Meet Buildah, Podman's companion tool for builds

Podman does an excellent job in plain builds with Dockerfiles/Containerfiles and helps teams to preserve their previously implemented build pipelines without the need for new investments.

However, when it comes to more specialized build tasks, or when users need more control on the build workflow, with the option of including scripting logic, the Dockerfile/Containerfile approach shows its limitations. Communities struggled to find alternative building approaches that can overcome the rigid, workflow-based logic of Dockerfiles/Containerfiles.

The same community that develops Podman brought to life the Buildah (pronounced build-ah) project, a tool to manage OCI builds with support for multiple building strategies. Images created with Buildah are fully portable and compatible with Docker, and all engines are compliant with the OCI image and runtime specs.
