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

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#
