Patch an object in-place

[yujunz]

Is it possible to use kustomize to patch an object which is not one of the resources defined in kustomization.yaml?

For example, if I want to add an annotation to kube-system like.

kubectl patch ns kube-system -p '{"metadata": {"annotations": {"iam.amazonaws.com/allowed-roles": "[\"*\"]"}}}'

How could I do it in kustomize?

kustomize doesn't support that.

kube-system is special, but for other namespaces, you can manage them with annotations by kustomize.

Thanks for the explanation.

@Liujingfang1 😭 but fair.

Please how one would (or should ?) patch say, coredns deployment cpu/memory requests and limits, if the tool used to deploy the cluster (kubespray) could not allow it at the time, said cluster was deployed ?
