nagios-nrpe-server running on docker

• Use env var to set your nagios server. -e "NAGIOS_SERVER=10.0.0.1"
• Mount your own config files into the container. -v /srv/nrpe-server/nrpe.d:/etc/nagios/nrpe.d
• Use the docker checks. -v /var/run/docker.sock:/var/run/docker.sock

For example:

#Normal - load/disk/mem checks
docker run -d --name nrpe-server -p 5666:5666 -e "NAGIOS_SERVER=10.0.0.1" mabitt/nrpe-server

#Enable docker checks
docker run -d --name nrpe-server -p 5666:5666 -v /var/run/docker.sock:/var/run/docker.sock -e "NAGIOS_SERVER=0.0.0.0" mabitt/nrpe-server
