polaris-sidecar报域名解析失败

[leiwingqueen]

1. 问题描述

使用envoy和polaris-sidecar的方式注入到k8s pod中，发现polaris-sidecar一直报这个域名解析失败。

2024-12-31T15:45:15.171354Z     error   resolver/server.go:311  [agent] all resolvers failed for question from client, question: ;polaris.polaris-system.       IN       AAAA, client: 10.243.201.72:53776, client_network: udp

service配置

2. 期望结果

能正常解析到域名和使用服务网格的功能
