Daemon that helps you monitor docker containers with tools like monit by maintaining PID files for the containers. I use this for replylater.com and it's not very polished yet but maybe some people will find it useful.

docker-monit: very simple daemon that helps you monitor docker containers by maintaining PID files for them.

Create file /etc/default/docker-monit with contents:

CONTAINERS="container1 container2 container3"

Then run:

cp docker-monit /usr/local/bin/

Upstart users

cp docker-monit.conf /etc/init

start docker-monit

stop docker-monit

sudo cat /var/log/upstart/docker-monit.log

Systemd users

cp docker-monit.service /etc/systemd/service

/bin/systemctl enable docker-monit.service

service start docker-monit

service stop docker-monit

sudo journalctl -f -u docker-monit.service

Monit users

Create file /etc/monit/conf.d/docker-monit with contents:

check process docker-monit with pidfile /var/run/docker-monit.pid
  start program = "/sbin/start docker-monit"
  stop program = "/sbin/stop docker-monit"
  if 5 restarts with 5 cycles then timeout

check process rl_db with path /var/run/docker-monit/rl_db.pid
  if 5 restarts with 5 cycles then timeout
