Dockerfile

#-----------------------------------------------------------------------------------------------------#   
# use the official Docker container
#
# official container 
#     * deploys the build from the apache.org downloads page
#     * does not come with the supporting tools to configure the webservice as in a Debian distribution
#     * make logs only accessible via the docker logs streams, so no persistence
# 
# This Docker configuration is a minor adaptation to the Official container setup. 
# Extra steps are in the layers for documenentation purpose
