windows10+docker desktop使用docker compose编排多容器构建dnmp环境
之前的文章都是单独搭建运行php容器、nginx容器、mysql容器、redis容器然后每个都要执行一条命令，比较麻烦。今天就来介绍一下docker compose容器编排工具，它就是把单独执行的容器命令组合起来放到一个文件docker-compose.yml中编排，使用它来自动部署多容器开发环境，这样就方便多了，以防命令多了混乱。
刚好我根据之前写的nginx,php,mysql,redis教程中的命令结合起来使用docker compose编排起来
实现一个由docker-compose.yml文件组合的自动化执行的demo
下面的单独安装nginx/php/mysql/redis教程我就不写了，
在本站docker分类下，截张图放下面，有兴趣的自行搜索
进入步骤：
创建docker-compose.yml编排文件，我已创建好
C:\Users\htz>cd dockers
C:\Users\htz\dockers>dir
驱动器 C 中的卷没有标签。
卷的序列号是 82E1-16B0
C:\Users\htz\dockers 的目录
2022/08/11 17:06 <DIR> .
2022/08/11 17:06 <DIR> ..
2022/08/11 17:10 1,292 docker-compose.yml
2022/08/10 17:52 <DIR> mysql
2022/08/04 16:07 <DIR> nginx
2022/08/09 11:09 <DIR> php
2022/08/11 18:08 279 php.dockerfile
2022/08/08 13:45 <DIR> redis
2 个文件 1,571 字节
6 个目录 61,237,252,096 可用字节把nginx,php,mysql,redis容器执行命令按规则写入docker-compose.yml文件中，
我已写好。 如下：

有看php.dockerfile这个文件吗，php74用了它，主要是用于安装一些依赖、扩展包使用build加载
在C:\Users\htz\dockers>目录中执行docker-compose命令构建项目
docker-compose up -d
以下是执行该命令后的过程，我直接复制下来
C:\Users\htz>cd dockers
C:\Users\htz\dockers>dir
驱动器 C 中的卷没有标签。

Creating redis-server ... done
Creating mysql-server ... done
Creating php74 ... done
Creating nginx-server ... done在docker desktop软件中看看
ok到此就完成nginx、php、mysql、redis容器的构建了
注意：
宿主机映射容器的文件夹、配置文件等操作就自行看第一张截图里面的单独安装容器的文章教程
我这里就不说了，上面是成品环境了(底部有我的git链接)，直接访问我的一个laravel网站项目。
最后一步，在navicat导入我laravel网站项目的数据库，就可以访问网站了。
看看效果
