docker学习

docker作为去年比较火的一款快速部署工具，正好最近闲来无事就去学习饿了下

首先是安装docker

sudo apt-get install apt-transport-https 

 sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9 

vi /etc/apt/sources.list.d/docker.list

     deb https://apt.dockerproject.org/repo ubuntu-xenial main

sudo apt-get update

sudo apt install lxc-docker

安装完后尝试启动docker

sudo service docker start

在执行docker  info

sudo docker info

若输出如上面列表则安装成功

然后去下载镜像

sudo docker pull ubuntu:14.04

示例下载ubuntu 14.04的镜像

然后运行他

sudo docker run -i -t ubutnu:14.04 /bin/sbin

若要后台运行则加上参数-d

运行后就对他进行配置跟ubuntu 14.04 的配置一致   http://blog.csdn.net/qq_30371793/article/details/50387589

配置完成后退出docker

然后去 hub.docker.com 注册用户登陆并创建库

创建完成后在终端里面登陆docker账号

sudo docker login

并输入账号密码

登陆完成后将镜像加入后台运行

然后去提交容器到自己的docker 库

sudo docker commit 运行时的容器id 账号/库名:tag名

sudo docker push账号/库名:tag名
