1.檢查系統內核版本，至少高於3.10.
root@ubuntu02:~# uname -r
4.4.0-31-generic
root@ubuntu02:~# cat /proc/version
Linux version 4.4.0-31-generic (buildd@lgw01-43) (gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04.3) ) #50~14.04.1-Ubuntu SMP Wed Jul 13 01:07:32 UTC 2016
2.檢查ubuntu具體版本.
root@ubuntu02:~# cat /etc/issue
Ubuntu 14.04.5 LTS \n \l
3.安裝額外依賴包，是爲了docker可以使用aufs存儲功能，實踐上系統已經默認安裝了。
root@ubuntu02:~# apt-get install -y linux-image-extra-$(uname -r)
Reading package lists... Done
Building dependency tree
Reading state information... Done
linux-image-extra-4.4.0-31-generic is already the newest version.
linux-image-extra-4.4.0-31-generic set to manually installed.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
root@ubuntu02:~#
4.安裝https協議源，實踐上系統已經默認安裝了.
root@ubuntu02:~# apt-get install -y apt-transport-https
Reading package lists... Done
Building dependency tree
Reading state information... Done
apt-transport-https is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
5.查看系統當前代號，其實這個無關緊要。
root@ubuntu02:~# lsb_release -c
Codename: trusty
root@ubuntu02:~#
6.添加docker 官方yum源。
root@ubuntu02:/etc/apt/sources.list.d# vi docker.listbr/>root@ubuntu02:/etc/apt/sources.list.d#
root@ubuntu02:/etc/apt/sources.list.d# cat docker.list
deb https://apt.dockerproject.org/repo ubuntu-trusty main
7.更新系統yum源配置，更新 apt 軟件包索引

root@ubuntu02:~#
上面有報錯，估計是https還需什麼配置，如果你做得沒有報錯的話，接下來可以用這個命令去安裝docker
#apt-get install -y docker-engine
我的有報錯，所有我使用了另外一個方法如下:
其實這是隻用了docker官方提供的腳本去安裝docker ，
可以看到它自動解決了上來那個更新yum的錯誤。
8.開始安裝當前最新版docker，也就是截止2017年12月19日最新版。

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:
sudo usermod -aG docker your-user
Remember that you will have to log out and back in for this to take effect!
WARNING: Adding a user to the "docker" group will grant the ability to run
containers which can be used to obtain root privileges on the
docker host.
Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
for more information.

9.檢查安裝結果：
root@ubuntu02:~# docker --version
Docker version 17.11.0-ce, build 1caf76c
10.啓動docker服務
root@ubuntu02:~# service docker start
docker start/running, process 9153
11.檢查docker 服務
root@ubuntu02:~# service docker status
docker start/running, process 9153
root@ubuntu02:~# ps -ef | grep docker

12.設置docker 開機自啓動
root@ubuntu02:~# update-rc.d docker start 20 2 3 4 5 . stop 20 0 1 6 .
Adding system startup for /etc/init.d/docker ...
/etc/rc0.d/K20docker -> ../init.d/docker

/etc/rc4.d/S20docker -> ../init.d/docker
/etc/rc5.d/S20docker -> ../init.d/docker
13.從docker hub 倉管中拉取下載一個CentOS鏡像
root@ubuntu02:~# docker pull centos
Using default tag: latest
latest: Pulling from library/centos
85432449fd0f: Downloading 46.48MB/73.43MB

Status: Downloaded newer image for centos:latest
14.檢查centos鏡像是否已經下載成功
root@ubuntu02:~# docker images centos
REPOSITORY TAG IMAGE ID CREATED SIZE
centos latest 3fa822599e10 2 weeks ago 204MB
15.進入centos 容器裏
root@ubuntu02:~# docker run -i -t centos /bin/bash
[root@0ab2ed6ba9f7 /]# df -h

上面結果表明已經成功。
後續會持續更新docker 高級實戰內容。
本人其實想寫一本書的。慢慢來吧。
