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
再次使用apt-get update更新源中的软件列表
