docker tutorial

$sudo pacman -S docker

$sudo systemctl enable docker && sudo systemctl start docker

$docker pull daocloud.io/ubuntu:14.04

docker images  //show all images

docker commit 2e6f  myubuntu //create img based on '2e6f' container

docker   rmi   myubuntu  //remove image

docker ps  //show running containers

docker ps -a //show all containers

docker rm 2ef6    //remove container

docker rm `docker ps -a`  //remove all containers

Start an interactive container

$docker run -t -i daocloud.io/ubuntu:14.04 /bin/bash

暴露端口

docker run --name mynginx-container -d -p 8080:80 nginx-image

这样启动，您就可以通过http://localhost:8080 或者 http://宿主 IP:8080 访问 Nginx 了。
