Installing agents using Puppet Discovery is one of the easiest ways to install Puppet agents throughout your infrastructure. You're currently able to provide the following parameters and apply the tasks to a list of hosts:

• master: Which Puppet Master to use. This is the only non-optional parameter.
• cacert_content: Expected CA certificate the Master should return.
• certname: Certname of agent.
• environment: Environment the node should run in.
• dns_alt_names: DNS alternate names baked into the agent certificate.
• custom_attributes: Any custom CSR attributes.
• extension_request: Any specific extension requests (such as pp_role) to add to the certificate.
