1，namespace Terminating状态处理
在k8s集群中进行测试删除namespace是经常的事件，而为了方便操作，一般都是直接对整个名称空间进行删除操作。
$ kubectl get ns qasim NAME STATUS AGE qasim Terminating 24d
调用接口删除
开启一个代理终端 $ kubectl proxy Starting to serve on 127.0.0.1:8001
再开启一个操作终端
将test namespace的配置文件输出保存
$ kubectl get ns qasim -o json > qasim.json
删除spec下finalizers的内容及status部分的内容还有metadata字段后的","号，切记！
剩下内容大致如下：
{
"apiVersion": "v1",
"kind": "Namespace",
"metadata": {
"annotations": {
"cattle.io/status": "{\"Conditions\":[{\"Type\":\"ResourceQuotaInit\",\"Status\":\"True\",\"Message\":\"\",\"LastUpdateTime\":\"2020-10-09T07:12:17Z\"},{\"Type\":\"InitialRolesPopulated\",\"Status\":\"True\",\"Message\":\"\",\"LastUpdateTime\":\"2020-10-09T07:12:18Z\"}]}",
"lifecycle.cattle.io/create.namespace-auth": "true"
},

"selfLink": "/api/v1/namespaces/test",
"uid": "862d311e-d87a-48c2-bc48-332a4db9dbdb"
}
}
调接口删除
$ curl -k -H "Content-Type: application/json" -X PUT --data-binary @qasim.json http://127.0.0.1:8001/api/v1/namespaces/qasim/finalize

补充：删除rancher的相关namespace（谨慎操作！！！）
kubectl patch namespace cattle-system -p '{"metadata":{"finalizers":[]}}' --type='merge' -n cattle-system kubectl delete namespace cattle-system --grace-period=0 --force kubectl patch namespace cattle-global-data -p '{"metadata":{"finalizers":[]}}' --type='merge' -n cattle-system kubectl delete namespace cattle-global-data --grace-period=0 --force kubectl patch namespace local -p '{"metadata":{"finalizers":[]}}' --type='merge' -n cattle-system for resource in `kubectl api-resources --verbs=list --namespaced -o name | xargs -n 1 kubectl get -o name -n local`; do kubectl patch $resource -p '{"metadata": {"finalizers": []}}' --type='merge' -n local; done kubectl delete namespace local --grace-period=0 --force

2，pv Terminating状态处理
（1）可以执行如下命令强制删除（PV-NAME 替换成实际需要删除的 pv 名称）：
$ kubectl patch pv pv-name -p '{"metadata":{"finalizers":null}}'
（2）再次查看可以发现该 pv 已被删除：
