Docker

Install Docker

For Ubuntu14.04

sudo apt-get install docker.io

Ubuntu 16.04 預設就會裝了

Start Docker

Run docker daemon

service docker start

不想每次都要加sudo，可以照下面步驟設定

sudo usermod -aG docker {USER}
newgrp docker
service docker restart

希望開機預設喚起docker daemon

將"service docker start"加入到/etc/rc.local

常用指令

docker images                             //list all images
docker inspect <container id>             //lookup container infomation
docker ps                                 //list running container
docker ps -a                              //list all container
docker rm <container id>                  //remove container
docker rmi <image id>                     //remove image
docker start/stop <container id>          //start/stop a container
docker run --rm <image name or image id>  //run image as container and auto remove conatiner when exit container
docker run -idt <image name or image id>  //create and run image as container in background
docker exec -it <container id> /bin/bash  //attach into container
  1. 如果不是以daemon方式跑起container，那在執行完CMD後就會自動結束
