be done for you.

docker images directly in Karaf). I would like to add a new set of features in karaf-docker:
be able 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.

a new dimension.
