixed by https://lists.sr.ht/~sircmpwn/sr.ht-dev/patches/31852.
Thanks! I will.
