should we have an nginx container included? maybe just instructions on how to include one

ARG should be used for sensitive variables so as to keep the values of these variables 
out of the build and hence will not show with an "inspect image" command

Do we pre-build a CKAN image and use that (and extend) as the base image OR 
    just build it from scratch and while saving to storage what we need to

Use a bind mount for the config file (ckan.ini)
  mkdir local
  docker cp ckan:/srv/app/ckan.ini ./local/ckan.ini
  docker cp ckan:/srv/app/src ./local/src
  stop/remove ckan container
  docker run -p 0.0.0.0:5000:5000 --net ckan-docker_default --hostname ckan --name ckan \
      --env-file=./environ --mount type=bind,source=$(pwd)/local/ckan.ini,target=/srv/app/ckan.ini \
      --mount type=bind,source=$(pwd)/local/src,target=/srv/app/src \
      -d ckan-docker_ckan

Maybe include a script to replace docker-compose if required
