Create roles and assign cookbooks to them.

roles/ntp.json

{
   "name": "ntp",
   "description": "NTP server role.",
   "json_class": "Chef::Role",
   "default_attributes": {
     "chef_client": {
       "interval": 60,
       "splay": 1
     }
   },
   "override_attributes": {
   },
   "chef_type": "role",
   "run_list": ["recipe[chef-client::default]",

                "recipe[ntpd::default]"
   ],

   }
}

1. Upload the role to the Chef Server : knife role from file roles/web.json
2. Check that the role is on the server : knife role list - knife role show ntp
3. Find node name from knife node list - knife node run_list set puppet-minion1 "role[ntp]"
4. Confirm that the role is applied to the Node : knife node show puppet-minion1 --run-list
5. Run chef-client on the node.
6. knife ssh 10.255.255.8 'role:web' 'sudo chef-client' --ssh-user sysadmin --ssh-password 'PASSWORD_HERE' --sudo --use-sudo-password --node-name puppet-minion1
