Docker Java 8 helloworld

Example Docker image that when echos "Hello world!" when run.

Image has JRE rather than JDK to limit installed components. Tested on Mac using Boot2Docker (v1.5.0).

Requires:

• Docker
• Boot2Docker
• JDK (to compile java file locally)

To run:

# compile class
javac helloworld.java

# build image
docker build -t java8-helloworld .

# run image
docker run -it --rm --name my-running-app java8-helloworld
