Script to delete kubernetes namespaces that are stuck in a never-ending "Terminating" status

Pre-requisites

• Ensure that you can authenticate to the kubernetes cluster as a cluster admin. This will need you to have the appropriate kube config setup etc.
• Ensure that you are in the default namespace & the default service account is a cluster-admin. (you can temporarily add the role & remove it after you finish running this script)

Follow the steps below to delete any and all namespaces that refuse to get deleted even after removing all objects within them. [The test-* namespaces in the output above are an example of such namespaces that refuse to get cleaned up]

1. Run the kubernetes api proxy:

 anoopkumar »» kubectl proxy -p 8080 &

2. Clone and run the script in this repo:

 anoopkumar »» git clone [e-mail]:anokun7/delete-terminating-namespace.git
 anoopkumar »» delete-terminating-namespace/delete-ns.sh
Cleaning up test-1 namespace ...
Cleaning up test-2 namespace ...
Cleaning up test-3 namespace ...
Cleaning up test-4 namespace ...
Cleaning up test-5 namespace ...
... Done!

Confirm that the lingering namespaces have been cleaned up.
