What version of the Spin shim are you using? Could you gather containerd logs related to the pods that are stuck in container creating?

@devigned @Mossaka I hope this journalctl -u kubelet of the WASM-shimed AKS node helps: aks-kubelet.txt

additionally, when I try to scale
$ kubectl scale deployment distributor --replicas 3
pods get stuck in ContainerCreating

(side note: you can refer to this issue for accessing containerd logs in your cluster deislabs/containerd-wasm-shims#197)

I am currently using kwasm-node-installer main branch and that copies Spin : /deislabs/containerd-wasm-shims/releases/download/v0.10.0/containerd-wasm-shims-v2-spin-linux-$(uname -m).tar.gz
I think I found the kubelet / containerd logs on the AKS node. I will redeploy with single pods to get rid of noice in the logs to make analysis easier.

It would be great to see containerd logs
from enterprise-wasm.

All of the details about the shim starting and possibly failing will be contained at the containerd level. The Kubelet is a little too high level to provide the detail required to diagnose the issue.

Do you have any pointers for me where I could find containerd logs on an AKS node?

Can you try journalctl -u containerd?

thanks @Mossaka - that worked ... but + @devigned - since I switched to kwasm-node-installer this behavior seems to be gone
