Example Skillet

In this example, we will create a skillet that allows the user to customize a single variable. Of course, finding the correct XML and XPath information is not at all obvious. However, there are many tools available to assist with this such as SLI and Skillet Builder.

XML Fragment

First, we’ll extract the parts of the configuration that comprise this ‘unit’ of configuration changes (a skillet). For example, this portion of the configuration describes the log-settings we would like to modify:

     <entry name="dhcp-log-match">
        <filter>(eventid eq lease-start)</filter>
    <entry name="mgmt-interface">
            <entry name="mgmt-intf">
                <server>{{ MGMT_IP }}</server>

Notice here we have defined one variable: MGMT_IP. This will allow the user to insert their own management ip when deploying.

Skillet file

The skillet file itself is a YAML file with a suffix of .skillet.yaml. You may also prefix the filename, for example: example.skillet.yaml. See YAML Syntax for complete details.

name: example_log_setting
label: Log Setting Example
description: Example log setting to configure syslog
type: panos

  service_type: userid

  - name: MGMT_IP
    description: NGFW management IP address
    type_hint: ip_address

  - name: log_settings
    cmd: set
    xpath: /config/shared/log-settings
    file: log_settings.xml

In this file, we give some basic information about what this skillet will do, what configuration bits will be applied, and what variables the user can customize. Notice in the ‘variables’ section, we specify a variable entry with a ‘name’ that matches the variable defined in the XML fragment. The ‘snippets’ section will inform Panhandler where in the configuration this fragment should be inserted (xpath) and where to find the fragment (file).
