When you're first using Puppet with just a few nodes, declaring the nodes' functionality right in the manifest works fine.
But as you grow your Puppet deployment, you realize that this doesn't scale, especially in virtual environments where you don't even know about all your nodes when you're writing your manifest.
The Node Classifier helps you build a transparent, scalable, and intuitive process for managing your nodes based on their capabilities, not just their identities.
Come to this talk to learn about the Node Classifier's inheritance-based system for node classification. We'll cover:
- The basic concepts of the classification system.
- Setting up a classification hierarchy from scratch.
- Using the Node Classifier to support common tasks and workflows.
- Tips and tricks for developing your classifications, and for when things go awry.
