How to use this image
=======================

Start a Java instance in your app

The most straightforward way to use this image is to use a Java container 
as both the build and runtime environment. 
In your Dockerfile, writing something along the lines of the following 
will compile and run your project:

::

	FROM openjdk:7
	COPY . /usr/src/myapp
	WORKDIR /usr/src/myapp
	RUN javac Main.java
	CMD ["java", "Main"]

You can then run and build the Docker image:

::

	$ docker build -t my-java-app .
	$ docker run -it --rm --name my-running-app my-java-app
