This is done by intruducing a new VIRTUAL_PROTO=static. The VIRTUAL_ROOT variable points to the static root which should be mounted into the container as volume. Often the container of the static website does not need to run, so I introduced a new environment variable INCLUDE_STOPPED_CONTAINERS that adds the -include-stopped flag to docker-gen
This changes the base-image to the official nginx image,
reducing the virtual size of the image by approx 50%.
