Docker play

https://www.docker.com/ 詳實的資料

其實你需要的是這個 https://docs.docker.com/

我使用的安裝平臺爲ubuntu12.04.5 內核3.13（必須,文檔上要求）

https://docs.docker.com/installation/ubuntulinux/

一步一步按照上面做

1. Log into your Ubuntu installation as a user with sudo privileges.

2. Verify that you have wget installed.

   $ which wget

   If wget isn't installed, install it after updating your manager:

   $ sudo apt-get update $ sudo apt-get install wget

3. Get the latest Docker package.

   $ wget -qO- https://get.docker.com/ | sh

   The system prompts you for your sudo password. Then, it downloads and installs Docker and its dependencies.

4. Verify docker is installed correctly.

   $ sudo docker run hello-world

   This command downloads a test image and runs it in a container.

裝好之後，我看到提示將自己普通用戶添加docker使用權限

sudo usermod -aG docker 你的用戶名

         然後你就可以開始享受docker的便捷與輕巧了

         一些簡單的命令就不說了，多練習一下能夠使用得差不多了，詳見https://docs.docker.com/userguide/

        裝完後，玩了一會docker過下癮，然後就跑去睡了，第二天起來開機，掛了

        出現kernel panic，提示大概意思是找不到root分區之類的信息，傻了，常用了alt+srq+reisub都沒用了，估計kernel都沒啓動

        怎麼都想不通啊，獲取翻文檔。

        好傢伙，忘記掛cgroup了。好吧，改！

        先用recovery mode進root 掛分區得到寫權限

       

1. Edit the /etc/default/grub file.

2. Set the GRUB_CMDLINE_LINUX value as follows:

   GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1"

3. Save and close the file.

4. Update GRUB.

   $ sudo update-grub

5. Reboot your system.

 做完後，謝天謝地，重啓成功，然後喜滋滋繼續用僞蘋果了
