(20210316已解决)docker-compose创建postgresql容器exited with code 1

• Overview

  通过docker-compose创建postgresql容器总是失败，log显示为containerName exited with code 1

  Exit Code 1: Indicates failure due to application error

• Solution

  docker-compose.yaml文件中添加environment变量：

  environment:
      POSTGRES_USER: example
      POSTGRES_PASSWORD: example1234
      POSTGRES_DB: example
  

  我猜想是，初始化时要指定用户名、密码、数据库
