Puppet Enterprise 2019.0

There are five key steps for provisioning nodes with Razor.

Figure 1. Razor identifies a node

When a new node appears, Razor discovers its characteristics by booting it with the Razor microkernel and using Facter to inventory its facts.

Figure 2. The node is tagged

The node is tagged based on its characteristics. Tags contain a match condition — a Boolean expression that has access to the node’s facts and determines whether the tag should be applied to the node or not.

Figure 3. The node tags match a Razor policy

Node tags are compared to tags in the policy table. The first policy with tags that match the node’s tags is applied to the node.
Figure 4. Policies pull together all the provisioning elements

The node is now installed. If you choose, you can hand off management of the node to Puppet Enterprise.
