# Docker Quickstart

```sh
docker pull privex/neighgen

docker run --rm -it privex/neighgen -h

docker run --rm -it privex/neighgen asinfo -x -F 210083
docker run --rm -it privex/neighgen asinfo -x 210083
docker run --rm -it privex/neighgen asinfo-raw 210083
docker run --rm -it privex/neighgen neigh 210083
docker run --rm -it privex/neighgen neigh -o ios 210083
```

If you'd like to be able to query PeeringDB locally via a database, you can use the Docker Compose
environment which comes prepared in the Git project.

Clone the repo:

```sh
git clone https://github.com/Privex/neighgen.git
```

Copy `dk-config.yaml` for docker-compose to use:

```sh
cp example.dk-config.yaml dk-config.yaml
```

Then simply run `docker-compose up -d` , which will build both the neighgen and postgres containers,
then start them up in the background.

```sh
docker-compose up -d
```

You can monitor neighgen's import process via docker's logging:

```sh
docker-compose logs -f ngen
```

Once it's finished syncing, you should be able to enter the postgres container, and
make whatever queries you want:

```sh
docker-compose exec postgres psql -U peeringdb peeringdb
```

Please be aware that the PeeringDB database generation, is not part of this repo.

The PeeringDB local DB sync functionality is provided by the `peeringdb` package: https://github.com/peeringdb/peeringdb-py

# Installing

## From PyPi

We recommend installing the package on the newest version of Python that your OS has available.

Most modern LTS releases at the time, such as Ubuntu 20.04 and Debian 10 - have at LEAST
Python 3.8 available, while Ubuntu 20.04 has 3.9 available.

For example, if the newest version of Python on your system is 3.8, then you'd install
it on Python 3.8 like so:

```sh
python3.8 -m pip install -U privex-neighgen
```

If for some reason, your Python distribution doesn't support the `python3.x -m pip` method of
calling Pip, then you can use the classic `pip3` command instead:

```sh
pip3 install -U privex-neighgen
```

## From Github

```sh
git clone https://github.com/Privex/neighgen.git
cd neighgen
# Option 1. - Install NeighGen onto your system from the repo
pip3 install -U .

# Option 2. - Create a Pipenv virtualenv, and use the software
# straight from the project folder:
pip3 install -U pipenv
pipenv install
pipenv install --dev
pipenv shell

python3 -m neighgen -h
python3 -m neighgen asinfo 210083

```

# Configuration

The software is primarily configured through a YML config file.

You can generate a base example config at `~/.ngen.yml` using the following command:

```sh
neighgen gen_config -o ~/.ngen.yml yml
```

The application will search the following locations for the config, in order,
until it finds one that exists. It will only load the first config it finds:

```py
from os import getcwd
from pathlib import Path
PWD = Path(getcwd()).expanduser().resolve()
_CONFIG_FILES = [
    'config.yaml', 'config.yml', 'ngen.yaml', 'ngen.yml',
    PWD / 'config.yaml', PWD / 'config.yml', PWD / 'ngen.yaml', PWD / 'ngen.yml',
    '~/.neighgen/config.yaml', '~/.neighgen/config.yml'
    '~/.ngen/config.yaml', '~/.ngen/config.yml'
    '~/.ngen.yaml', '~/.ngen.yml'
    '~/.peeringdb/config.yaml', '~/.peeringdb/config.yml'
]
```

The first files in that list, are scanned within the base folder of the project, i.e. it will look
for `config.yaml` / `config.yml` / `ngen.yaml` / `ngen.yml` in the root of the project,
where `LICENSE.txt` , `Dockerfile` , `README.md` and other files are located.

The second line of files, search within your current working directory, which can be helpful
if you've installed the application via pip, so that it will use `config.yml` / `ngen.yaml`
in whatever directory you're currently cd'd into.

You can also generate an example ENV file, however, you should only use an ENV file / environment args
if you have a specific reason that the YML file isn't suitable on it's own, e.g. for configuring the
app from within some form of management system that uses ENV files (e.g. systemd).

```sh
# This will just output to your terminal. You can use either '-o', or you can
# pipe the contents to where-ever you want the ENV file to be.
neighgen gen_config env
```

The last type of config which `neighgen` can generate - is a slightly modified version of the standard
YML config, but pre-configured for use with Docker (esp. with the docker-compose setup).

To generate the Docker-focused YML config:

```sh
neighgen gen_config -o dk-config.yaml docker
```

# Examples

## asinfo

Display PeeringDB information for AS210083 (Privex) as pretty printed tables:

    python3 -m neighgen asinfo 210083

Display PeeringDB information for AS210083 (Privex) as pretty printed tables,
and include internet exchange information:

    python3 -m neighgen asinfo -x 210083

Display PeeringDB information for AS210083 (Privex) as pretty printed tables,
and include both internet exchange information, and facility information:

    python3 -m neighgen asinfo -x -F as210083

## asinfo-raw

Display PeeringDB info for AS210083 in programmatic form - which by default is JSON:

    python3 -m neighgen asinfo-raw 210083

Display PeeringDB info for AS210083 in programmatic form, including both IXP and facility info:
    
    python3 -m neighgen asinfo-raw -x -F 210083

Display ONLY IXP information from PeeringDB for AS210083 in programmatic form:

    python3 -m neighgen asinfo-raw -OX 210083

Display ONLY Facility information from PeeringDB for AS210083 in programmatic form:

    python3 -m neighgen asinfo-raw -OF 210083

Display ONLY IXP information from PeeringDB for AS210083 in programmatic form - but as YAML
instead of JSON:

    python3 -m neighgen asinfo-raw -OX 210083 yml

Display PeeringDB info for AS210083 in programmatic form, including both IXP and facility info,
but as XML instead of JSON:

    python3 -m neighgen asinfo-raw -x -F 210083 xml

## neigh

Display neighbour configuration for peering with AS210083 at all of their IXPs,
using the default OS config format 'nxos' (Cisco NX-OS):

    python3 -m neighgen neigh 210083

Display neighbour configuration for peering with AS210083 at only exchanges with 'ams-ix'
in their name, using the default OS config format 'nxos' (Cisco NX-OS):

    python3 -m neighgen neigh 210083 ams-ix

Display neighbour configuration for peering with AS210083 at only exchanges with 'ams-ix'
in their name, this time we manually specify that we want the config to be formatted
for use with 'ios' (Cisco IOS).

    python3 -m neighgen neigh -o ios 210083 ams-ix

Same as previous, but we set the peer-policy for v4 and v6 to blank, which disables
it from adding peer-policy neighbour commands:

    python3 -m neighgen neigh -p4 '' -p6 '' -o ios 210083 ams-ix

The network AS13335 peers at several different AMS-IX regions, so to limit the neighbours to
use only the IXP called "AMS-IX", and not "AMS-IX Hong Kong" or "AMS-IX Caribbean",
we use "-X" to enable exact IXP matching (the matching isn't case sensitive though).
This ensure it only uses IXP peers on the exchange named "AMS-IX" and not their
other regions.

    python3 -m neighgen neigh -X 13335 ams-ix
