Quarkus 升級 vertx dns 解析器忽略 kubernetes dns

Question

我已經將quarkus的版本升級到2.8.0.CR1

我的 quarkus 應用程序混合使用了 camel、mutiny、resteasy、mongo、pubsub，而且似乎已經在所有應用程序上都被復制了。

與此同時，似乎對 vertx 進行了升級，引入了替代 dns 解析器。

然而問題是，當我現在嘗試通過我的 kubernetes 集群部署我的應用程序時，我遇到了 dns 解析問題。

如果我嘗試按原樣啟動它，則在嘗試連接到我的 spring-cloud-config 服務器（在初始化時）時會出現此故障。 該域無法解析，因為它使用了谷歌公共 dns。

如果我設置-Dvertx.disableDnsResolver=true但是它似乎甚至沒有連接到我的服務器（服務器端沒有收到請求，也沒有讀取配置）

如果我使用以前版本的 quarkus 啟動應用程序，我會得到：

有沒有辦法讓它正確使用我的本地 dns 配置？

Answer 1

我設置quarkus.naming.enableJndi=true並且沒有使用-Dvertx.disableDnsResolver並且我的應用程序再次開始使用預期的 dns
