##
# How to use this file:
#
# Change these settings:
#    VIRTUAL_HOST
#    LETSENCRYPT_HOST
#    LETSENCRYPT_EMAIL
#
# Copy Allura/production-docker-example.ini to /allura-data/production.ini and review its contents,
#  making changes as appropriate
#
# In comparision to the development version of docker-compose.yml, this production ready version:
#  * only exposes ports that are necessary, limiting them to within docker, or to 127.0.0.1
#  * sets containers to always restart
#  * has an nginx proxy to provide HTTPS via letsencrypt.  May take a little time to configure itself
#  * has no debugging "outmail" container, emails should go out into the real world
#  * git-http container serves git and also proxies back to the "web" container
