In this section, the RSA private keys, generated when setting up the Chef server, will be copied to the workstation to allow communicate between the Chef server and workstation. This ensures that the Chef server only communicates with trusted machines. Move into the chef-repo directory: mkdir ~/chef-repo/.chefДЄuthentication between the Chef server and workstation and/or nodes is completed with public key encryption. pem files that are used for RSA key pair authentication with the Chef server. chef generate repo chef-repoД®nsure that your workstationвЂ™s /etc/hosts file maps its IP address to your Chef serverвЂ™s fully qualified domain name and workstation hostnames.
