Kubernetes built with Earthly

Earthly is a very pragmatic iteration from the existing ecosystem of container build tools available today. It combines the best of Dockerfiles and Makefiles to provide a target-based containerized build system to provide consistently repeatable and reproducible builds. Earthly takes it a step further by understanding target dependencies and running targets in parallel when possible by leveraging the isolation characteristics of containers.

This project uses Earthly to build the Kubernetes project. See the Earthfile to see how it can be adopted for any existing project that may already be using Docker or Make, even for large projects like Kubernetes.

Example targets

Here are some examples of common targets to run.

Run all unit and integration tests:

$ earthly +test-all

Run all verify checks:

$ earthly -P +verify

Run all update scripts:

$ earthly +update

Build components:

$ earthly +build

Build a specific component:

$ earthly --build-arg WHAT=kubelet +build

Produce Kubernetes release artifacts:

$ earthly -P +release

Caveats

• Earthfile feature flag --no-implicit-ignore is required and was added in https://github.com/earthly/earthly/pull/1297.
• Some targets that run in parallel use a lot of resources and may crash in systems without enough memory.
