Running amd64 images in built-in K8S cluster on M1 Pro

[krzysztof-nawara-bp]

Hello,
I have M1 Pro CPU, but I would like to run amd64 docker images in my K8S cluster through Rosetta rather than arm64. I'm using the built-in, single-node cluster that OrbStack offers.

I found this issue:
#640
I'm not sure what do you mean by "removing kubernetes.io/arch=amd64 selector". I have tried to change beta.kubernetes.io/arch=arm64 and kubernetes.io/arch=arm64 labels on the orbstack node to amd64 but that doesn't work (the updates don't stick, they somehow get reset back to arm64).

Thank you

You can't change the labels on the node. Remove the selectors from your deployment instead.

@kdrag0n Thank you for quick response. I don't believe I have any arch-related selectors on my deployment. Are they added implicitly?

What image are you using? You may need to specify an image hash explicitly if it's multi-platform:

kubectl run -it test --rm --image=alpine@sha256:b31dd6ba7d28a1559be39a88c292a1a8948491b118dafd3e8139065afe55690a

@kdrag0n using the hash is not that friendly for systems that do amd64 only.
Do you think it would be possible to add an option for kubernetes to let one choose the default arch?

maybe alongside the kubelet config?
