Docker Open Monitoring Distribution (OMD)

This is a Dockerfile to set up the Open Monitoring Distribution along with Msmtp send-only mail (using Gmail, Mandrill, etc.) for notifications.

Build

If your site requires OMD to run with tmpfs, remove the line in start.sh that disables it, then run the container with either --priviliged or --cap-add SYS_ADMIN.

Build from Dockerfile:

docker build -t omd .

Create data-only volume. OMD site configurations will be auto-generated in /opt/omd/sites.

docker run -v /opt/omd/sites -v /config --name omd_config debian:jessie

Edit the msmtprc and msmtp-aliases files with your email SMTP info. Default site/user is omd. Then:

docker cp msmtprc omd_config:/config/
docker cp msmtp-aliases omd_config:/config/

Run

Systemd service file is also available.

docker run -d --volumes-from omd_config -v /etc/localtime:/etc/localtime -p 5000:5000 --name omd_run omd

Be patient when starting (20-40 seconds). The site has to be generated initially, then regenerated on subsequent runs to make sure all the permissions and user/groups are correct. Existing site info will not be overwritten!

Manage

The default site name is 'default'. You can use the omd commands to control that site:

$ docker exec -it omd_run /bin/bash
# omd --help
# omd su default
OMD[defatul]:~$ ....
