docker

参考自这里

1 安装docker

查看发行情况:lsb_release -a,返回如下:

Distributor ID:	Ubuntu
Description:	Ubuntu 18.04.4 LTS
Release:	18.04
Codename:	bionic

其中bionic就是代号。下面以官方代码库的方式安装,也可以直接从ubuntu的repository里直接安装。

sudo apt-get install apt-transport-https ca-certificates

sudo apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D

echo "deb https://apt.dockerproject.org/repo ubuntu-bionic main" | sudo tee /etc/apt/sources.list.d/docker.list

后来发现这个源有误,只要删除文件sudo rm -f /etc/apt/sources.list.d/docker.list再执行更新sudo apt-get update即可, 如果还不行,编辑一下文件:/etc/apt/sources.list

靠谱的办法是,参考自这里

(1)添加gpg key:curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

(2)添加源:sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable", 上述源文件末尾会新增一行。

验证:sudo docker version,内容如下:
