Lab 4.2 - A Simple DAG Workflow: apply workflow with generate name

johchung

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

Hello

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

kubectl version --short

Client Version: v1.25.2
Kustomize Version: v4.5.7
Server Version: v1.27.4

Do you have any ideas?

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 []
