解決 Laradock 國內拉取鏡像時很是慢的問題

前言

Laradock 很是好用，這一點毋庸置疑，可是在國內拉取鏡像時很是的慢。

下面咱們以搭建 LNMP 爲例對這一狀況進行解決。

首先，經過我安裝過無數次的狀況發現以下特徵：

• nvm 很是慢，nodejs 就更慢了，由於經過 nvm 安裝的
• workspace 或者說只要使用了 ubuntu 系統的鏡像在執行 apt-get update | apt-get install xxx 時很是的慢，

這兩點緣由致使每當啓動容器時，在鏡像不存在的狀況下，時間都很長，還時不時的報錯 timeout，因此咱們接下來看看這兩個問題的解決方案。

NVM 慢的問題

設置 NVM_NODEJS_ORG_MIRROR
注：下面的步驟，因爲技術緣由我暫時還未提交到 Laradock 官方倉庫，你們請參考我 Fork 的項目：Laradock

簡單的修改方式

進入 workspace 打開 Dockerfile，在 RUN if [ ${INSTALL_NODE} = true ] 前增長一行命令：ENV NVM_NODEJS_ORG_MIRROR=https://npm.taobao.org/mirrors/node 這是設置 nvm 安裝 nodejs 時從哪一個鏡像下載源文件的參數，設置後，nodejs 安裝的飛快.

更簡單的方式

打開 .env 設置 WORKSPACE_INSTALL_NODE=false

WORKSPACE 慢的問題

提供一份腳本，將該腳本放到鏡像是依據 Ubuntu 系統的 Dockerfile 同目錄下，而後在第一次執行 apt-get update 前面增長兩行：

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

原理很簡單，修改 ubuntu 鏡像源，改成國內源，上面命令的意思是，將文件拷貝到指定目錄下，而後執行。

原本想經過 RUN if xx 的方式去修改鏡像源，可是報錯了。有興趣的能夠 clone 我 Fork 的 Laradock 項目 ，幫忙解決一下。
