nautobot-custom-jobs

This repo contains custom jobs for Nautobot.

Installation

Prerequisites

Follow the Nautobot documentation to install the jobs using either the Git repository method (Git Repositories – Jobs) or the local jobs directory method (Jobs).

Credentials

Jobs that connect to devices need to use credentials to do so and the nautobot-plugin-nornir plugin already provides a way to set a default username and password, as detailed here: https://github.com/nautobot/nautobot-plugin-nornir#installation

If customised credential logic is required it is possible to create a custom credential class and write your own credential logic.

The custom_credentials.py file provides an example of how to do this. In this example the credentials are defined by platform sepcific <PLATFORM>_USERNAME and <PLATFORM>_PASSWORD environment variables. The Nautobot device object is passed to the custom credentials function and the platform related to the device is used to look up the correct environment variables.

For example, if the platform name related to your device is defined as junos then the JUNOS_USERNAME and JUNOS_PASSWORD environment variables will be used.

If you decide to use the custom credentials you will need to change the nautobot-plugin-nornir plugin configuration in the nautobot_config.py file as follows:

PLUGINS_CONFIG = {
    "nautobot_plugin_nornir": {
        "nornir_settings": {
            "credentials": "custom_credentials.CustomNautobotORMCredentials",
        },
    },
}

Jobs

device_config.py

This file provides device configuation jobs. Currently there is a single job ‘Replace Device Configuration‘ which leverages the Nornir task napalm_configure to replace the configuration on the target device. Specifically the job uses the device intended configuration that is generated by the nautobot-plugin-golden-config plugin.

The job also provides a dry run option which can be used to test deployment of the intended configuration. The job results in the Nautobot UI will be populated with the device configuration diffs.
