Postgresql 从docker compose启动的容器无法连接到其他容器

我有一个像这样的

我使用docker compose up启动它，它显示容器已启动

但由于某些原因，没有容器能够连接rabbitmq或postgres

rabbitmq

但是应用程序正在尝试连接

5772

，但是rabbitmq和

postgres的连接被拒绝，这也表明

psql: error: could not connect to server: could not connect to server: Connection refused

rihapp                   |     Is the server running on host "localhost" (127.0.0.1) and accepting
rihapp                   |     TCP/IP connections on port 5532? 

它还生成
.env
文件，其中包含应用程序的环境变量，如

DATABASE_URL=postgres://rdc:rdc@localhost:5532/pg_db
spring.datasource.url=jdbc:postgresql://localhost:5532/pg_db
spring.rabbitmq.host=localhost
spring.rabbitmq.port=5772

可能有什么问题？这感觉像是某种网络问题。
似乎您已将客户端配置为与
localhost:X
上的服务器联系，我是否正确

在这种情况下，您需要知道docker compose中的容器具有不同的网络cGroup，并且能够通过网桥接口相互连接。这意味着在容器中，您应该使用
rdcrabbitmq:5672
而不是
localhost:5772

是的，我将主机设置为localhost@lapots在这种情况下，容器中的客户端应该以服务的名义到达服务，例如
rdcrabbitmq:5672
或
rcdb:5432
所以我应该在docker compose中将它们设置为值o container\u name？我会使用它们的服务块的名称，并删除
container\u name:
选项。我应该使用什么端口？在
env
文件中，它使用
jdbc:postgresql://rdcdb:5532/pg_db
但仍然无法连接。虽然我可以使用
0.0.0.0:5532

进行外部连接，但它几乎总是表示“这个容器”。描述网络环境以及如何在容器之间连接。
