Multi-arch ORAS artifacts #145
Description
If I have a multi-architecture kubernetes cluster (ie. amd64 and arm64 nodes) how does k8s-kata-manager handle this? I would assume we can reference a multi-architecture in the kata manager configuration for each runtime class. However, looking at the code it doesn't pull for a specific arch, so we can't pass in an ORAS reference resolves to a multi-arch manifest.
Ideally, k8s-kata-manager should be smart enough to pull the proper ORAS artifact for the node's architecture for installation of the runtimeclass, and we can pass in a multi-arch ORAS reference. If we don't have this ability then we'd need to maintain two DaemonSet instances and runtimeclass configurations for them; one for amd64 and another for arm64.
