Ubuntu下Docker CE的安装

本文用于记录Ubuntu 17.10下Docker CE的安装。

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

添加GPG key

使用如下命令添加docker官方的GPG key，

命令：curl -fsSL https://download.docker.com/linux/ubuntu/gpg | 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) <docker@docker.com>
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] https://download.docker.com/linux/ubuntu $(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
