Configuration:

• Cluster: AKS v1.27.9
• Node pools:
  • UbuntuLinux, Standard_D8ads_v5
  • Windows2019, Standard_D8ads_v5
• Argo Workflows v3.4.9

This test pod fails with ErrImagePull:

apiVersion: v1
kind: Pod
metadata:
  name: argoexec-multiplatform
spec:
  containers:
  - name: argoexec
    image: quay.io/argoproj/argoexec:latest
    command: ["powershell.exe", "-Command"]
    args: ["echo 'Hello from Argoexec on Multi-Platform'"]
  nodeSelector:
    kubernetes.io/os: windows

Even though the image is multi-platform and the pod is being scheduled on a Windows node.

However changing tag from latest to latest-windows causes the image to pull successfully.

For most cases, I would simply use latest-windows and move on. However Argo Workflows prefers a single tag for argoexec.

I assume I’m missing something obvious as I can’t find posts from other users running into the same problem. Currently this issue prevents me from running the trivial hello-world examples in the docs.
