Ubuntu 安装Docker

参考：官网

安装依赖包：

$ sudo apt-get update

$ sudo apt-get install -y --no-install-recommends 
    linux-image-extra-$(uname -r) 
    linux-image-extra-virtual

Install using the repository

1.Install packages to allow apt to use a repository over HTTPS:

sudo apt-get install -y --no-install-recommends 
    apt-transport-https 
    ca-certificates 
    curl 
    software-properties-common

2.Add Docker’s official GPG key:

curl -fsSL https://apt.dockerproject.org/gpg | sudo apt-key add -

Verify that the key ID is 58118E89F3A912897C070ADBF76221572C52609D.

apt-key fingerprint 58118E89F3A912897C070ADBF76221572C52609D

pub   4096R/2C52609D 2015-07-14
      Key fingerprint = 5811 8E89 F3A9 1289 7C07  0ADB F762 2157 2C52 609D
uid                  Docker Release Tool (releasedocker) <docker@docker.com>

3.Use the following command to set up the stable repository.

sudo add-apt-repository 
       "deb https://apt.dockerproject.org/repo/ 
       ubuntu-$(lsb_release -cs) 
       main"

4.Install Docker

sudo apt-get update

sudo apt-get -y install docker-engine

5.Verify Docker

root@ubuntu:/home/wasdns# docker -v
Docker version 1.13.1, build 092cba3

sudo 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.
 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
