k8s删除Terminating状态ns

假设你要删掉两个ns资源，发现一直删不了处于terminating状态

首先试一下先把这个ns的所有pod都删掉

kubectl delete pod --all -n istio-system

还是不行的话，加个参数强制删除

kubectl delete pod --grace-period=0 –force

如果依然是卡死状态，就要使用下面的必杀技了

首先生成一个tmp.json文件

kubectl get namespace <terminating-namespace> -o json >tmp.json

 apiVersion: v1
 kind: Namespace
 metadata:
   creationTimestamp: 2018-11-19T18:48:30Z
   deletionTimestamp: 2018-11-19T18:59:36Z
   name: <terminating-namespace>
   resourceVersion: "1385077"
   selfLink: /api/v1/namespaces/<terminating-namespace>
   uid: b50c9ea4-ec2b-11e8-a0be-fa163eeb47a5
 spec:
   finalizers:
   - kubernetes
 status:
   phase: Terminating

然后修改这个json文件，把finalizers的kubernetes删掉

apiVersion: v1
 kind: Namespace
 metadata:
   creationTimestamp: 2018-11-19T18:48:30Z
   deletionTimestamp: 2018-11-19T18:59:36Z
   name: <terminating-namespace>
   resourceVersion: "1385077"
   selfLink: /api/v1/namespaces/<terminating-namespace>
   uid: b50c9ea4-ec2b-11e8-a0be-fa163eeb47a5
 spec:
   finalizers:
   - 
 status:
   phase: Terminating

然后把本机服务暴露在本地端口的8001端口上

kubectl proxy

 
Starting to serve on 127.0.0.1:8001

新开一个terminal，把修改后的tmp.json到要删除的ns资源目录下

curl -k -H "Content-Type: application/json" -X PUT --data-binary @tmp.json http://127.0.0.1:8001/api/v1/namespaces/<terminating-namespace>/finalize

这样就可以删掉了
