标题: namespace，pv 一直Terminating状态处理
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。
  1. $ kubectl get ns qasim
  2. NAME    STATUS        AGE
  3. qasim   Terminating   24d
复制代码
 调用接口删除
  1. 开启一个代理终端
  2. $ kubectl proxy
  3. Starting to serve on 127.0.0.1:8001
复制代码
  1. 再开启一个操作终端
复制代码
  1. 将test namespace的配置文件输出保存
  2. $ kubectl get ns qasim  -o json > qasim.json
复制代码
  1. 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！
  2. 剩下内容大致如下：<br>
复制代码
  1. {
  2.     "apiVersion": "v1",
  3.     "kind": "Namespace",
  4.     "metadata": {
  5.         "annotations": {
  6.             "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"}]}",
  7.             "lifecycle.cattle.io/create.namespace-auth": "true"
  8.         },
  9.         "creationTimestamp": "2020-10-09T07:12:16Z",
  10.         "deletionTimestamp": "2020-10-09T07:12:22Z",

  15.     }
  16. }

  75.   }
复制代码
　　 
补充：删除rancher的相关namespace（谨慎操作！！！）
  1. kubectl patch namespace cattle-system -p '{"metadata":{"finalizers":[]}}' --type='merge' -n cattle-system
  3. kubectl delete namespace cattle-system --grace-period=0 --force
  5. kubectl patch namespace cattle-global-data -p '{"metadata":{"finalizers":[]}}' --type='merge' -n cattle-system
  7. kubectl delete namespace cattle-global-data --grace-period=0 --force
  9. kubectl patch namespace local -p '{"metadata":{"finalizers":[]}}' --type='merge' -n cattle-system
  11. 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
  13. kubectl delete namespace local --grace-period=0 --force
复制代码
 
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）：
  1. $ kubectl patch pv pv-name -p  '{"metadata":{"finalizers":null}}'
复制代码
 （2）再次查看可以发现该 pv 已被删除：
