Question

我是Docker的新手。我正在尝试使用docker使用我已经在本地工作的现有设置来安装Magento2。我的网址是./，我的数据库位于/ var / lib / mysql中。当我做docker-compose up -d我的mysql容器最终停止工作并且容器没有链接到db。我不知道它为什么不工作或链接。

docker-compose.yml

version: '2'

services:
  web:
    build: .
    ports:
      - "80:80"
    volumes:
     - ./:/var/www/html
    links:
      - db
    env_file:
      - env
    depends_on:
      - db
  db:
    image: mysql:5.7.18
    volumes:
      - /var/lib/mysql:/var/lib/mysql
    env_file:
      - env
