Dockerfile

# This Dockerfile defines how to build container images containing a
# *development* version of Exchange. It really isn't usable for production, and
# it isn't meant to be; it's for the benefit of people hacking on Exchange.

# The django app is tested on CentOS 6.7 to match client production environment
FROM centos:6.7

# Prevent yum from invalidating cache every build (default is keepcache=0).
# Pull in initial updates, e.g. security updates
# Install the packages we want for the application
# ... and do one big step to avoid creating extra layers uselessly
# TODO: audit what is needed here or not
