# icinga-satellite
|
|
An easy-to-use Dockerized Icinga2 satellite setup. It could be used as an
|
|
Icinga2 agent aswell, but I don't think that would make much sense. The goal
|
|
is instead to create an easy-to-deploy satellite image.

|
|
* [0.1-alpine](https://github.com/jackbenny/icinga-satellite/blob/0.1-alpine/Dockerfile)
|
|
|
|
> **NOTE:** Currently there are some problems with the Alpine image.
|
|
> Use the *main images* instead, tagged *0.n*.
|
|
|
|
There are two available images for you to choose from. The main images (0.*n*) are based on
|
|
Debian 10-slim from tag 0.5 and up. Previous to 0.5 they were based on Ubuntu 18.04.
|
|
The main images uses Icinga2 from Icingas official repository.
|
|
|
|
The other images (0.*n*-alpine) are based on Alpine with Icinga2 from Alpines repository.
|
|
From 0.1.1-alpine and up, the Alpine images are built on the latest Alpine image. Previous to
|
|
0.1.1 they were based on Alpine 3.11.
|
|
|
|
## Environment variables
|
|
Everything is controlled using the following environment variables.
|
|
|
|
* **CN** is the Common Name of the satellite
|
|
* **ZONE** is the zone in which this satellite should be in. If no zone is specified
|
|
it defaults to using the **CN** as the zone.
|
|
* **PARENTCN** is the Common Name of the parent host, for example the master. If
|
|
no **PARENTCN** is specified it defaults to using the **PARENTHOST** as a
|
|
**PARENTCN**
|
|
* **PARENTHOST** is the FQDN or IP of the parent host, for example the master.
|
|
* **PARENTPORT** is the Icinga2 port on the parent host. Defaults to 5665.
|
|
* **TICKET** is the ticket you get from the master (if you are using Director
|
|
you find it under the Agent tab of the host).
|
|
* **ACCEPT_CONFIG** takes a ***y*** or ***n*** value for yes or no. The default is
|
|
***n***
|
|
* **ACCEPT_COMMANDS** takes a ***y*** or ***n*** value for yes or no. The default is
|
|
***n***
|
|
* **DISABLE_CONFD** takes a ***y*** or ***n*** value for yes or no. The default is
|
|
***y***. This should be a sane default for most people.
|
|
* **LOCAL_TIMEZONE** sets the local timezone of the satellite. For example
|
|
*Europe/Stockholm* or *America/New_York*
|
|
|
|
