What about a generate-docker-file command ? 

He was thinking it would be cool to have a "generate docker file" command that would create a Dockerfile like : 

```
FROM fabric8/java-jboss-openjdk8-jdk:1.0.10

ENV JAVA_APP_JAR hello-swarm.jar
ENV AB_JOLOKIA_OFF true

EXPOSE 8080

ADD target/hello-swarm.jar /app/

```
