• 执行删除 namespace 后处于卡顿已经3个多小时了
  
• 按照网上的 --force 和 --force --grace-period=0 都没用，还是删不掉
  
• 在外面看到了一篇文章，试了之后有效，原文地址
  懒得跳转也可以看我这个，一样的

删除步骤

• 首先将 namespace 的信息以 json 格式存储
  kubectl get namespace vela-system -o json > tmp.json

• 编辑 tmp.json，删除 spec.finalizers 下的内容，使之变成空数组，其他的不做改动，具体改动如下
  删除前：
  
  删除后：
  

• 在终端输入 kubectl proxy
  

• 新打开一个终端，输入
  curl -k -H "Content-Type: application/json" -X PUT --data-binary @tmp.json http://127.0.0.1:8001/api/v1/namespaces/${NAMESPACE}/finalize
  替换一下 namespace，我这边是
  curl -k -H "Content-Type: application/json" -X PUT --data-binary @tmp.json http://127.0.0.1:8001/api/v1/namespaces/vela-system/finalize

• 执行后输出一堆内容，此时再 kubectl get ns | grep vela 已经查不到了，删除成功
