How to configure servers with cdist


We are using cdist to manage our system configurations. This software has originally been developped by ungleich-folk, but now has a much broader community.

The ungleich cdist environment

Our environment is composed of 4 repositories:

Applying changes to servers

Initial setup:

  • Clone ungleich-intern/cdist-workdir
  • Install ''myrepos'' and - within cdist-workdir - run ''mr update''.
  • Set your ''CDIST_PATH'', using - for example - the ''cdist.cfg'' file in cdist-workdir.

Day-to-day workflow, within cdist-workdir:

  • Make sure you have the latest configuration/types with ''mr update''.
  • Configure the target host with ''cdist config -vv <hostname>''.

Using the control node

You can use the control node to run cdist when you're using an unreliable connection (in a train, far away in Korea, etc.). Note that you will have to forward your SSH agent with the ''-A'' ssh flag.

# Login to configuration server
ssh -A

# Ensure cdist configuration is up-to-date
cd cdist-workdir
mr update

# Configure
cdist config -vv <hostname>
