Question

我正在运行非常基本的 docker-compose 并遵循 docker-compose.yml 并出现以下错误。

docker-compose.yml

services:
  redis:
    image: redis
  db:
    image: postgres:9.4
    environment:
      - POSTGRES_USER=udcoker
      - POSTGRES_PASSWORD=udcoker
      - POSTGRES_DB=docker
  vote:
    image: voting-app
    ports:
      - 5000:80
    depends_on:
      - redis
  worker:
    image: worker-app
    depends_on:
      - redis
      - db
    environment:
      - POSTGRES_USER=udcoker
      - POSTGRES_PASSWORD=udcoker
      - POSTGRES_DB=docker
  result:
    image: result-app
    ports:
      - 5001:80
    depends_on:
      - db
    environment:
      - POSTGRES_USER=udcoker
      - POSTGRES_PASSWORD=udcoker
      - POSTGRES_DB=docker

产生错误，

我检查了各种 stackoverflow 现有问题，但没有一个解决实际问题。有人建议运行 postgres docker 并对其进行 bash 以更新密码，但这是一种解决方法。有人对此有任何具体的解决方案吗？

我终于想通了，很高兴分享mistake我做了什么。

如问题中所述，我通过在 db 服务的 environment 文件中提供 docker-compose.yml 变量来更改数据库配置，

environment:
      - POSTGRES_USER=udcoker
      - POSTGRES_PASSWORD=udcoker
      - POSTGRES_DB=docker

但同样需要在所有其他自定义服务（开源 github）中更新，这些服务尝试使用相同的用户/密码/数据库连接到此 depende-on postgres 数据库，但尚未完成。

然而 docker-compose 给出的错误并没有清楚地说明情况。

总而言之，我在连接属性中使用上述用户名/密码/数据库更新了应用程序，并且容器已启动。
