360云Ubuntu安装Dokcer

cat /etc/issue

Ubuntu 14.04.2 LTS \n \l

内核版本

uname -r

3.16.0-30-generic

相比阿里云，提供3.8.0-44-generic  的内核，ubuntu12，在360云就会好很多了，

备注

Docker is supported on these Ubuntuoperating systems:

• Ubuntu Vivid 15.04

• Ubuntu Trusty 14.04 (LTS)

• Ubuntu Precise 12.04 (LTS)

• Ubuntu Saucy 13.10

  Kernels older than 3.10 lack some of thefeatures required to run Docker containers. These older versions are known tohave bugs which cause data loss and frequently panic under certain conditions.

  如果Kenerl版本小于3.10，那么对docker的支持就会打折扣，甚至运行问题，在阿里云或者您选择较低版本的系统，需要对内核进行升级。话说这年头，程序员何苦为难程序员，直接选择最新版本安装。

   

  进行安装：

  sudo apt-getinstall docker.io

  After this operation, 46.6 MB of additionaldisk space will be used.

  Do you want to continue? [Y/n]

  aufs-toolscgroup-lite git git-manliberror-perl docker.io 这六个就是安装项目，看一下fs这个必须得

   

  安装完毕检查运行状态，因为这个是自启动的：

  service docker.io status

  docker.io start/running, process 2711

   

  docker默认路径Ubuntu

  /etc/apparmor.d/docker

  /usr/bin/docker

  docker -d

  这时候，建议把pid删除

  Cd /var/run

  Rm –f docker.pid

  重新启动docker –d

   

  新开一个Terminal，然后可以操作docker了

  dockerpull ubuntu

  可以看到Docker daemon

  下载执行完成后，在Docker daemon输出中也可以看到Job完成

  执行启动

  root@server-zyq9z8tu:~# dockerrun ubuntu /bin/echo "hello"

  使用前的自动拉取，除非你希望使用自己的img；镜像不存在的时候，它会自动的帮你去拉取。例如，
