{
    "type": "chef-solo",
    "cookbook_paths": ["chef/cookbooks/vendor"],
    "roles_path": "chef/roles",
    "json": {
          "jenkins": {
            "master": {
              "port": 8080
            },
            "executor": {
              "timeout": 300
            }
          },
          "jenkins-cookbook": {
            "admin_user": "uname",
            "admin_pass": "pwd"
          }
    },
    "run_list":["role[jenkins]"]
}

• as per the packer documentation we can pass the node attributes in the form of json
