Kubernetes admission plugin config in kube-apiserver not applied correctly

[runatyr1]

For now i'm using ansible to configure the apiserver parameters.

After an ansible re-run found this:

- --enable-admission-plugins=NodeRestriction,MutatingAdmissionPolicy,MutatingAdmissionPolicy,ImagePolicyWebhook

Responsible file: scripts/bootstrap/k8s-enable-admission-plugins.sh

Issue must be caused to a recent addition of more than one plugin name for insertion. It was likely mishandled by the insertion script.

Found this was part of an archived feature not yet completed and was residual change.
For now leaving only one option and it is working now.
Later will need to change the script to handle more than one option changed.
