我使用docker-compose up启动它，它表明容器已启动。

但是由于某些原因，没有容器能够连接Rabbitmq或postgres。
rabbitmq的日志表明它们已经启动

但是应用程序尝试连接5772，但是对于Rabbitmq和postgres，连接被拒绝了
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?
它还会生成.env个文件，其中包含APPS之类的环境变量
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
可能是什么问题？感觉就像是某种网络问题。
答案 0 :(得分：2)
似乎您已配置客户端以与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访问。这意味着在容器中，您应该使用rdcrabbitmq:5672而不是localhost:5772
