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
You could do for example
kubectl kustomize . | kubectl apply -f -
