Docker上的Wordpress-组成不运行 [英] Wordpress on docker-compose no run

问题描述

这是我的docker-compose.yml

This is my docker-compose.yml

version: '2'
services:
  wordpress:
    image: wordpress
    ports:
      - "8080:80"
    environment:
      WORDPRESS_DB_PASSWORD: example
  db:
    image: mysql:5.7
    environment:
      MYSQL_ROOT_PASSWORD: example

服务正常运行，但是几秒钟后，wordpress容器停止了。

the services run normally, but, a few seconds later, the wordpress container stop.

这是我的docker log wordpress容器：

This is my docker logs wordpress container:

为什么会这样？

推荐答案

解决方案：

记住将mysql容器链接到wordpress容器：

Remember to link the mysql container to the wordpress container:

links:
   - db:mysql

像这样：

version: '2'
services:
  wordpress:
    image: wordpress
    ports:
      - "8080:80"
    links:
      - db:mysql
    environment:
      WORDPRESS_DB_PASSWORD: example
  db:
    image: mysql:5.7
    environment:
      MYSQL_ROOT_PASSWORD: example
