最近在嘗試閱讀Docker源碼，一直想弄明白docker關于namespace等的代碼的在哪，以及怎么觸發。然而在閱讀時發現根本找不到代碼。。。想著還是先源碼安裝下docker，然后邊運行邊打印些調試信息看看再說

安裝之前

Docker源碼需在docker容器編譯環境中編譯，所以先安裝docker，安裝環境依舊是ubuntu14.04

echo "deb https://apt.dockerproject.org/repo ubuntu-trusty main" | sudo tee /etc/apt/sources.list.d/docker.listsudo apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609Dsudo apt-get updatesudo apt-get upgradesudo apt-get install docker-engine

起初是使用apt-get install docker.io安裝，但在編譯源碼的時候會遇到ARG錯誤。

安裝

docker的安裝命令很簡單，雖然錯誤很多= =

apt-get install make git golanggit clone https://git@github.com/docker/dockercd dockermake buildmake binary

遇到的問題與解決方案

Unknown instruction: ARG

原因：

Docker Hub's automated build is still running Docker 1.8 and doesn't support ARG yet. There is a github issue tracking their upgrade to 1.9.

解決方案：采用安裝最新的docker-engine方式

docker daemon啟動失敗

復制代碼 代碼如下:

解決方案：移除devicemap文件夾，如 mv /var/lib/docker/devicemapper/ .

make build出錯一
