# This Ansible playbook configures mirroring in and out of Gerrit.
#
# To run it, use:
#   ansible-playbook -i hosts baserock_gerrit/instance-mirroring-config.yml
#
# It expects the SSH key for the 'lorry' user to exist at
# ../keys/lorry-gerrit.key.
#
# This script currently doesn't handle the lorry-controller.conf file that
# controls what lorry-controller mirrors into Gerrit. To set up or modify
# lorry-controller configuration you need to commit your changes to the
# 'local-config/lorries' project on the Gerrit.
