Kubernetes Namespaces stuck in Terminating status

by

I did something similar to rahul.tripathi except the curl did not work for me – I followed https://medium.com/@craignewtondev/how-to-fix-kubernetes-namespace-deleting-stuck-in-terminating-state-5ed75792647e which does the following:

NAMESPACE=
kubectl get namespace $NAMESPACE -o json > $NAMESPACE.json
sed -i -e 's/"kubernetes"//' $NAMESPACE.json
kubectl replace --raw "/api/v1/namespaces/$NAMESPACE/finalize" -f ./$NAMESPACE.json

Voila! Namespace is deleted

Update: One-liner version of this solution (requires jq)

NAMESPACE= ; kubectl get namespace $NAMESPACE -o json | jq 'del(.spec.finalizers[0])' | kubectl replace --raw "/api/v1/namespaces/$NAMESPACE/finalize" -f -

Update #2: Terraform version

resource "kubernetes_namespace" "this" {
  for_each = toset( var.namespaces )
  metadata {
    name = each.key
  }
  provisioner "local-exec" {
    when = destroy
    command    = "nohup ${path.module}/namespace-finalizer.sh ${each.key} 2>&1 &"
  }
}

namespace-finalizer.sh

sleep 30; kubectl get namespace $1 && kubectl get namespace $1 -o json | jq 'del(.spec.finalizers[0])' | kubectl replace --raw "/api/v1/namespaces/$1/finalize" -f -
