Hi,
The lab has a problem whereby not all CRDs get created.
The workflow-controller is in CrashLoopBack
pod/workflow-controller-54f948fc6f-k7jxf 0/1 CrashLoopBackOff 5 (89s ago) 4m40s
To fix it I run:
cur l -sL https://github.com/argoproj/argo-workflows/releases/download/v4.0.5/install.yaml | kubectl apply --server-side -f -
The reload the deployment
k -n argo rollout restart deployment/workflow-controller
I hope this helps
