Configuration of Automatron is fairly simple and contained within a single file;
This guide will walk through configuring a basic Automatron instance.
The fastest method to configure Automatron is to start with the example configuration file
config/config.yml.example. This configuration file contains basic default values which can be used in most implementations of Automatron. To use this file we can simply rename it to the default Automatron configuration file
$ cp config/config.yml.example config/config.yml
Once complete, we can now start customizing our configuration file.
Automatron relies on SSH to perform both health checks and actions. Within
config.yml there is an SSH section which will allow us to define the necessary SSH details such as;
user to authenticate as, a
gateway or "jump server" for SSH connections and a Private SSH
ssh: # SSH Configuration user: root gateway: False key: | -----BEGIN RSA PRIVATE KEY----- this is an example -----END RSA PRIVATE KEY-----
gateway setting is left as
False Automatron will login to each host directly. To specify a "jump server" simply specify the DNS or IP address of the desired server.
At this time Automatron does not support using sudo or other privilege escalation tools. Any checks or actions will be performed via the user privileges specified in
Enable Auto Discovery¶
By default, Automatron will listen on port
9000 for any HTTP requests. When an HTTP request is made to Automatron the IP will be captured and that server will then be identified as a monitoring target.
There are several plugins that enable other methods for host discovery, in this section we will also enable the
roster discovery plugin. This configuration is within the
discovery section of the
discovery: upload_path: /tmp/ vetting_interval: 30 plugins: # Web Service for HTTP PINGs webping: ip: 0.0.0.0 port: 9000
To enable the
roster plugin we simply need to append the
roster configuration within the
discovery: upload_path: /tmp/ vetting_interval: 30 plugins: # Web Service for HTTP PINGs webping: ip: 0.0.0.0 port: 9000 # Roster Discovery roster: hosts: - 10.0.0.1
Each plugin has unique configuration details, additional discovery plugins can be found in the Automatron Plugins project.
At this point Automatron has been configured. We can now move on to creating our own Runbooks.
