# This is a systemd file to run this docker container under systemd.
# To make this work:
#  * pull the image (probably from ops docker registry)
#  * place this file in /etc/systemd/system without the .systemd extension
#  * run the commands:
#  systemctl daemon-reload
#  systemctl enable oso-rhel7-host-monitoring
#  systemctl start oso-rhel7-host-monitoring

# mwoodson note 1-7-16:
# pcp recommends mounting /run in their Dockerfile
#  /run conflicts with cron which also runs in this container.
# I am leaving /run out for now.  the guys in #pcp said that they mounted /run
#  to shared the pcp socket that is created in /run. We are not using this,
#  as far as I know.
#  This problem goes away with systemd being run in the containers and not using
#   cron but using systemd timers
