The below script will delete :muscle: the provided namespace within the OpenShift cluster. If the cluster needs authorization, need to send the "Authorization: bearer token". That can be taken from running the oc whoami -t command.

This is more helpful when the namespace is under finializers deadlock situation. In this situation, the namespace will be in Terminating phase and will stuck there for ever. Even of oc delete project <namespace> will gives you below error :warning:.

Error from server (Conflict): Operation cannot be fulfilled on namespaces “": The system is ensuring all content is removed from this namespace. Upon completion, this namespace will automatically be purged by the system.

kubectl proxy
echo "Deleting the namespace <namespace>"
oc project <namespace>
oc delete --all all,secret,pvc > /dev/null
oc get ns <namespace> -o json > tempfile
sed -i '' '/"kubernetes"/d' ./tempfile
curl --silent -H "Content-Type: application/json" -X PUT --data-binary @tempfile http://127.0.0.1:8001/api/v1/namespaces/<namespace>/finalize

Now it’s gone :rocket: :racehorse: :satisfied:
