postgresql - PostgreSQL + 元数据库连接被拒绝

Question

我正在尝试将 postgres 配置为与 springboot 和元数据库一起运行。每个服务都单独运行，但是当我尝试将 3 个服务放在一个 docker-compose 文件中时，我收到以下错误：

 Caused by: org.postgresql.util.PSQLException: Connection to 0.0.0.0:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.
metabase-container |    at org.postgresql.core.v3.ConnectionFactoryImpl.openConnectionImpl(ConnectionFactoryImpl.java:303)

但是，我已将 db 的端口 5432 映射到元数据库容器的端口 5432。

然而，它似乎不起作用。对这个问题有任何帮助吗？（请在下面找到我的 docker-compose 文件）

version: '2'

services:
  spring:
    image: 'realtime:latest'
    container_name: spring

      - db

尝试将MB_DB_HOST元数据库环境变量从0.0.0.0更改为db。
