​​Build automation for the post-container era. It's like Makefile and Dockerfile had a baby.

Earthly is a build automation tool for the post-container era. It allows you to execute all your builds in containers. This makes them self-contained, reproducible, portable and parallel. You can use Earthly to create Docker images and artifacts (eg binaries, packages, arbitrary files).

Earthly is meant to be used both on your development machine and in CI. It can run on top of popular CI systems (like Jenkins, Circle, GitHub Actions). It is typically the layer between language-specific tooling (like maven, gradle, npm, pip, go build) and the CI build spec.

Features:
- Reproduce CI failures
- Builds that run the same for everyone
- From zero to working build in minutes
- Build anything via containers - build images or standalone artifacts (binaries, packages, arbitrary files)
- Programming language agnostic - allows use of language-specific build tooling
- Reproducible builds - does not depend on user's local installation. Runs the same locally, as in CI
- Parallelism that just works - builds in parallel without special considerations the user has to make
- Mono-repo friendly - ability to split the build definitions across a vast directory hierarchy
- Multi-repo friendly - ability to import builds or artifacts from other repositories

  RUN go build -o build/go-example main.go
  SAVE ARTIFACT build/go-example AS LOCAL build/go-example

lint:
  RUN go get golang.org/x/lint/golint
  COPY main.go .
  RUN golint -set_exit_status ./...

docker:
  COPY +build/go-example .
  ENTRYPOINT ["/go-example/go-example"]
  SAVE IMAGE go-example:latest
