Support linux/arm64 in docker build

[jpda]

Hello,

Can we publish multi-arch images to include linux/arm64? From what I can tell and my own experimentation, there is nothing arch-specific about the emulator, so this should only require the docker build process to include the required architectures via docker buildx --platform or in a build step.

For example, running:

docker manifest inspect mcr.microsoft.com/azure-app-configuration/app-configuration-emulator:1.0.2 | jq -r '.manifests[].platform | "\(.architecture)/\(.os)"'

produces

amd64/linux

I have a sample workflow that publishes to GHCR and sets platforms in the docker build action to include linux/amd64,linux/arm64.

It produces this container: https://github.com/jpda/aace-arm64/pkgs/container/aace-arm64

docker manifest inspect ghcr.io/jpda/aace-arm64:1.0.2 | jq -r '.manifests[].platform | "\(.architecture)/\(.os)"'

amd64/linux
arm64/linux

This would be very helpful for folks using apple silicon or WSL on Windows on ARM.

thanks

I had just added the App Configuration emulator via my Aspire setup and got this error:

[sys] Could not create the container: ContainerName = config-f2b35acd:
[sys] docker command 'InspectContainers' returned with non-zero exit code 1
[sys] object not found
[sys] container not found
[sys] Error response from daemon: No such container: config-f2b35acd
[sys] not all requested objects were returned
[sys] only 0 out of 1 containers were successfully inspected
[sys] docker command 'CreateContainer' returned with non-zero exit code 1
[sys] error
[sys] Unable to find image 'mcr.microsoft.com/azure-app-configuration/app-configuration-emulator:1.0.2' locally
[sys] error
[sys] 1.0.2: Pulling from azure-app-configuration/app-configuration-emulator
[sys] error
[sys] no matching manifest for linux/arm64/v8 in the manifest list entries

Looks like there's not image that can run on the Apple Silicon, yet.

What I've done, to unblock myself and the team, is build the emulator myself and create the image on my local machine with the expected tag. Works like a charm, but rather annoying to rely on.

Is there an ETA on this? We are having to use annoying workarounds with the engineering team, and would really help for this to be supported.

Hey, John Patrick Dandison (@jpda) martinfletchersustainware Jan de Vries (@Jandev)
I am looking into this.

Is there an ETA on this?

I think we can support it by August. The AppConfig team is currently undergoing a reorg and is a bit understaffed at the moment. We'll make sure to support ARM as quickly as possible.

Doh! We hit this snag too. We've have devs on Win/Linux/Mac and just set up Aspire to run this emulator within our linux dev container. Unfortunately the mac folks can't run it.

Looking forward to the support! (Time to nag Fowler? lol)

Zhiyuan Liang (@zhiyuanliang-ms) - Amazing news!

Can the community help here if you guys are understaffed currently? Where would people be able to get information on helping out if possible?

[Jandev]

I just discovered I'm hitting similar issues with the Cosmos DB Emulator, which is also troublesome to work with on Mac. But I guess that's another repository, will try to see if I can get that fixed too somehow.

Thanks for the ETA though and if we can help out with something, let us know as martinfletchersustainware suggests too.

Really appreciate the offer to help!

The main workload here is actually around our internal build/release pipeline rather than the emulator itself. ARM support is definitely on our radar, and we'll try to get it out as soon as we can.

FWIW. If you first manually pull the linux/amd64 arch image down Aspire will find it and use it just fine on Mac.

i.e. docker pull --platform linux/amd64 mcr.microsoft.com/azure-app-configuration/app-configuration-emulator:1.0.2

Alternatively, you can do this too to force it to pull the image you want.

.RunAsEmulator(x => x.WithContainerRuntimeArgs("--platform", "linux/amd64") )

amd64 arch image has been released!

[martinfletchersustainware]

Amazing - Thanks for the quick turnaround on this!

Will get the team to give it a go tomorrow!
