Is Multi-architecture kubernetes possible in colima?

[artur-jablonski]

I start colima like this:

colima start --cpu 4 --memory 16 --arch aarch64 --vm-type=vz --vz-rosetta --network-address --kubernetes

Now I can run both linux/arm64 and linux/amd64 architecture docker containers:

~  docker run --platform linux/amd64 --rm busybox:latest  echo -n "life is good"                                                                 Mon Feb  9 15:24:17 2026

        "Architecture": "arm64",

I am trying to achieve the same with the kubernetes cluster provisioned inside colima by using the --kubernetes switch.

However it seems that the architecture of the k8s cluster is set to be linux/arm64

~  k get nodes                                                                                                                           212ms  Mon Feb  9 15:29:01 2026
NAME     STATUS   ROLES                  AGE     VERSION

 ~  k describe node colima | grep -i architecture                                                                                                 Mon Feb  9 15:29:04 2026
  Architecture:               arm64

And now pods that reference images that have `arm64 builds work, but the ones that only have amd64 fail during image pull:

spec.containers{ibmmq}: Failed to pull image "ibmcom/mq:latest": Error response from daemon: no matching manifest for linux/arm64/v8 in the manifest list entries: no match for platform in manifest: not found

What options do I have to run a mix of amd64 and arm64 pods in the cluster provisioned in colima?

is there anything like docker's --platform in k8s to force particular platform for a pod?

can the same k8s node handle multiple architectures?

if not is it possible to provision the kubernetes cluster with two nodes each handling different achitecture and then let the control plane to handle scheduling on appropriate node? How would I go about that.
