abtrigger

#!/bin/bash

# This is a simple cron job to serve as an autobuild trigger.
# This is meant to run as a cron job every five minutes, and
# will trigger the build system based on a trigger file.
# If the trigger file contains a list of routers, it will
# run that list. Otherwise, it will trigger a full catalog
# build.

# This trigger system is meant to be used with autobuild when
# running on a standalone bare-metal system. For use within
# the docker-rooterbuilder system, use abtrigger.docker as a
# wrapper for this script instead of trying to set up cron
# within a docker container.

######
#
# IMPORTANT: you MUST edit the following line to point to the
# config file you want to use for this instance of the script.
#
source /build/autobuild/autobuild19.conf
