namespace，pv 一直Terminating狀態處理

1，namespace  Terminating狀態處理

$ kubectl get ns qasim
NAME    STATUS        AGE
qasim   Terminating   24d

呼叫介面洗掉

開啟一個代理終端
$ kubectl proxy
Starting to serve on 127.0.0.1:8001

再開啟一個操作終端

將test namespace的組態檔輸出保存
$ kubectl get ns qasim  -o json > qasim.json

洗掉spec下finalizers的內容及status部分的內容還有metadata欄位后的","號，切記！
剩下內容大致如下：

{
    "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"
        },
        "creationTimestamp": "2020-10-09T07:12:16Z",
        "deletionTimestamp": "2020-10-09T07:12:22Z",
        "name": "qasim",
        "resourceVersion": "471648079",
        "selfLink": "/api/v1/namespaces/test",
        "uid": "862d311e-d87a-48c2-bc48-332a4db9dbdb"
    }
}

調介面洗掉

$ curl -k -H "Content-Type: application/json" -X PUT --data-binary @qasim.json http://127.0.0.1:8001/api/v1/namespaces/qasim/finalize
{
  "kind": "Namespace",

      }
    ]
  },

  },

        "reason": "ContentHasNoFinalizers",
        "message": "All content-preserving finalizers finished"
      }
    ]
  }

補充：洗掉rancher的相關namespace（謹慎操作！！！）

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狀態處理

$ kubectl patch pv pv-name -p  '{"metadata":{"finalizers":null}}'
