Bare-Metal Provisioning with Razor
A newer version is available; see the version menu above for details.
Razor is an advanced provisioning application that can deploy bare metal systems. Razor makes it easy to provision a node with no previously installed operating system and bring it under the management of Puppet Enterprise (PE).
Razor’s policy-based bare-metal provisioning lets you inventory and manage the lifecycle of your physical machines. With Razor, you can automatically discover bare-metal hardware, dynamically configure operating systems and/or hypervisors, and hand nodes off to PE for workload configuration.
Razor policies use discovered characteristics of the underlying hardware and user-provided data to make provisioning decisions.
Note: Be aware that Razor is designed to take over provisioning for your infrastructure, so if you’re planning on deploying it into an existing environment, you should read and understand the caveats first.
How Razor Works
The following steps provide a high-level view of the process for provisioning a node with Razor.
Razor identifies a new node
When a new node appears, Razor discovers its characteristics by booting it with the Razor microkernel and using Facter to inventory its facts.
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.
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.
Policies pull together all the provisioning elements
The node is provisioned with the designated OS and managed with PE
The node is now installed and managed by Puppet Enterprise.
