Plugins

Plugins are the source of all logic used in building a config. They can perform one of several tasks:

1. Generating configuration inventory lists for clients
2. Generating configuration entry contents for clients
3. Probing client-side state (like hardware inventory, etc) – the generic client probing mechanism is described at Probes.
4. Automating administrative tasks (e.g. SSHbase which automates ssh key management)
5. Generating client per-entry installation decision-lists
