earthly/earthly

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