# Synchronizes files in /tmp/staging between remote hosts
# The following variables need to be supplied with the
# --extra-vars flag for the playbook to work:
# 'remote_src_host', 'remote_dest_host'
#
# Example:
# ansible-playbook sync-hosts.yml --extra-vars \
#   "remote_src_host=bodhi-backend01.iad2.fedoraproject.org \
#   remote_dest_host=sundries01.iad2.fedoraproject.org"
