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 $ podman build --jobs=4 --platform=$platarch --manifest shazam .
Note: The --jobs
argument is optional, and the -t
or --tag
option should not be used.
Assuming example.com/example/shazam:$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 $ podman manifest create $REPO:latest $ for IMGTAG in amd64 s390x ppc64le arm64; do podman manifest add $REPO:latest docker://$REPO:IMGTAG; done $ podman 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.
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:
$ podman tag localhost/shazam example.com/example/shazam $ podman manifest rm localhost/shazam $ podman manifest push --all example.com/example/shazam
