Multi-arch docker support

[NoUseFreak]

Is your feature request related to a problem? Please describe. I am running an arm64 based cluster and would like to run polaris. Any chance you could push multi-arch images?

Thanks for the feedback! We'll look into this for the upcoming 1.0 release

ARM now supported!

Actually I misread this - we're still only pushing AMD images, but we have an ARM binary

[rbren]

I've never built multi-arch images, but do you think the following would work?

• build a second ARM binary in the Dockerfile
• copy that ARM binary to our standard alpine distro
• add a flag to the helm chart like --set architecture=arm, which would use the ARM binary instead of the AMD binary

Hi,

I've been building locally using the following to support multiarch. I do build the go apps in the container, so they will build using the correct arch. You could lookup the arch to fetch the correct artifact if needed.

multiarch:
	docker buildx use $(project)-builder \
		|| (docker buildx create --name $(project)-builder && docker buildx use $(project)-builder)
	docker buildx inspect --bootstrap
	docker buildx build -t $(docker_image):$(version) \
	 	--platform linux/amd64,linux/arm64,linux/arm --push .
	docker buildx rm $(project)-builder
	@echo "Published version $(version)"

In this case, the image will (with a single tag) support multiple archs and it does not require helm changes and will work for mixed clusters.

@NoUseFreak / @rbren - thanks for looking into getting ARM images (or better multiarch images). I found this issue when i was trying to get Polaris on my raspberry pi 4 cluster. I just wanted to drop by and say I have built ARM image that work with RPI4 in case anyone else finds this issue and doesn't want to go through the trouble of building them.

Once the multi-arch builds are available this is obviously moot :)

+1 . I would love to use the official release for my raspberry pi cluster.

@lucasreed recently implemented this in another one of our projects. I'll get this on the list to update too.

+1 - would love this too

Happy to say this is now supported!
