dag-workflow.yaml

apiVersion: argoproj.io/v1alpha1
kind: Workflow
metadata:
  generateName: dag-diamond-
  namespace: argo
...

Applying the yaml returns the following error

$ kubectl apply -f dag-workflow.yaml
error: from dag-diamond-: cannot use generate name with apply

I addressed this with the following change
generateName: dag-diamond- to name: dag-diamond

    kubectl apply -f dag-workflow.yaml should be changed to kubectl create -f dag-workflow.yaml

    @mstepien I just spent a ton of time trying to figure this out. What @enigmatik777 said. Please for update the course to use kubectl create instead of kubectl apply If you use apply instead of create it results in this not so useful error:
    cannot unmarshal object into Go struct field WorkflowSpec.spec.templates of type []
