Manipulate DNS records on various DNS providers in a standardized/agnostic way.

## Introduction
Lexicon provides a way to manipulate DNS records on multiple DNS providers in a standardized way.
Lexicon has a CLI but it can also be used as a python library.

Lexicon was designed to be used in automation, specifically letsencrypt.

## Providers
Only DNS providers who have an API can be supported by `lexicon`.

The current supported providers are:

- cloudflare ([docs](https://api.cloudflare.com/#endpoints))
- pointhq ([docs](https://pointhq.com/api/docs))
- dnsimple ([docs](https://developer.dnsimple.com/))

The next planned providers are:

- pointhq
- namecheap
- route 53

## Setup
To use lexicon as a CLI application, do the following:

pip install dns-lexicon

You can also install the latest version from the repository directly.

pip install git+https://github.com/AnalogJ/lexicon.git

## Usage

$ lexicon -h
usage: cli.py [-h] [--name NAME] [--content CONTENT] [--ttl TTL]
[--priority PRIORITY] [--identifier IDENTIFIER]
[--auth-username AUTH_USERNAME] [--auth-password AUTH_PASSWORD]
[--auth-token AUTH_TOKEN] [--auth-otp-token AUTH_OTP_TOKEN]
{base,cloudflare,__init__} {create,list,update,delete} domain
{A,CNAME,MX,SOA,TXT}

Create, Update, Delete, List DNS entries

positional arguments:
{cloudflare}
specify the DNS provider to use
{create,list,update,delete}
specify the action to take
domain specify the domain, supports subdomains as well
{A,CNAME,MX,SOA,TXT} specify the entry type

optional arguments:
-h, --help show this help message and exit
--name NAME specify the record name
--content CONTENT specify the record content
--ttl TTL specify the record time-to-live
--priority PRIORITY specify the record priority
--identifier IDENTIFIER
specify the record for update or delete actions
--auth-username AUTH_USERNAME
specify username used to authenticate to DNS provider
--auth-password AUTH_PASSWORD
specify password used to authenticate to DNS provider
--auth-token AUTH_TOKEN
specify token used authenticate to DNS provider
--auth-otp-token AUTH_OTP_TOKEN
specify OTP/2FA token used authenticate to DNS
provider

Using the lexicon CLI is pretty simple:

# setup provider environmental variables:
LEXICON_CLOUDFLARE_USERNAME="[e-mail]"
LEXICON_CLOUDFLARE_TOKEN="cloudflare-api-token"

# list all TXT records on cloudflare
lexicon cloudflare list example.com TXT

# create a new TXT record on cloudflare
lexicon cloudflare create www.example.com TXT --name "_acme-challenge.www.example.com." --content "challenge token"

# delete a TXT record on cloudflare
lexicon cloudflare delete www.example.com TXT --name "_acme-challenge.www.example.com." --content "challenge token"
lexicon cloudflare delete www.example.com TXT --identifier "cloudflare record id"



### Letsencrypt Instructions
Lexicon has an example [letsencrypt.sh hook file](examples/letsencrypt.cloudflare.sh) that you can use for any supported provider.
All you need to do is change the PROVIDER parameter.

letsencrypt.sh --cron --hook letsencrypt.cloudflare.sh --challenge dns-01


## TroubleShooting & Useful Tools
There is an included example Dockerfile that can be used to automatically generate certificates for your website.

## ToDo list

- [x] Create and Register a lexicon pip package.
- [ ] Write documentation on supported environmental variables.
- [ ] Wire up automated release packaging on PRs.
