DockerFile to run a java program

Question

Hi I\'m new to Docker and trying out to write a new image from the scratch. I am writing this dockerFile to compile and run a simple java program available in the same directory

Another way...

1. you have to use "java:8" as base image or install jdk on "ubuntu" image.

2. build the image

   docker build -t imagename .
   

3. run it(mounting Helloworld.java to container)

   docker run -it -v ~/system-path:/javafolder imagename
   

type these commands to execute inside container-

cd javafolder

javac HelloWorld.java

java HelloWorld
