**前言：**

docker官网有很详细的安装教程，建议按照官网的步骤进行安装。

Install Docker on Ubuntu：[https://docs.docker.com/engine/installation/linux/ubuntulinux/][https_docs.docker.com_engine_installation_linux_ubuntulinux]

docker需要3.10或者更高版本的内核支持，通过**uname -r**查看内核版本。

**步一：更新apt源**

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

**步二：添加新的GPG密钥**

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

**步三：通过lsb\_release -a命令查看系统的版本，Ubuntu14.04**

Trusty 14.04 (LTS) 	deb https://apt.dockerproject.org/repo ubuntu-trusty main

**步四：设置源**

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

**步五：更新APT**

$ sudo apt-get update

**步六：确认APT已经更新，正常会输出结果**

$ apt-cache policy docker-engine
    
      docker-engine:
        Installed: 1.12.2-0~trusty
        Candidate: 1.12.2-0~trusty
        Version table:
       *** 1.12.2-0~trusty 0
              500 https://apt.dockerproject.org/repo/ ubuntu-trusty/main amd64 Packages
              100 /var/lib/dpkg/status
           1.12.1-0~trusty 0
              500 https://apt.dockerproject.org/repo/ ubuntu-trusty/main amd64 Packages
           1.12.0-0~trusty 0
              500 https://apt.dockerproject.org/repo/ ubuntu-trusty/main amd64 Packages

**步七：再次更新源**

$ sudo apt-get update

**步八：安装增强包**

$ sudo apt-get install linux-image-extra-$(uname -r) linux-image-extra-virtual

**步九：再次更新源**

$ sudo apt-get update

**步十：安装Docker**

$ sudo apt-get install docker-engine

**步十一：启动Docker守护进程**

$ sudo service docker start

**步十二：确认安装成功，这个命令会下载一个测试镜像。**

$ sudo docker run hello-world

**看到这个界面意味着成功了：**

$ docker run hello-world
     Unable to find image 'hello-world:latest' locally
     latest: Pulling from library/hello-world
     535020c3e8ad: Pull complete
     af340544ed62: Pull complete
     Digest: sha256:a68868bfe696c00866942e8f5ca39e3e31b79c1e50feaee4ce5e28df2f051d5c
     Status: Downloaded newer image for hello-world:latest
    
     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 Engine CLI client contacted the Docker Engine daemon.
     2. The Docker Engine daemon pulled the "hello-world" image from the Docker Hub.
     3. The Docker Engine daemon created a new container from that image which runs the
        executable that produces the output you are currently reading.
     4. The Docker Engine daemon streamed that output to the Docker Engine CLI client, which sent it
        to your terminal.
    
     To try something more ambitious, you can run an Ubuntu container with:
     $ docker run -it ubuntu bash
    
     Share images, automate workflows, and more with a free Docker Hub account:
     https://hub.docker.com

**步十三：查看所有的容器**

$ docker ps -a
