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 -mx86_64devops@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 -csartfuldevops@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 -mx86_64devops@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 updatehit: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... doneroot@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 -okroot@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 0ebfcd88pub  rsa4096 2017-02-22 [scea]   9dc8 5822 9fc7 dd38 854a e2d8 8d81 803c 0ebf cd88uid      [ 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 updatehit: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... doneroot@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 packagesroot@ubuntu:/home/devops#root@ubuntu:/home/devops# apt-get install docker-ce=17.12.1~ce-0~ubuntureading package lists... donebuilding dependency tree    reading state information... donedocker-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
