This tool is aimed to kill namespaces that stuck in Terminating mode after you try to delete it. Just calling this script without flags, it shows you the possible problemns that put your namespace in forever terminating mode.
It automates the tips by https://github.com/alvaroaleman in kubernetes/kubernetes#60807 (comment)
If it doesn't work for you, please, let me know. It is hard to force namespace in Terminating mode just to test it.
curl -s https://raw.githubusercontent.com/thyarles/knsk/master/knsk.sh | bash
wget -q https://raw.githubusercontent.com/thyarles/knsk/master/knsk.sh -O - | bash
In this mode, this script only shows the possible causes that put your namespaces in Terminating mode. If you want this script to try to fix the mess, clone this repository, set the execution bit to the knsk.sh script and look at advanced options by typing ./knsk.sh --help.
Just to see what are the possible commands to solve the problem by yourself, use the advanced mode like
./knsk.sh --dry-run --delete-all --force
knsk.sh [options]
--dry-run Show what will be executed instead of execute it (use with '--delete-*' options)
--skip-tls Set --insecure-skip-tls-verify on kubectl call
