Today, I tried to remove a namespace in Kubernetes, and after few minutes, it was blocked with Terminating status:

Terminating status

I searched on internet, and found this topic on Github:

https://github.com/kubernetes/kubernetes/issues/60807#issuecomment-572615776

So, I executed the following command:

kubectl get namespace "namespacetodelete" -o json | tr -d "\n" | sed "s/\"finalizers\": \[[^]]\+\]/\"finalizers\": []/" | kubectl replace --raw /api/v1/namespaces/namespacetodelete/finalize -f -

wp-image-15145Namespace has been removed:

I can now deploy namespace with the same name, without any problems.
