Docker 中的 Spring Boot 未连接到服务器上的 Mongo（无-Docker 化）
SpringBoot in Docker not connecting to Mongo on server (Non-Dockerized)
我在尝试连接到 mongodb 集群时出现以下错误 - ReplicaSet（非 dockerized）通过 dockerized [=28] 部署在三个不同的服务器上=]启动应用程序。

最初，它连接到 mongodb 集群并获取主机名，然后应用程序无法启动。
我的猜测是，由于应用部署在 docker 容器中，docker 假设 mongodb 也部署在另一个容器中并试图通过容器名称找到它。
任何关于如何解决这个问题的建议都会有很大帮助。
谢谢！
在副本集配置中，每个节点都由某个主机名引用。这些主机名需要可解析并可从您的应用程序访问。
听起来您使用的名称在主机上有意义，但在您的容器中无法解析。从您的容器中，您在连接字符串中使用了一些其他主机名。然后初始连接成功，但驱动程序随后使用 RS 配置中定义的名称重新连接到每个 RS 成员，但失败了。
您需要更改 RS 配置以使用可从主机和容器解析的名称，或者使现有名称可从容器解析和访问。
"Accessible" 表示如果名称在不同环境中解析为不同的 IP 地址，则这些 IP 必须路由到相关节点。

在副本集配置中，每个节点都由某个主机名引用。这些主机名需要可解析并可从您的应用程序访问。
听起来您使用的名称在主机上有意义，但在您的容器中无法解析。从您的容器中，您在连接字符串中使用了一些其他主机名。然后初始连接成功，但驱动程序随后使用 RS 配置中定义的名称重新连接到每个 RS 成员，但失败了。
您需要更改 RS 配置以使用可从主机和容器解析的名称，或者使现有名称可从容器解析和访问。
"Accessible" 表示如果名称在不同环境中解析为不同的 IP 地址，则这些 IP 必须路由到相关节点。
