Puppet communication pattern:🔗

  1. Agent sends facts to master and requests a catalogue.
  2. Master compiles and returns the node's catalogue using the sources of information the master has access to.
  3. Agent applies the catalogue to the node by checking each resource the catalogue describes. If it finds resources not in the desired state, it makes the changes necessary to correct them. Or, in no-op mode, it assesses what changes would be needed to reconsole the cataloge.
  4. Agent reports back to master.

Masters and agents communicate by HTTPS using SSL certificates.
