h1. How to configure servers with cdist

h2. Introduction

We are using "cdist":https://www.nico.schottelius.org/software/cdist/ to manage our system configurations.

h2. Applying changes to servers

When a server needs to be (re-)configured, login to control.ungleich.ch with ssh agent forwarding enabled. The username is the same as the customer you want to apply configurations for. If you want for instance to configure the ungleich infrastructure, proceed as follows:

<pre>

# Login to configuration server

ssh -A ungleich@control.ungleich.ch

# Ensure cdist configuration is up-to-date

cd ~/.cdist

git pull

# Configure

cdist config -vv <hostname>

</pre>
