No buildah command to lint Dockerfile before building ?

How do I lint a Dockerfile for syntax errors before running buildah bud -t <image_tag> . ?

I have several complex Dockerfiles with multi-line commands and bash tricks. I want to add a step in my pipeline to lint the Dockerfiles before building them.

Buildah and I believe docker build/podman build do not have the ability to lint Dockerfile/Containerfiles. I would figure their are other open source projects that can handle this.

All the popular open source projects for Dockerfile linting are somewhat out-of-date.

• hadolint's latest release is from 2022.
• dockerlint's latest release is from 2019.
• I heard that Red Hat used to provide an online service "Linter for Dockerfile" - https://access.redhat.com/labs/linterfordockerfile. It's no longer accessible.
