我正在构建一个使用postgresql在NodeJS上运行的应用程序.我正在使用SequelizeJS作为ORM.为了避免使用真正的postgres守护进程并在我自己的设备上安装nodejs,我正在使用带有docker-compose的容器.

当我运行docker-compose up 它时启动pg数据库

database system is ready to accept connections

和nodejs服务器.但是服务器无法连接到数据库.

Error: connect ECONNREFUSED 127.0.01:5432

如果我尝试在不使用容器的情况下运行服务器(在我的机器上使用真正的nodejs和postgresd)它可以工作.

但我希望它与容​​器一起正常工作.我不明白我做错了什么.

这是docker-compose.yml文件

web:
  image: node
  command: npm start
  ports:
    - "8000:4242"
  links:
    - db
  working_dir: /src
  environment:
    SEQ_DB: mydatabase
    SEQ_USER: username
    SEQ_PW: pgpassword
    PORT: 4242
    DATABASE_URL: postgres://username:pgpassword@127.0.0.1:5432/mydatabase
  volumes:
    - ./:/src
db:
  image: postgres
  ports:
  - "5432:5432"
  environment:
    POSTGRES_USER: username
    POSTGRES_PASSWORD: pgpassword

有人可以帮帮我吗？

我有一台安装了PostgreSQL的服务器.我的所有服务都在容器中工作(docker-compose).我想从容器中使用我的Host PostgreSQL.买我有错误:
