Icinga2

This set of docker containers can be used to run Icinga2 - https://www.icinga.org/products/icinga-2/ The existing docker setups put several processes (like icinga2, icingaweb2, sometimes mysql) into one single container. I split these roles into several containers for better (re-)usability. It also makes it possible to run multiple icinga2 nodes + one single icingaweb2 interface.

The Icingaweb2 container also contains the director module - https://github.com/Icinga/icingaweb2-module-director

Please note that this setup and director are in alpha state, don't use for production.

Usage

Basic Usage

docker run --name my-mariadb -e MYSQL_ROOT_PASSWORD=my-secret -d mariadb docker run --name my-icinga2 -h icinga2 --link my-mariadb:mysql --restart=always -d rbicker/icinga2 docker run --name my-icingaweb2 -h icingaweb2 -v icinga2-config:/etc/icinga2 -v icinga2-lib:/var/lib/icinga2 --link my-mariadb:mysql --link my-icinga2:icinga2 -p 8080:80 -d rbicker/icingaweb2

Browse to http://localhost:8080 and log in using admin / admin

Docker-compose template

You can find a more complete template in the 'compose' directory.

File mysql.env:

MYSQL_ROOT_PASSWORD=icinga2

File icinga2.env:

MYSQL_ICINGA_PASSWORD=icinga2
MYSQL_ICINGA_USER=icinga2
MYSQL_ICINGA_DB=icinga2
API_USER=api
API_PASSWORD=api

File icingaweb2.env:

MYSQL_ICINGAWEB_DB=icingaweb2
MYSQL_ICINGAWEB_USER=icingaweb2
MYSQL_ICINGAWEB_PASSWORD=icingaweb2
MYSQL_DIRECTOR_DB=director
MYSQL_DIRECTOR_USER=director
MYSQL_DIRECTOR_PASSWORD=director

File docker-compose.yml:

version: '2'

services:
  mysql:
    image: mariadb
    env_file:
      - mysql.env

  icinga2:
    image: rbicker/icinga2
    hostname: icinga2
    links:
      - mysql
    env_file:
      - mysql.env
      - icinga2.env

  icingaweb2:
    image: rbicker/icingaweb2
    ports:
      - 8080:80
    env_file:
      - mysql.env
      - icinga2.env
      - icingaweb2.env
    links:
      - mysql
      - icinga2
    volumes:
      - ./icinga2-config:/etc/icinga2
      - ./icinga2-lib:/var/lib/icinga2

And just run docker-compose up -d and browse to http://localhost:8080, logging in using admin / admin
