kubectl delete "$(kubectl api-resources --verbs=delete -o name | tr "\n" "," | sed -e 's/,$//')" --all

Answer 1

是的，使用client-go可以完成kubectl自己完成的任何事情。毕竟，kubectl使用client-go本身。

您可以查看kubectl源代码，了解它是如何执行以下操作的：

1. 获取支持delete谓词的api资源列表。有关如何执行此操作，请参见api-resources命令实现。
2. 对于找到的每个资源，获取具有要查找的标签和值的对象列表。查看Kubectl的get命令实现，了解如何执行此操作
3. 删除每个符合条件的对象。请参见Kubectl的删除命令实现。
