Built a simple SpringBoot project in Docker .

• first of all , you need to star the project , than download and run Docker on your local system .

  My local operation system is MacOS

  For how to use Docker on Mac , plz read My blog : MacOS安装Docker

• built project by run command :

    docker build -t docker-demo ../docker-demo 
  

• start project by run command :

    docker run -d -p 8080:8080 docker-demo
  

  than you can see this in your docker pannel:

  

• open your browser and visite :

    http://127.0.0.1:8080
  

• You can view Dockerfile's syntax in here.

  And this is quite necessary .
