问题处理

• ns terminal导致pod删除失败

##nsz资源转json
kubectl get ns  ingress-nginx   -o json >  ingress-nginx.json

## 清空spec字段
vim  ingress-nginx.json
--------------前
"spec": {
        "finalizers": [
            "kubernetes"
        ]
    },
---------------后
    "spec": {
    },

##启临时api
kubectl proxy --port=8081
##另起一个sh窗口 传递json配置覆盖删除
curl -k -H "Content-Type:application/json" -X PUT --data-binary @ingress-nginx.json http://127.0.0.1:8081/api/v1/namespaces/ingress-nginx/finalize
