What is cdist trigger server¶

The cdist trigger server can be used for autonomous configuration of hosts. Unlike the "normal" procedure of cdist, where a human being or a control server itself starts cdist for the configuration, the cdist trigger server waits until it gets triggered (therefore the name) by a host which wants to be configured.

The trigger server takes the IP from the requester and first tries to resolve the IP to a FQDN (via the reverse zone). The FQDN (or the IP if reverse lookup didn't work out) is then used for the cdist configuration (same as cdist config HOSTNAME)

Where do we use it¶

We at ungleich, we use the cdist trigger server currently for our server startup chain (See: The ungleich server OS setup
Where the netbooted server will trigger the trigger server and then gets fully configured.

How to get¶

Cdist trigger server is currently in beta phase. This means you have to clone the repository ("cdist":github.com:ungleich/cdist.git) and checkout the beta branch

git clone git@github.com:ungleich/cdist.git
cd cdist
git checkout beta

How to configure¶

The simplest usage is the following

cdist trigger -b -H 3000 --ipv6

This will start the server, listen on port 3000 and also enable IPv6

Nice additional configurations¶
