Brokers hand off nodes to configuration management systems like Puppet Enterprise. Brokers consist of two parts: a broker type and information specific to the broker type.
Razor ships with three default broker types:
puppet-pe– Hands off node management to Puppet Enterprise. This broker specifies the address of the Puppet server, the Puppet Enterprise version, and for Windows, the location of the Windows agent installer.
puppet– Hands off management to open source Puppet. This broker specifies the address of the Puppet server, the node certname, and the environment.
noop– Doesn’t hand off management. A no-op broker can be useful for getting started quickly or doing a basic installation without configuration management.
You can create brokers using the
create-broker command. You can also update configuration details for the broker and delete brokers.
Writing new broker types is only necessary to use Razor with other configuration management systems.
There are two directories that store brokers:
/opt/puppetlabs/server/apps/razor-server/share/razor-server/brokersstores default brokers shipped with the product.
/etc/puppetlabs/razor-server/brokersstores custom brokers that you create.
Tip: We recommend not modifying the directory or brokers at
/opt..., but you can copy brokers from there to the custom broker directory and modify them as needed.
To create a PE broker that enrolls nodes with the Puppet master at
razor create-broker --name=my_puppet --broker-type=puppet-pe \ --configuration server=puppet.example.org \ --configuration version=2015.3
To create a broker called
From the command line, create a
sample.broker directory anywhere on the
broker_path is specified in the
broker_path class parameter of the
pe_razor module. By default, the broker directory for custom brokers is
install.ps1.erb(Windows Powershell) template in the
The broker install script is generated from the
install.erb (nix) or
install.ps1.erb (Windows) template of your broker. The template returns a valid shell script because tasks generally perform the handoff to the broker by running a command like
curl -s <%= broker_install_url %> | /bin/bash. The
GET request to
broker_install_url (nix) or
broker_install_url('install.ps1') (Windows) returns the broker’s install script after interpolating the template.
In the install template, you have access to two objects:
node object gives you access to node facts (
node.facts["example"]), tags (
node.tags), and metadata (
broker object gives you access to the configuration settings. For
example, if your
configuration.yaml specifies that a setting
must be provided when creating a broker from this broker type, you can
access the value of
version for the current broker as
configuration.yaml file indicates what parameters can be supplied for any given broker type. For each parameter, you can supply these attributes:
description- Human-readable description of the parameter.
trueto indicate that the parameter must be supplied. Parameters that aren’t required are optional.
default- Value for the parameter if one isn’t supplied.
As an example, here’s the configuration.yaml for the PE broker type:
server: description: "The puppet master to load configurations and installation packages from." version: description: "Override the PE version to install; defaults to `current`." windows_agent_download_url: description: "The download URL for a Windows PE agent installer; defaults to a URL derived from the `version` config."
