icinga2

This repository contains the source for the icinga2 docker image.

It is only the client side. When used inside a privileged container, you'll be able to monitor the whole machine with this image.

For the master node consult @jjethwa's docker image.

This image automatically configures the Icinga client up with the master Icinga node, using the provided API credentials.

Recommended execution is via docker-compose. There is too much stuff which has to be configured outside the container to run it via plain docker run but of course, it would be possible.

wget https://raw.githubusercontent.com/adamdelman/icinga2-client-docker/master/docker-compose.yml
$EDITOR docker-compose.yml
docker-compose up
