Removing the Calico-System namespace

[alberk8]

I have remove the calico installation via the script below, But I the namespace remains. When I delete the namespace the status is terminating. I found that the there are two entries for calico-node and calico-cni-plugin in the service account, Roles, Role Binding. When trying to delete via kubectl it just hang.

What do i need to do to complete remove these and the namespace?

kubectl delete -f https://raw.githubusercontent.com/projectcalico/calico/v3.29.2/manifests/tigera-operator.yaml

Likely there are finalizers on those resources preventing them from being removed - you should remove the finalizers from any objects within the Namespace and that should allow them to be cleaned up.

I end up having to do this.

kubectl patch -n calico-system ServiceAccount/calico-node --type json --patch='[{"op":"remove","path":"/metadata/finalizers"}]'
kubectl patch -n calico-system ServiceAccount/calico-cni-plugin --type json --patch='[{"op":"remove","path":"/metadata/finalizers"}]'

kubectl patch -n calico-system ClusterRole/calico-node --type json --patch='[{"op":"remove","path":"/metadata/finalizers"}]'
kubectl patch -n calico-system ClusterRole/calico-cni-plugin --type json --patch='[{"op":"remove","path":"/metadata/finalizers"}]'

kubectl patch -n calico-system ClusterRoleBinding/calico-node --type json --patch='[{"op":"remove","path":"/metadata/finalizers"}]'
kubectl patch -n calico-system ClusterRoleBinding/calico-cni-plugin --type json --patch='[{"op":"remove","path":"/metadata/finalizers"}]'
