安装依赖
关于docker ce版本在ubuntu下安装有如下限制
64位的os
需要ubuntu64bit的os, 确认方法如下
devops@ubuntu:~$ uname -m x86_64 devops@ubuntu:~$
版本
支持如下ubuntu的版本
artful 17.10
xenial 16.04 (lts)
trusty 14.04 (lts)
注意:其中artful 17.10只支持docker ce17.11 edge以及以后版本,因为artful本身也是在2017年10月发行的过渡版本
发行代码的确认方式,比如artful
devops@ubuntu:~$ lsb_release -cs artful devops@ubuntu:~$
硬件
ubuntu对docker ce的支持除了需要是64位的os之外,x86的cpu也是需要的。除了x86之外,还有如下的支持类型
armhf
s390x(ibm z)
ppc64le (ibm power)
devops@ubuntu:~$ uname -m x86_64 devops@ubuntu:~$
安装
apt-get update
使用apt-get update更新源中的软件列表
devops@ubuntu:~$ sudo su [sudo] password for devops: root@ubuntu:/home/devops# apt-get update hit:1 http://cn.archive.ubuntu.com/ubuntu artful inrelease get:2 http://cn.archive.ubuntu.com/ubuntu artful-updates inrelease [78.6 kb] hit:3 http://cn.archive.ubuntu.com/ubuntu artful-backports inrelease get:4 http://security.ubuntu.com/ubuntu artful-security inrelease [78.6 kb] get:5 http://cn.archive.ubuntu.com/ubuntu artful-updates/main i386 packages [212 kb] get:6 http://cn.archive.ubuntu.com/ubuntu artful-updates/main amd64 packages [216 kb] get:7 http://cn.archive.ubuntu.com/ubuntu artful-updates/universe i386 packages [89.0 kb] get:8 http://cn.archive.ubuntu.com/ubuntu artful-updates/universe amd64 packages [89.9 kb] fetched 764 kb in 4s (163 kb/s) reading package lists... done root@ubuntu:/home/devops#
安装所需的package
命令:apt-get install apt-transport-https ca-certificates curl software-properties-common
执行日志

添加gpg key
使用如下命令添加docker官方的gpg key,
命令:curl -fssl | sudo apt-key add -
执行日志
root@ubuntu:/home/devops# curl -fssl https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add - ok root@ubuntu:/home/devops#
此key的数字签名为9dc8 5822 9fc7 dd38 854a e2d8 8d81 803c 0ebf cd88,所以可以用其最后8位进行确认
root@ubuntu:/home/devops# apt-key fingerprint 0ebfcd88 pub rsa4096 2017-02-22 [scea] 9dc8 5822 9fc7 dd38 854a e2d8 8d81 803c 0ebf cd88 uid [ unknown] docker release (ce deb)sub rsa4096 2017-02-22 [s] root@ubuntu:/home/devops#
设定stable源仓库
使用如下命令设定x86安装类型的stable源仓库
命令:add-apt-repository “deb [arch=amd64] $(lsb_release -cs) stable”
如果是其他类型的化,对应关系参看如下,将上述命令中的arch=amd64进行替换即可
执行日志:
root@ubuntu:/home/devops# add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" root@ubuntu:/home/devops#
apt-get update
再次使用apt-get update更新源中的软件列表
root@ubuntu:/home/devops# apt-get update hit:1 http://cn.archive.ubuntu.com/ubuntu artful inrelease get:2 http://security.ubuntu.com/ubuntu artful-security inrelease [78.6 kb] get:3 http://cn.archive.ubuntu.com/ubuntu artful-updates inrelease [78.6 kb] hit:4 http://cn.archive.ubuntu.com/ubuntu artful-backports inrelease get:5 https://download.docker.com/linux/ubuntu artful inrelease [51.9 kb] get:6 https://download.docker.com/linux/ubuntu artful/stable amd64 packages [1462 b] fetched 211 kb in 2s (85.8 kb/s) reading package lists... done root@ubuntu:/home/devops#

指定版本安装
如果希望指定版本方式安装,则在安装时需要指定docker-ce=17.12.1~ce-0~ubuntu版本方式即可
root@ubuntu:/home/devops# apt-cache madison docker-ce docker-ce | 17.12.1~ce-0~ubuntu | https://download.docker.com/linux/ubuntu artful/stable amd64 packages docker-ce | 17.12.0~ce-0~ubuntu | https://download.docker.com/linux/ubuntu artful/stable amd64 packages root@ubuntu:/home/devops# root@ubuntu:/home/devops# apt-get install docker-ce=17.12.1~ce-0~ubuntu reading package lists... done building dependency tree reading state information... done docker-ce is already the newest version (17.12.1~ce-0~ubuntu). 0 upgraded, 0 newly installed, 0 to remove and 53 not upgraded. root@ubuntu:/home/devops#
安装后确认
版本确认
