Hi. I might miss something obvious - I don't have deep knowledge about
containers, however, trying to migrate my docker-in-docker image
building CI job to buildah, I've encountered the following problem.
My image should be tagged with its real version and in addition with a
special marker tag (such as "devel" or "stable" or
"latest"). It seems
to be a common practice with images. While in docker, I could just call:
docker build -t "$CI_REGISTRY_IMAGE:$VERSION" -t
"$CI_REGISTRY_IMAGE:$MARKER_TAG"
docker push $CI_REGISTRY_IMAGE"
with buildah, it is more problematic as I cannot use multiple tags on
push (--all-tags switch has been also abandoned).
I tried:
buildah bud -t "$CI_REGISTRY_IMAGE:$VERSION" -t
"$CI_REGISTRY_IMAGE:$MARKET_TAG"
buildah push "$CI_REGISTRY_IMAGE:$VERSION"
"$CI_REGISTRY_IMAGE:$VERSION"
buildah push "$CI_REGISTRY_IMAGE:$MARKET_TAG"
"$CI_REGISTRY_IMAGE:$MARKET_TAG"
but while "buildah images --digests" shows the same digest for those two
tags, in the remote repository (GitLab CI container repository) these
tags have two different digests (also both differ from the local one). I
suspect there could be something changed in the manifest.
Q. How can I have one image (with one digests) tagged multiple times in
a container repository using buildah?
buildah version 1.18.0 (image-spec 1.0.1-dev, runtime-spec 1.0.2-dev) on
Fedora 33.

P.S. I've seen https://github.com/containers/buildah/issues/2034, but I
don't know if it is related.
