Podman Osx Arm64 Build Linux Amd Images

Table of Contents

Problem

You like me want to use podman on OSX (15.2 Sequoia) and build images for --platform=linux/amd64 :)

Welcome to my world!

Make sure you install rosetta:

what is Rosetta?:

Rosetta is a dynamic binary translator developed by Apple Inc. for macOS, an application compatibility layer between different instruction set architectures. It enables a transition to newer hardware, by automatically translating software. The name is a reference to the Rosetta Stone, the artifact which enabled translation of Egyptian hieroglyphs.[2]

softwareupdate --install-rosetta

more details you can find in podman-desktop docs Native Apple Rosetta translation layer .

podman init machine

podman machine init podman-machine-custom \ 
  --disk-size 60 \
  --rootful --cpus=4 \
  --memory=8192 \
  --image https://builds.coreos.fedoraproject.org/prod/streams/stable/builds/40.20241019.3.0/aarch64/fedora-coreos-40.20241019.3.0-applehv.aarch64.raw.gz

if you are using the default image from the release page (for me, it didn’t work for complicated image)!.

Reasonable question: how did I find the correct image?

First, I’ve tried fedora coreOS image directly instead of default image for podman machine init, and later if found its similar image to podman-machine.aarch64.applehv.raw.zst. Then I just pulled regular one, with the same version as podman 3.5.1.

Now we can check which podman machine we just created (don’t forget to run podman machine start):

$ podman machine info
host:
    arch: arm64
    currentmachine: podman-machine-custom
    defaultmachine: ""
    eventsdir: /var/folders/1x/rxqwb15s7l97hwq760gc75dc0000gq/T/storage-run-503/podman
    machineconfigdir: /Users/andrii.soldatenko/.config/containers/podman/machine/applehv
    machineimagedir: /Users/andrii.soldatenko/.local/share/containers/podman/machine/applehv
    machinestate: Running
    numberofmachines: 2
    os: darwin
    vmtype: applehv
version:
    apiversion: 5.3.1
    version: 5.3.1
    goversion: go1.23.4
    gitcommit: 4cbdfde5d862dcdbe450c0f1d76ad75360f67a3c

    built: 1732196420
    osarch: darwin/arm64
    os: darwin

Next if you see a problem during podman build while pulling images:

Error: short-name "go:latest" did not resolve to an alias and no unqualified-search registries are defined in "/etc/containers/registries.conf"

or

Error: short-name resolution enforced but cannot prompt without a TTY

You need to ssh to machine and update containers/registries.conf config:

podman machine ssh
$

create dir if it doesn’t exists and add config:

core@localhost:~$ mkdir -p $HOME/.config/containers/


root@localhost:~# vim $HOME/.config/containers/registries.conf

with content:

cat $HOME/.config/containers/registries.conf
short-name-mode="permissive"
unqualified-search-registries = ['docker.io']

For more details about configuring registries you can find in official documentations https://github.com/containers/image/blob/main/docs/containers-registries.conf.5.md.

Conclusion

Now you can build images using podman build --platform='linux/amd64' using you local Mac with arm64 architecture and deploy to kubernetes with amd64 ;)

done :tada:
