Now that we can deal with a large number of nodes in our installation, we need a way to organize the classes we apply to each node.
There are a few solutions to the problem of attaching classes to nodes. In this chapter, we will examine the following node organization methods:
- An external node classifier (ENC)
- LDAP backend
- Hiera
For the remainder of this chapter, we will assume that your Puppet infrastructure is configured with a single Puppet master running puppetserver. We will name this server puppet and give it the IP address 192.168.1.1. Any Puppet master configuration will be sufficient for this chapter; the configuration from the previous chapter was used in the examples of this chapter.
