  • Puppet agent nodes and Puppet masters communicate by HTTPS with client verification.

  • The Puppet master provides an HTTP interface, with various endpoints available. 

  • When requesting or submitting anything to the master, the agent makes an HTTPS request to one of those endpoints.

  • Client-verified HTTPS means each master or agent must have an identifying SSL certificate. 

  • They each examine their counterpart’s certificate to decide whether to allow an exchange of information.

  • Puppet includes a built-in certificate authority for managing certificates.

  • Agents can automatically request certificates through the master’s HTTP API

  • You can use the puppet cert command to inspect requests and sign new certificates. 

  • And agents can then download the signed certificates.
