redash/setup/ubuntu/bootstrap.sh

#!/bin/bash
#
# This script setups Redash along with supervisor, nginx, PostgreSQL and Redis. It was written to be used on 
# Ubuntu 16.04. Technically it can work with other Ubuntu versions, but you might get non compatible versions
# of PostgreSQL, Redis and maybe some other dependencies.
#
# This script is not idempotent and if it stops in the middle, you can't just run it again. You should either 
# understand what parts of it to exclude or just start over on a new VM (assuming you're using a VM).
