ubuntu16.04 docker安装

docker官网安装页面：https://docs.docker.com/engine/installation/linux/ubuntu/

这个是ubuntu14.04 LTS需要的

$ sudo apt-get update

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

下面开始安装

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

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

#Verify that the key ID is 58118E89F3A912897C070ADBF76221572C52609D.
$ apt-key fingerprint 58118E89F3A912897C070ADBF76221572C52609D

        Key fingerprint = 5811 8E89 F3A9 1289 7C07  0ADB F762 2157 2C52 609D
  uid                  Docker Release Tool (releasedocker) <docker@docker.com>

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

$ sudo apt-get update

$ sudo apt-get -y install docker-engine
# 或者
$ sudo apt-get -y install docker-engine=<VERSION_STRING>

下面是测试是否成功

$ sudo docker run hello-world

安装成功后pull镜像会非常慢，配置加速器

$ sudo vim /lib/systemd/system/docker.service 

找到

ExecStart=/usr/bin/dockerd -H fd://

修改成

ExecStart=/usr/bin/dockerd -H fd:// --registry-mirror=https://ulh1xo4t.mirror.aliyuncs.com

 使配置生效

sudo systemctl daemon-reload 
sudo systemctl restart docker

卸载：

$ sudo apt-get purge docker-engine
$ sudo rm -rf /var/lib/docker

其他编写的配置文件需要手动删除
