错误：运行Docker-compose时连接被拒绝

时间：2020-06-12 09:31:57

标签： mongodb docker docker-compose dockerfile

我使用了SpringBoot rest api和MongoDB。我有三种不同的数据库，例如player-db，game-db和score-db。对于每个服务，我都有DockerFiles。 当我运行docker-compose up时出现错误： docker-shell中的错误：

我不知道如何解决此问题。 我是Docker的初学者。

问题出在网络上。请理解，每个容器都是一种单独的VM。在这里，您正在尝试连接到本地主机。这将不起作用，因为每个容器都将解析为其自己的回送。

您可以通过多种方式解决此问题：

  1. 由于所有容器都连接到相同的docker网络，因此您可以使用容器名称来解析各个容器名称。因此，您可以在这里使用db:27017连接到MongoDB。（推荐）
  2. 由于已对所有容器进行端口绑定，因此可以使用主机而不是localhost。因此，如果主机的专用IP为10.0.0.1，请使用10.0.0.1:27017连接到MongoDB。
  3. 使用主机网络，在这种情况下，端口绑定指令将无用，因为它将被忽略，并且每个服务都会自动绑定到它们自己的端口，并且您可以使用localhost连接它们中的每个（不推荐）< / strong>
