Since commit 658e20f, the template makes the assumption that the container running docker-gen is the container running nginx while checking that upstream containers are reachable.
By introducint the `NGINX_CONTAINER` environment variable, users are now able to indicate which container is actually running nginx when running docker-gen and nginx in separated containers.

# In this compose file we define a dockergen container which is running the docker-gen process with the
|
|
# `-only-exposed` option. This should not be an issue since the template for the nginx config file should only
|
|
# have to deal with upstream containers which are required to have at least one port exposed, and since the nginx
|
|
# container with no exposed port makes no sense.
