边缘端访问云端时，边缘端解析域名失败

HusenHuang commented 8 months ago

What happened: 运行测试用例 examples/cloudzone.yaml 和 examples/edgezone.yaml 测试跨云边通信，由云访问边没有问题，边访问云出现 telnet hand住的情况 What you expected to happen: 边端能够访问云端

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?: 已经参考https://zhuanlan.zhihu.com/p/585749690 问题5自查过了，还是出现无法解析的问题在边缘端宿主机测试结果在边缘端 pod测试结果

Environment:

EdgeMesh version: 1.15
Kubernetes version (use kubectl version): 1.26.9
KubeEdge version(e.g. cloudcore --version and edgecore --version): 1.15.2
Containerd：1.6.28
Cloud nodes Environment:
- Hardware configuration (e.g. `lscpu`): - OS (e.g. `cat /etc/os-release`): Ubuntu 20.04.6 LTS - Kernel (e.g. `uname -a`): - Go version (e.g. `go version`): - Others:
Edge nodes Environment:

根据issueKubeEdge issue 3445里的指导，临时规避方式如下： a. 删除service b. kubectl delete objectsync --all c. 重启cloudcore、edgecore，重新部署edgemesh d. 重新创建service 这个也临时操作了，边缘端还是无法解析云端
