How do I actually get the output of kubectl kustomize into my cluster?

Question

I have a very simple kustomization.yaml:

configMapGenerator:
  - name: icecast-conifg
    files:
      - icecast.xml

When I run kubectl kustomize . it spits out a generated configMap properly, but how do I actually load it into my cluster? I'm missing some fundamental step.

With Kustomize you can use the -k (or --kustomize) flag instead of -f when using kubectl apply. Example:

kubectl apply -k <my-folder-or-file>

See Declarative Management of Kubernetes Objects Using Kustomize

do you happen to know if Argo will automatically apply kustomization.yaml? – user3056541 Mar 28 '21 at 07:18
I don't know. But if it checks out from Git it probably works as you do locally if every file is committed to Git. – Jonas Mar 28 '21 at 07:21

You could do for example

kubectl kustomize . | kubectl apply -f -
