IP Fabric ChatOps

An IP Fabric ChatOps plugin for Nautobot.

This plugin uses the Nautobot ChatOps base framework. It provides the ability to query data from IP Fabric using a supported chat platform (currently Slack, Webex Teams, MS Teams, and Mattermost).

Version Matrix

Here is a compatibility matrix and the minimum versions required to run this plugin:

Usage

Add a slash command to your chat platform called /ipfabric. See the nautobot-chatops installation guide for instructions on adding a slash command to your chat channel.

The following commands are available:

• /ipfabric set-snapshot [snapshot]: Set snapshot as reference for commands.
• /ipfabric get-snapshot: Get snapshot as reference for commands.
• /ipfabric device-list: Get the device list.
• /ipfabric interfaces [device] [metric]: Get interface metrics for a device.
• /ipfabric pathlookup [src-ip] [dst-ip] [src-port] [dst-port] [protocol]: Path simulation diagram lookup between source and target IP address.
• /ipfabric pathlookup-icmp [src-ip] [dst-ip] [icmp-type]: ICMP path simulation diagram lookup between source and target IP address.
• /ipfabric routing [device] [protocol] [filter-opt]: Get routing information for a device.
• /ipfabric wireless [option] [ssid]: Get wireless information by client or ssid.
• /ipfabric find-host [filter-key] [filter-value]: Get host information using the inventory host table.
• /ipfabric table-diff [category] [table] [snapshot] [view]: Get the diff of the category/table between the current snapshot and snapshot. Output view can be either a summary with counters or detailed with tables.

IP Fabric uses a concept of snapshots which can include different devices and data. The plugin supports querying specific snapshots via the /ipfabric set-snapshot command. The snapshot is set per user and cached for all future commands. If a snapshot is not set, the commands will default to $last unless a specific snapshot id is required.

Installation

The extension is available as a Python package in PyPI and can be installed with pip

pip install nautobot-chatops-ipfabric

The plugin is compatible with Nautobot 1.0.0 and higher

To ensure the IP Fabric ChatOps plugin is automatically re-installed during future upgrades, create a file named local_requirements.txt (if not already existing) in the Nautobot root directory (alongside requirements.txt) and list the nautobot-chatops-ipfabric package:

# echo nautobot-chatops-ipfabric >> local_requirements.txt

Once installed, the plugin needs to be enabled in your nautobot_configuration.py

# In your nautobot_configuration.py
PLUGINS = ["nautobot_chatops", "nautobot_chatops_ipfabric"]

PLUGINS_CONFIG = {
  "nautobot_chatops": {
    # ADD SLACK/MS-TEAMS/WEBEX-TEAMS/MATTERMOST SETTINGS HERE
  }
  "nautobot_chatops_ipfabric": {
      "IPFABRIC_API_TOKEN": os.environ.get("IPFABRIC_API_TOKEN"),
      "IPFABRIC_HOST": os.environ.get("IPFABRIC_HOST"),
      "IPFABRIC_VERIFY": os.environ.get("IPFABRIC_VERIFY", True),
  },
}

The plugin behavior can be controlled with the following list of settings

• IPFABRIC_API_TOKEN: Token for accessing IP Fabric API
• IPFABRIC_HOST: URL of IP Fabric instance
• IPFABRIC_VERIFY: Default: True; False to ignore self-signed certificates

Development

The development environment supports a self-contained environment for developing nautobot chatops commands.

Build of the environment requires python3-invoke. For development purposes, install poetry and use it to manage the required packages.

poetry install        # first time use
poetry shell

You can start the deveopment containers locally with an invoke build and invoke start after copying creds.env locally.

cp development/creds.env.example development/creds.env
invoke build
invoke start

You should be able to access nautobot at http://0.0.0.0:8080

Contributing

Pull requests are welcomed and automatically built and tested against multiple version of Python and multiple version of Nautobot through TravisCI.

The project is packaged with a light development environment based on docker-compose to help with the local development of the project and to run the tests within TravisCI.

The project is following Network to Code software development guideline and is leveraging:

• Black, Pylint, Bandit and pydocstyle for Python linting and formatting.
• Django unit test to ensure the plugin is working properly.

Development Environment

The development environment can be used in 2 ways. First, with a local poetry environment if you wish to develop outside of Docker. Second, inside of a docker container.

Invoke tasks

The PyInvoke library is used to provide some helper commands based on the environment. There are a few configuration parameters which can be passed to PyInvoke to override the default configuration:

• nautobot_ver: the version of Nautobot to use as a base for any built docker containers (default: develop-latest)
• project_name: the default docker compose project name (default: ipfabric)
• python_ver: the version of Python to use as a base for any built docker containers (default: 3.6)
• local: a boolean flag indicating if invoke tasks should be run on the host or inside the docker containers (default: False, commands will be run in docker containers)
• compose_dir: the full path to a directory containing the project compose files
• compose_files: a list of compose files applied in order (see Multiple Compose files for more information)

Using PyInvoke these configuration options can be overridden using several methods. Perhaps the simplest is simply setting an environment variable INVOKE_IPFABRIC_VARIABLE_NAME where VARIABLE_NAME is the variable you are trying to override. The only exception is compose_files, because it is a list it must be overridden in a yaml file. There is an example invoke.yml in this directory which can be used as a starting point.

Local Poetry Development Environment

1. Copy development/creds.example.env to development/creds.env (This file will be ignored by git and docker)
2. Uncomment the POSTGRES_HOST, REDIS_HOST, and NAUTOBOT_ROOT variables in development/creds.env
3. Create an invoke.yml with the following contents at the root of the repo:

---
ipfabric:
  local: true
  compose_files:
    - "docker-compose.requirements.yml"

4. Run the following commands:

poetry shell
poetry install
export $(cat development/dev.env | xargs)
export $(cat development/creds.env | xargs)

5. You can now run nautobot-server commands as you would from the Nautobot documentation for example to start the development server:

nautobot-server runserver 0.0.0.0:8080 --insecure

Nautobot server can now be accessed at http://localhost:8080.

Docker Development Environment

This project is managed by Python Poetry and has a few requirements to setup your development environment:

1. Install Poetry, see the Poetry Documentation for your operating system.
2. Install Docker, see the Docker documentation for your operating system.

Once you have Poetry and Docker installed you can run the following commands to install all other development dependencies in an isolated python virtual environment:

poetry shell
poetry install
invoke start

Nautobot server can now be accessed at http://localhost:8080.

CLI Helper Commands

The project is coming with a CLI helper based on invoke to help setup the development environment. The commands are listed below in 3 categories dev environment, utility and testing.

Each command can be executed with invoke <command>. Environment variables INVOKE_IPFABRIC_PYTHON_VER and INVOKE_IPFABRIC_NAUTOBOT_VER may be specified to override the default versions. Each command also has its own help invoke <command> --help
