# Nautobot BGP Models Plugin

A plugin for [Nautobot](https://github.com/nautobot/nautobot) to extend the core models with BGP specific models. All types of BGP peerings can be model and managed, whether or not the device is present in Nautobot.

### 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](http://www.pyinvoke.org/) 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: nautobot-bgp-models)
* `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](https://docs.docker.com/compose/extends/#multiple-compose-files) for more information)

Using PyInvoke these configuration options can be overridden using [several methods](http://docs.pyinvoke.org/en/stable/concepts/configuration.html). Perhaps the simplest is simply setting an environment variable `INVOKE_NAUTOBOT_BGP_MODELS_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:

```shell
---
nautobot_bgp_models:
local: true
compose_files:
- "docker-compose.requirements.yml"
- "docker-compose.local.yml"
```

3. Run the following commands:

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

4. You can now run nautobot-server commands as you would from the [Nautobot documentation](https://nautobot.readthedocs.io/en/latest/) for example to start the development server:

```shell
nautobot-server runserver 0.0.0.0:8080 --insecure
```

Nautobot server can now be accessed at [http://localhost:8080](http://localhost:8080).

#### Docker Development Environment

This project is managed by [Python Poetry](https://python-poetry.org/) and has a few requirements to setup your development environment:

1. Install Poetry, see the [Poetry Documentation](https://python-poetry.org/docs/#installation) for your operating system.
2. Install Docker, see the [Docker documentation](https://docs.docker.com/get-docker/) 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:

```shell
poetry shell
poetry install
invoke start
```

Nautobot server can now be accessed at [http://localhost:8080](http://localhost:8080).

### CLI Helper Commands

The project is coming with a CLI helper based on [invoke](http://www.pyinvoke.org/) 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_NAUTOBOT_BGP_MODELS_PYTHON_VER` and `INVOKE_NAUTOBOT_BGP_MODELS_NAUTOBOT_VER` may be specified to override the default versions. Each command also has its own help `invoke <command> --help`

#### Docker dev environment

```no-highlight
build Build all docker images.
debug Start Nautobot and its dependencies in debug mode.
destroy Destroy all containers and volumes.
restart Restart Nautobot and its dependencies.
start Start Nautobot and its dependencies in detached mode.
stop Stop Nautobot and its dependencies.
```

#### Utility

```no-highlight
cli Launch a bash shell inside the running Nautobot container.
create-user Create a new user in django (default: admin), will prompt for password.
makemigrations Run Make Migration in Django.
nbshell Launch a nbshell session.
```

#### Testing

```no-highlight
bandit Run bandit to validate basic static code security analysis.
black Run black to check that Python files adhere to its style standards.
flake8 This will run flake8 for the specified name and Python version.
pydocstyle Run pydocstyle to validate docstring formatting adheres to NTC defined standards.
pylint Run pylint code analysis.
tests Run all tests for this plugin.
unittest Run Django unit tests for the plugin.
```

# Example use of BGP Models plugin - Cisco BGP Configuration

This document provides an example of generating a Cisco device's desired BGP configuration based on data stored in Nautobot using this plugin. A GraphQL query is used to retrieve the relevant data, which is then rendered through a Jinja2 template to produce the desired configuration.

## Querying for the data
In order to retrieve a BGP data, following GraphQL can be issued to a Nautobot.

Example **PeerEndpoint** inheritance details:

- A `PeerEndpoint` inherits `AutonomousSystem` and `extra_attributes` fields from:
- `PeerGroup`
- `PeerGroupTemplate`
- `BGPRoutingInstance`
- `PeerGroup`
- `PeerGroupTemplate`
- `BGPRoutingInstance`

- A `PeerEndpoint` inherits `description`, `enabled`, `export_policy`, `import_policy` fields from:

- A `PeerEndpoint` inherits `source_ip`, `source_interface` fields from:
- `PeerGroup`
- `PeerGroup`

As an example, a `PeerEndpoint` associated with a `PeerGroup` will automatically inherit above attributes of the `PeerGroup` that haven't been defined at the `PeerEndpoint` level. If an attribute is defined on both, the value defined on the `PeerEndpoint` will be used.
