最初，它连接到mongodb群集并获取主机名，然后应用程序无法启动。
我的猜测是，由于应用程序已部署在Docker容器中，因此docker假定mongodb也已部署在另一个容器中，并尝试通过容器名称查找它。
关于如何解决此问题的任何建议都会很有帮助。
谢谢！
在副本集配置中，每个节点都由某个主机名引用。这些主机名必须是可解析的，并且可以从您的应用程序访问。
听起来您正在使用对主机有意义但在容器中不可解析的名称。在您的容器中，您还可以在连接字符串中使用其他主机名。然后，初始连接成功，但是驱动程序随后使用RS配置中定义的名称重新连接到每个RS成员，并且失败。
[您需要更改RS配置以使用可从主机和容器中解析的名称，或使现有名称可解析并可从容器访问。
“可访问”是指如果名称在不同环境中解析为不同的IP地址，则这些IP必须路由到有问题的节点。
