Feature request description

Dockerfile recently added support for the COPY --exclude parameter, see https://www.docker.com/blog/new-dockerfile-capabilities-v1-7-0/. Would it be possible to add it to podman too?

You could use docker-buildx (BuildKit), before the feature is available in podman build (Buildah)

This needs to bed enhanced in Buildah

Seems reasonable to me. But would require work in imagebuilder, I blieve.

@nalind @flouthoc WDYT?

rhatdan commented

If you were interested in opening a PR that would help this along.

flouthoc commented

Yes imagebuilder changes are needed afaics, I can give this a stab if @slinkydeveloper is not already working on this.

nalind commented

The imagebuilder parts should have landed in openshift/imagebuilder#285.

rhatdan commented

Nice so this just needs plumbing with buildah and then podman.

@nalind @flouthoc any progress on this?

nalind commented

Yeah, the main stumbling block I hit is getting the conformance tests to pass, since they're turning up behavior which seems counterintuitive, to me at least, in a few cases.
