的镜像，还有就是 alpine这个，截取一段中文介绍</p><blockquote><p>Alpine 操作系统是一个面向安全的轻型 Linux 发行版。它不同于通常 Linux 发行版，Alpine 采用了 musl libc 和 busybox 以减小系统的体积和运行时资源消耗，但功能上比 busybox 又完善的多，因此得到开源社区越来越多的青睐。在保持瘦身的同时，Alpine 还提供了自己的包管理工具 apk，可以通过 <a target="_blank" rel="noopener" href="https://pkgs.alpinelinux.org/packages">https://pkgs.alpinelinux.org/packages</a> 网站上查询包信息，也可以直接通过 apk 命令直接查询和安装各种软件。<br>Alpine 由非商业组织维护的，支持广泛场景的 Linux发行版，它特别为资深/重度Linux用户而优化，关注安全，性能和资源效能。Alpine 镜像可以适用于更多常用场景，并且是一个优秀的可以适用于生产的基础系统/环境。</p></blockquote><blockquote><p>Alpine Docker 镜像也继承了 Alpine Linux 发行版的这些优势。相比于其他 Docker 镜像，它的容量非常小，仅仅只有 5 MB 左右（对比 Ubuntu 系列镜像接近 200 MB），且拥有非常友好的包管理机制。官方镜像来自 docker-alpine 项目。</p></blockquote><blockquote><p>目前 Docker 官方已开始推荐使用 Alpine 替代之前的 Ubuntu 做为基础镜像环境。这样会带来多个好处。包括镜像下载速度加快，镜像安全性提高，主机之间的切换更方便，占用更少磁盘空间等。</p></blockquote><p>一方面在没有镜像的情况下，拉取 docker 镜像还是比较费力的，第二个就是也能节省硬盘空间，所以目前有大部分的 docker 镜像都将 alpine 作为基础镜像了<br>然后再来构建下<br><img data-src="https://i.loli.net/2020/03/21/56cuKf1ObvkBSG3.png"><br>这里还有个点，就是上面的那个镜像我们也是 EXPOSE 80端口，然后外部宿主机会随机映射一个端口，为了偷个懒，我们就直接指定外部端口了<br><code>docker run -d -p 80:80 dynamic_web</code>打开浏览器发现访问不了，咋回事呢<br>因为我们没看<code>trafex/alpine-nginx-php7:latest</code>这个镜像<a target="_blank" rel="noopener" href="https://hub.docker.com/r/trafex/alpine-nginx-php7">说明</a>,它内部的服务是 8080 端口的，所以我们映射的暴露端口应该是 8080，再用<code>docker run -d -p 80:8080 dynamic_web</code>这个启动，<br><img data-src="https://i.loli.net/2020/03/21/qDd2LVhz1Po4McX.png"></p></div><footer class="post-footer"><div
