出现无法删除的情况，是因为 kubelet 阻塞，有其他的资源在使用该 namespace，比如 CRD 等，尝试重启 kubelet，再删除该 namespace 也不好使。
在尝试以下命令强制删除也不好使：
#!/usr/bin/env bash
if [ -z "$1" ];then
echo "print input namespace"
exit -1
fi
kubectl get ns $1 -ojson | jq 'del(.spec.finalizers[0])' > 0000.json
curl -k -H "Content-Type: application/json" -X PUT --data-binary @0000.json http://127.0.0.1:8001/api/v1/namespaces/$1/finalize
echo kubectl delete ns $1
kubectl delete ns ```
解决：
1. 运行以下命令以查看处于“Terminating”状态的namespace：
```null
kubectl get namespaces```
2. 选择一个Terminating namespace，并查看namespace 中的finalizer。运行以下命令：
```null
kubectl get namespace -o yaml```
得到类似信息如下：
```null
creationTimestamp: "2019-11-20T15:18:06Z"deletionTimestamp: "2020-01-16T02:50:02Z"name: resourceVersion: "3249493"selfLink: /api/v1/namespaces/knative-eventinguid: f300ea38-c8c2-4653-b432-b66103e412db
- 导出 json 格式到 tmp.json:
kubectl get namespace -o json >tmp.json
- 编辑 tmp.josn，删除 finalizers 字段的值：

- 开启 proxy :
kubectl proxy```
6\. 打开新的terminal 窗口，运行以下命令：
```null
curl -k -H "Content-Type: application/json" -X PUT --data-binary @tmp.json http://127.0.0.1:8001/api/v1/namespaces//finalize
输出以下信息：
"selfLink": "/api/v1/namespaces/istio-system/finalize","uid": "2e274537-727f-4a8f-ae8c-397473ed619a","resourceVersion": "3249492","creationTimestamp": "2019-11-20T15:18:06Z","deletionTimestamp": "2020-01-16T02:50:02Z"```
7\. 检查该namespace 是否被删除：
```null
kubectl get namespaces
继续以上步骤删除其他 Terminating namespace。
