  首先,因为国内的网络的限制。我们这里优先选择阿里云的镜像,而非docker官方的镜像进行安装以保证国内用户的使用。
step 1: 安装必要的一些系统工具
sudo apt-get update
sudo apt-get -y install apt-transport-https ca-certificates curl software-properties-common
# step 2: 安装GPG证书
curl -fsSL http://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -
# Step 3: 写入软件源信息
sudo add-apt-repository "deb [arch=amd64] http://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable"
# Step 4: 更新并安装Docker-CE
sudo apt-get -y update
sudo apt-get -y install docker-ce
# 安装指定版本的Docker-CE:
# Step 1: 查找Docker-CE的版本:
# apt-cache madison docker-ce
# docker-ce | 17.09.1~ce-0~ubuntu-xenial | http://mirrors.aliyun.com/docker-ce/linux/ubuntu xenial/stable amd64 Packages
# docker-ce | 17.09.0~ce-0~ubuntu-xenial | http://mirrors.aliyun.com/docker-ce/linux/ubuntu xenial/stable amd64 Packages
# Step 2: 安装指定版本的Docker-CE: (VERSION例如上面的17.09.0~ce-0~ubuntu-xenial)
# sudo apt-get -y install docker-ce=[VERSION]
若安装完成,输入docker run hello-world命令后会有以下现象:
root@ubuntu:/home/ubuntu# docker run hello-world
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
