Buildah

Buildah is an open-source, Linux-based command-line tool for building OCI-compliant container images without requiring a full container runtime or daemon. It allows building images from scratch or using Dockerfiles, with fine-grained control over image layers. Buildah supports rootless builds in unprivileged environments and integrates seamlessly with Podman and Skopeo as part of the containers organization. It is commonly used in Kubernetes-based CI/CD pipelines to avoid Docker-in-Docker complexity. In 2026 the project moved into the podman-container-tools GitHub organization under the CNCF Podman Container Tools project, and its Go module path became go.podman.io/buildah. Buildah publishes no network API: the command line tool and the Go library are the entire interface.

Buildah is profiled on the APIs.io network. Tagged areas include Build Tools, CI/CD, Container Images, Containers, and Daemonless.

Buildah’s developer surface includes documentation, getting-started guide, engineering blog, release notes, support, CLI, changelog, and 22 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Open Source Surface applies to this provider. This product is open source and we read its repository directly, so Open Source Surface carries 10 points of the composite. It is scored from what the repository actually publishes — a security policy, a contribution guide, a release history, a code of conduct — read live from the provider rather than inferred from our own catalog pointers. This facet adds; nothing was taken away to make room for it. An open-source project is not excused from the commercial facets, because exemption would strip it of the points it does earn. If we have the wrong repository, or this product is not open source, say so on your provider repo and we will drop the facet rather than have you publish against it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 75 points between them, because both conditional facets apply and carry 25 points together. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/buildah: open an issue to ask a question, or submit a pull request to add artifacts.

  detail: Buildah is a locally-run Linux command line tool and Go library for building OCI images; it operates no service,
    so there is no API, no developer portal and no account to create — buildah.io serves only release announcements, an install
    guide and tutorials, and returns 404 for every /.well-known/ path, /llms.txt and /openapi.json.
