前言

nginx和php-fpm放在一个镜像里面，这样更好配置，但是有一个问题，这样不利于php-fpm和nginx两个服务动态扩容，因为二者的吞吐量可能不一样，同时扩容可能会造成资源浪费，但是分开，又会造成一个问题，那就是nginx和php-fpm如何通信的问题变得有些棘手。

以下是Dockerfile文件的内容，其余可以参考我的github地址。

如果觉得麻烦，也可以直接从远程仓库直接拉取下来：

$ docker pull crazyjums/nginx-php-fpm-alpine

安装完镜像之后，还可以通过docker-compose进行管理：

version: "3"
services:
  nginx-php-fpm:
    #    image: mmm
    build:
      context: .
      dockerfile: Dockerfile
    container_name: nginx-php-fpm-one
    ports:
      - 891:80
    tty: true
    volumes:
