    depends_on:
        - postgresql
        - redis
        - broker
    ports:
        - '3000:3000'

-DOCKER-COMPOSE

Redis - connection to 0.0.0.0:6379 failed - connect ECONNREFUSED 0.0.0.0:6379"

Postgres - Error: connect ECONNREFUSED 0.0.0.0:5432

我能够在容器外部访问postgres，redis，但是nodejs应用无法连接到两者并给出错误

所以任何想法，我做错了什么或错过了什么。

Answer 1

您的Node.js应用应尝试连接到redis:6379。在您的应用程序配置中更改此设置。目前，它似乎正在尝试连接到本地主机（当您在主机上本地运行服务器时，该主机可能会工作）。

无法从docker容器中的nodejs服务器连接到postgres，redis：获取连接ECONNREFUSED
