docker 上的 postgres 运行 连接超时

Question

我在 docker 上有一个项目 运行 使用 laravel 和 postgres 。 在我的项目中，一切都很好，项目没有问题， 但是当我想使用 navicat 或 phpstorm 连接到容器上的数据库时，它给我这个错误：

could not connect to server : connection timed out . is the server running on host "172.18.0.4" and accepting tcp/ip connections on post 5432 ??

我的项目连接没有问题，详细信息：

DB_CONNECTION=pgsql
DB_HOST=project_database_1
DB_PORT=5432
DB_DATABASE=project
DB_USERNAME=postgres
DB_PASSWORD=123456

这是我的 docker 撰写文件：

知道我无法连接到数据库是怎么回事吗？？

  #PHP Service
  app:
    build:
      context: .
      dockerfile: php/Dockerfile
    depends_on:
      - pgsql
    image: digitalocean.com/php
    container_name: app
    restart: unless-stopped
    tty: true
    environment:
      SERVICE_NAME: app
      SERVICE_TAGS: dev
    working_dir: /var/www
    volumes:
      - ./:/var/www
      - ./php/local.ini:/usr/local/etc/php/conf.d/local.ini
    networks:
      - app-network


  #db
  pgsql:
    image: "postgres" # use latest official postgres version
    ports:
      - "5432:5432"
    env_file:
      - .env
    volumes:
      - database-data:/var/lib/postgresql/data/ # persist data even
    networks:
      - app-network

试试这个。使用 depends_on 你是说应用程序应该依赖于 pgsql。首先出现 pgsql 然后当你输入 docker-compose up

时你的应用出现
