解决 Laradock 国内拉取镜像时非常慢的问题

前言

Laradock 非常好用，这一点毋庸置疑，但是在国内拉取镜像时非常的慢。

下面我们以搭建 LNMP 为例对这一情况进行解决。

首先，通过我安装过无数次的情况发现如下特征：

• nvm 非常慢，nodejs 就更慢了，因为通过 nvm 安装的
• workspace 或者说只要使用了 ubuntu 系统的镜像在执行 apt-get update | apt-get install xxx 时非常的慢，

这两点原因导致每当启动容器时，在镜像不存在的情况下，时间都很长，还时不时的报错 timeout，所以我们接下来看看这两个问题的解决方案。

NVM 慢的问题

设置 NVM_NODEJS_ORG_MIRROR
注：下面的步骤，由于技术原因我暂时还未提交到 Laradock 官方仓库，大家请参考我 Fork 的项目：Laradock

简单的修改方式

进入 workspace 打开 Dockerfile，在 RUN if [ ${INSTALL_NODE} = true ] 前增加一行命令：ENV NVM_NODEJS_ORG_MIRROR=https://npm.taobao.org/mirrors/node 这是设置 nvm 安装 nodejs 时从哪个镜像下载源文件的参数，设置后，nodejs 安装的飞快.

更简单的方式

打开 .env 设置 WORKSPACE_INSTALL_NODE=false

WORKSPACE 慢的问题

提供一份脚本，将该脚本放到镜像是依据 Ubuntu 系统的 Dockerfile 同目录下，然后在第一次执行 apt-get update 前面增加两行：

• COPY ./sources.sh /tmp/sources.sh
• RUN ./tmp/sources.sh aliyun

原理很简单，修改 ubuntu 镜像源，改为国内源，上面命令的意思是，将文件拷贝到指定目录下，然后执行。

本来想通过 RUN if xx 的方式去修改镜像源，但是报错了。有兴趣的可以 clone 我 Fork 的 Laradock 项目 ，帮忙解决一下。
