EXAMPLES
   Building a multi-arch manifest list from a Containerfile
       Assuming the Containerfile uses RUN instructions, the host needs a way
       to execute non-native binaries.  Configuring this is beyond the scope
       of this example.  Building a multi-arch manifest list shazam in
       parallel across 4-threads can be done like this:



                  $ platarch=linux/amd64,linux/ppc64le,linux/arm64,linux/s390x
                  $ buildah build --jobs=4 --platform=$platarch --manifest shazam .



       Note: The --jobs argument is optional, and the --manifest option should
       be used instead of the-t or --tag options.


   Assembling a multi-arch manifest from separately built images
       Assuming example.com/example/shazam:$arch images are built separately
       on other hosts and pushed to the example.com registry.  They may be
       combined into a manifest list, and pushed using a simple loop:



                  $ REPO=example.com/example/shazam
                  $ buildah manifest create $REPO:latest
                  $ for IMGTAG in amd64 s390x ppc64le arm64; do
                            buildah manifest add $REPO:latest docker://$REPO:IMGTAG;
                        done
                  $ buildah manifest push --all $REPO:latest



       Note: The add instruction argument order is <manifest> then <image>.
       Also, the --all push option is required to ensure all contents are
       pushed, not just the native platform/arch.


   Removing and tagging a manifest list before pushing
       Special care is needed when removing and pushing manifest lists, as
       opposed to the contents.  You almost always want to use the manifest rm
       and manifest push --all subcommands.  For example, a rename and push
       could be performed like this:



                  $ buildah tag localhost/shazam example.com/example/shazam
                  $ buildah manifest rm localhost/shazam
                  $ buildah manifest push --all example.com/example/shazam
