# This script is run every time an instance of our app - aka grain - starts up.
# This is the entry point for your application both when a grain is first launched
# and when a grain resumes after being previously shut down.
#
# This script is responsible for launching everything your app needs to run. The
# thing it should do *last* is:
#
# * Start a process in the foreground listening on port 8000 for HTTP requests.
#
# This is how you indicate to the platform that your application is up and
# ready to receive requests. Often, this will be something like nginx serving
# static files and reverse proxying for some other dynamic backend service.
#
# Other things you probably want to do in this script include:
#
# * Building folder structures in /var. /var is the only non-tmpfs folder
# mounted read-write in the sandbox, and when a grain is first launched, it
# will start out empty. It will persist between runs of the same grain, but
# be unique per app instance. That is, two instances of the same app have
# separate instances of /var.
# * Preparing a database and running migrations. As your package changes
# over time and you release updates, you will need to deal with migrating
# data from previous schema versions to new ones, since users should not have
# to think about such things.
# * Launching other daemons your app needs (e.g. mysqld, redis-server, etc.)
