chainguard-dev/apko

apko is a project developed by Chainguard for building and publishing OCI container images using apk packages. It offers several key features, including full reproducibility, fast build times, small image sizes, and SBOM support. apko also supports the use of the s6 supervision suite for running multiple processes in a container. The installation process includes using Homebrew, installing from source, or using the apko container image. The quickstart process involves creating an apko file, building the image, and publishing it to a registry. apko was created to address the need for secure and reproducible container images, and its design is influenced by the ko and distroless projects. apko files are fully declarative, and to install bespoke tooling or applications, they must first be packaged into apk packages using the melange tool. For support and further reading, resources include the Chainguard Academy, the Kubernetes Slack channel, and the melange project. Related projects include the ko project for building Go projects and the kontain.me service for creating fresh container images on demand.
