Integrating Buildah in custom builders
As we saw in the previous section of this chapter, Buildah is a key component of Podman's container ecosystem. Buildah is a dynamic and flexible tool that can be adapted to different scenarios to build brand-new containers. It has several options and configurations available, but our exploration is not yet finished.
Podman and all the projects developed around it have been built with extensibility in mind, making every programmable interface available to be reused from the outside world.
Podman, for example, inherits Buildah capabilities for building brand-new containers through the podman build command; with the same principle, we can embed Buildah interfaces and its engine in our custom builder.
Let's see how to build a custom builder in the Go language; we will see that the process is pretty straightforward, because Podman, Buildah, and many other projects in this ecosystem are actually written in the Go language.
