## Buildah and Podman relationship
Buildah and Podman are two complementary Open-source projects that are available on
most Linux platforms and both projects reside at [GitHub.com](https://github.com)
with [Buildah](https://buildah.io) [(GitHub)](https://github.com/containers/buildah) and
[Podman](https://podman.io) [(GitHub)](https://github.com/containers/libpod). Both Buildah and Podman are
command line tools that work on OCI images and containers. The two projects
differentiate in their specialization.

command line tools that work on Open Container Initiative (OCI) images and
containers. The two projects differentiate in their specialization.
Buildah specializes in building OCI images. Buildah's commands replicate all
of the commands that are found in a Dockerfile. Buildahs goal is also to
provide a lower level coreutils interface to build images, allowing people to build
containers without requiring a Dockerfile. The intent with Buildah is to allow other
scripting languages to build container images, without requiring a daemon.

with and without Dockerfiles while not requiring any root privileges.
Buildahs ultimate goal is to provide a lower-level coreutils interface to
build images. The flexibility of building images without Dockerfiles allows
for the integration of other scripting languages into the build process.
Buildah follows a simple fork-exec model and does not run as a daemon
but it is based on a comprehensive API in golang, which can be vendored
into other tools.
Podman specializes in all of the commands and functions that help you to maintain and modify
OCI images, such as pulling and tagging. It also allows you to create, run, and maintain those containers

In short, Buildah is an efficient way to create OCI images while Podman allows
you to manage and maintain those images and containers in a production environment using
familiar container cli commands. For more details, see the
