What people use each for

The jobs each tool is most often brought in to do.

Crossplane

  • Creating unified control layers for multi-cloud infrastructurenot Buildah
  • Designing declarative APIs for infrastructure provisioningnot Buildah

Buildah

  • Building images in CI without a privileged Docker daemonnot Crossplane
  • Producing minimal images with tighter layer control than a Dockerfile givesnot Crossplane
  • Scripted image assembly where a Dockerfile is the wrong abstractionnot Crossplane

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Crossplane

  • Requires Kubernetes expertise and infrastructure
  • Steep learning curve for teams new to Kubernetes patterns
  • Provider ecosystem smaller than Terraform

Buildah

  • Linux only, with no native macOS or Windows support
  • Scriptable builds are powerful but less portable and less familiar than a Dockerfile
  • Narrow by design: it builds images and does not run them, so it needs Podman or another runtime alongside

Buildah: Is Buildah free?

Yes, open source with no licence fee.

Crossplane: What is Crossplane used for?

Crossplane is used to build control planes and platforms for infrastructure management, enabling platform teams to expose safe APIs to other teams.

Source
Buildah: Do I still need a Dockerfile?

No. Buildah reads Dockerfiles if you have them, but images can be built entirely from shell commands instead.

Buildah: How is Buildah different from Podman?

Buildah builds images; Podman runs them. Podman actually embeds Buildah for its build command, and the two are designed to be used together.
