Dockerfile

# WARNING: this Docker file is not tested with the current askbot-setup script.

#
#----------------------------------------------------
# This Dockerifle builds a simple Askbot installation
#
# It makes use of environment variables:
# 1. DATABASE_URL See https://github.com/kennethreitz/dj-database-url for details
# 2. SECRET_KEY for making hashes within Django.
# 3. ADMIN_PASSWORD used for creating a user named "admin"
# 4. NO_CRON set this to "yes" to disable the embedded cron job.
#
# Make sure to *+always* start the container with the same SECRET_KEY.
#
# Start with something like
#
# docker run -e 'DATABASE_URL=sqlite:////askbot-site/askbot.db' -e "SECRET_KEY=$(openssl rand 14 | base64)" -e ADMIN_PASSWORD=admin -p 8080:80 askbot/askbot:latest
#
# User uploads are stored in **/askbot_site/askbot/upfiles** . I'd recommend to make it a kubernetes volume.
