如何 在Docker窗口中部署PHP开发环境
展开全部
环境部署一直是一个很大的问题,无论是开发环境还是生产环境,但是 Docker
将开发环境和生产环境以轻量级方式打包,提供了一致的环境。极大的提升了开发部署一致性。当然,实际情况并没有这么简单,因为生产环境和开发环境的配置是完全不同的,比如日志等的问题都需要单独配置,但是至少比以前更加简单方便了,这里以
PHP 开发作为例子讲解 Docker 如何布置开发环境。
一般来说,一个 PHP 项目会需要以下工具:
Web 服务器: Nginx/Tengine
Web 程序: PHP-FPM
数据库: MySQL/PostgreSQL
缓存服务: Redis/Memcache
这是最简单的架构方式,在 Docker 发展早期,Docker 被大量的滥用,比如,一个镜像内启动多服务,日志收集依旧是按照 Syslog
或者别的老方式,镜像容量非常庞大,基础镜像就能达到 80M,这和 Docker 当初提出的思想完全南辕北辙了,而 Alpine Linux
发行版作为一个轻量级 Linux 环境,就非常适合作为 Docker 基础镜像,Docker 官方也推荐使用 Alpine 而不是 Debian
作为基础镜像,未来大量的现有官方镜像也将会迁移到 Alpine 上。本文所有镜像都将以 Alpine 作为基础镜像。
Nginx/Tengine
这部分笔者已经在另一篇文章 Docker 容器的 Nginx 实践中讲解了 Tengine 的 Docker 实践,并且给出了
Dockerfile,由于比较偏好 Tengine,而且官方已经给出了 Nginx 的 alpine 镜像,所以这里就用
Tengine。笔者已经将镜像上传到官方 DockerHub,可以通过
<code>docker pull chasontang/tengine:2.1.2_f</code>
获取镜像,具体请看 Dockerfile。
PHP-FPM
Docker 官方已经提供了 PHP 的 7.0.7-fpm-alpine 镜像,Dockerfile 如下:
