Show HN: Earthly – Build automation for the container era

This is awesome.<p>Vlad&#x27;s blog post at <a href="https:&#x2F;&#x2F;vladaionescu.com&#x2F;introducing-earthly-build-automation-for-the-container-era-55619c63c3e" rel="nofollow">https:&#x2F;&#x2F;vladaionescu.com&#x2F;introducing-earthly-build-automatio...</a> is a shorter introduction.<p>Reminds me of SourceHut&#x27;s CI infrastructure (that uses VMs, rather than containers, and IIRC doesn&#x27;t natively multi-stage in the same way - but has a similar use profile)

It&#x27;s basically Makefile + Dockerfile combined. That&#x27;s useful because you can get rid of ad-hoc shell scripts, and builds are deterministic.

The ability to create a docker image from multiple sub-images is pretty useful. I think you could also use Dockerfile multi stage builds for that, but it’s not as clean.
