Subject Re: [DISCUSSION] Karaf docker.io

I love it ! Is it production ready ?… uh wait docker is not :) 

More seriously, between this and karaf-boot I think that the story in terms of starting to
deploying a project can really be improved greatly. We could then even push the docker images
to a docker repository.

That way you can launch Docker Unomi instances in a large cluster with just a few CLI instructions

to create "business oriented" Karaf (based on the first point). For instance, you want a Karaf
WebContainer, Karaf Hibernate, just use docker:create command to create a custom Karaf distribution
in a docker image, this distribution will have "pre-installed/bootFeatures" as you described
in the shell command.
