在AWS EC2的实例(Ubuntu)里面安装docker时,使用一般的安装步骤docker
:~$ sudo apt-get update
:~$ sudo apt-get install docker
安装完成以后,查看docker版本时,提示docker命令不存在ubuntu
:~$ sudo docker -v
sudo: docker: command not found
在stack overflow上看人说,使用apt-get 安装的是一个GUI应用程序,而不是咱们要使用的开发工具。经过运行以下脚原本安装dockercurl
sudo curl -sSL https://get.docker.com/ | sh
在安装完成后,要注意下面的提示:工具
WARNING: Adding a user to the "docker" group will grant the ability to run containers which can be used to obtain root privileges on the docker host. Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface for more information.
而后更新docker run命令开发工具
sudo apt-get update && apt-get upgrade
最后,查看docker版本:ui
:~$ sudo docker --version Docker version 1.13.1, build 092cba3
说明docker已经安装成功url
替换docker,使用docker.iospa
sudo apt-get install docker.io
