1. Create a Thin WAR Java EE project. Name it "micro".
2. Create a Dockerfile in project folder with the following content:

               
               FROM airhacks/wildfly
               COPY ./target/micro.war ${DEPLOYMENT_DIR}                
               
           

   Also airhacks/payara, airhacks/tomee images are available from https://hub.docker.com/u/airhacks/. The docker files are maintained in https://github.com/AdamBien/docklands.

3. Perform build from project folder: mvn package && docker build -t airhacks/micro .
4. Run the project: docker run -d -p 8080:8080 --name micro airhacks/micro

Behind the scenes:

1. CentOS 7, JDK 1.8, the chosen application server (WildFly, Payara, TomEE) is going to be downloaded the first time (~560 MB, see https://youtu.be/hoqJdH87e7g) from https://hub.docker.com/u/airhacks/.
2. All subsequent builds will only rebuild the Thin WAR -- it will take milliseconds. The smaller the WAR, the higher the productivity: https://youtu.be/5N4EUDhrkec
