udns is an authoritative, caching DNS server for development and small
deployments written in `Python`_ using the `circuits`_ Application Framework
and the `dnslib`_ DNS library. udns can be run standalone, via `Docker`_
or using the `Docker Compose`_ tool. udns is designed to be small,
lightweight, fast and flexible. udns fully supports forwarding, caching
as well as honoring TTL(s). udns will also read your ``/etc/hosts`` file
at startup and use this to populate an internal hosts cache so that entries
in your local ``/etc/hosts`` file are fully resolvable with tools such as
``host``, ``dig`` and resolver client libraries.

    $ cd udns
    $ docker-compose up -d                  # Server
    $ docker-compose run --rm udns udnsc    # Client

Using `Docker`_::
    
    $ docker run -d -p 53:53/udp prologic/udns

From PyPi (*coming soon*)::

    $ udnsd     # Server
    $ udnsc     # Client


Running as a Daemon::
    
    $ sudo udnsd -d --logfile=$(pwd)/udnsd.log --pidfile=$(pwd)/udnsd.pid


Managing Zones and Records
--------------------------

udns is a full authoritative, caching DNS server and ships with a client to
help manage zones and records. Here are some quick examples:

Create new Zone::
    
    $ udnsc create abc.com.

Create new Zone from a file::
    
    $ udnsc create abc.com. abc.com

or:::
    
    $ udnsc create abc.com. - < abc.com

List Zones::
    
    $ udnsc list

Show Zone Records::
    
    $ udnsc show abc.com.

Export a Zone:::
    
    $ udnsc export abc.com.

.. note:: This exports the Zone to stdout which you can pipe into an output
          file for storage using your shell.
          e.g: ``udnsc export abc.com. > abc.com``

Add Zone Records::
    
    $ udnsc add abc.com. www 127.0.0.1

Delete a Zone Record::
    
    $ udnsc delete abc.com. www

Delete a Zone::
    
    $ udnsc delete abc.com.

.. note:: You __must__ specify zones as fully qualified domain names with a
          trailing period. e.g: ``abc.com.``
