使用docker-compose配置两个wordpress网站时遇到的问题

考试前两天想给女票也搞个博客，单独测试好好的，一起部署怎么都上不去，关键是理论上完全没问题。。最后调了半天（真·半天）发现是天杀的docker-compose必须mount与nginx一样的路径来传递变量，我真的是心态爆炸。。
这还是我做二分测试做了大概十几次才发现的问题，好像国内和国外都没怎么见有人提到过，故写个博客发在网上，方便后来者取用。

这是一个截至文章发布时只有14个赞的答案，实在是难为这位老哥了。

贴个docker-compose双wordpress的配置吧

services:

  nginx:
    depends_on:
      - example1
      - example2
    image: nginx:alpine

    restart: unless-stopped
    ports:
