I just migrated multiple ARM64 GitHub action Docker builds from my self hosted runner (Raspberry Pi in my homeland) to Blacksmith.io and I’m really impressed with the performance so far. Only downside is no Docker layer and image cache like I had on my self hosted runner, but can’t complain on the free tier.
Thanks for sharing. I have a custom bash script which does the docker builds currently and swapping to useblacksmith/build-push-action would take a bit of refactoring which I don't want to spend the time on now. :-)
