Containerfile with RUN --network none ... Does not work.

[rhatdan]

Dockerfile is documented to support

RUN --network ...

But with Buildah this blows up:

STEP 1/2: FROM alpine STEP 2/2: RUN --network=none ping -c 1 4.2.2.2 error building at STEP "RUN --network=none ping -c 1 4.2.2.2": RUN only supports the --mount flag

@flouthoc PTAL

Sure, SGTM I think a small change in imagebuilder should make it work.

A friendly reminder that this issue had no activity for 30 days.

I'm taking over https://github.com/openshift/imagebuilder/pull/237 and will implement this there.
