Forcibly deletes a Kubernetes namespace that is stuck deleting
|
|
|
|
Written to get rid of Knative namespaces knative-eventing, knative-serving and kourier-system which were all permanently stuck trying to delete
|
|
|
|
Doesn't do the actual deletion of the namespace, but deletes the finalizers to allow a namespace already stuck in deletion to be removed
|
|
|
|
WARNING: do not run this on a normal healthy namespace that you care about, as it will wipe out the finalizers
|
|
|
