K8S如何强制删除namespace

精选 原创

我们有时候会遇到 namespace 无法删除的情况是因为 finalizers 属性的原因

1.将cert-mamaner导出为json文件

kubectl get ns cert-manager -o json > cert.json



2.编辑cert.json文件，将spec内的内容全部删除，然后保存退出



#  修改前
"spec": {
  "finalizers": [
    "kubernetes"
  ]
},

# 修改后
"spec": {
},



3.开启 proxy



kubectl proxy --port=8081



4.调用 api 进行删除



curl -k -H "Content-Type: application/json" -X PUT --data-binary @cert.json http://127.0.0.1:8081/api/v1/namespaces/cert-system/finalize



5.执行完命令后运行



kubectl get ns
default           Active   244d
kube-system       Active   244d
kube-public       Active   244d
kube-node-lease   Active   244d
