我想释放一些后端服务配额。为此，我相信我首先必须删除实例组。但是，当我尝试删除使用该服务的实例组时，我收到以下消息:
The deletion of the instance group failed. Error: An unknown error has occurred in Compute Engine: "undefined". Error code: "undefined"
我也试过只删除后端服务，但它会弹出另一个。此外，我试图删除关联服务的负载均衡器，但也失败了。有什么想法吗？
最佳答案
如 documentation 中所述:
"To delete a backend service, you must first make sure that the backend service is not being referenced by any URL maps. If a URL map is currently referencing a backend service, you must delete the URL map to remove the reference."
