A Docker image for running enRoute OSGi framework?

Question

I want to try and run enRoute inside a Docker container but cannot seem to find any Docker images. Can anyone suggest the location of an image?

Answer 1

OSGi enRoute uses Bndtools. There you can export an bndrun file to an executable JAR (see the Base Tutorial and especially deploying). You therefore only need to have a Java 8 image. This is a non-trivial task because Oracle is rather annoying concerning their copyrights but there is on ggtools/java8 image. Therefore, to run an OSGi enRoute executable JAR on Docker, you can use the following Dockerfile:

FROM                            ggtools/java8
MAINTAINER                      [email protected]
CMD                             java -jar test.jar
ADD                             test.jar test.jar

You can then build and run as follows:

$ ls
Dockerfile  
test.jar          
$ docker build .
$ docker images

If this works for you then an Application note for the OSGi enRoute website would be highly appreciated.
