问题总结

1. 删除Terminating的namespace

# 使用中替换rook-ceph
kubectl get ns rook-ceph -o json | jq '.spec.finalizers=[]' > ns-without-finalizers.json
cat ns-without-finalizers.json

kubectl proxy &
PID=$!
curl -X PUT http://localhost:8001/api/v1/namespaces/rook-ceph/finalize -H "Content-Type: application/json" --data-binary @ns-without-finalizers.json
kill $PID
