How often do you wonder where to store the project settings? When your project is small

it is not a big problem. But if your big project consists of dozens of microservices

then there is a problem of centralized configuration management. The Сonsul have a key/value

storage that is ideal for this.

With **consul-options** you can define and use options in your code by a simple and elegant way.

Just take a look at the example:

.. code-block:: python

    class DB(ConsulKV):

        pass

    class Users(DB):

        host = '127.0.0.1'

        port = 5432

        user = 'postgres'

        password = 'postgres'

        dbname = 'users'

    class Orders(DB):

        host = '127.0.0.1'

        port = 5432

        user = 'postgres'

        password = 'postgres'

        dbname = 'orders'

Now you can access option values in a clear way:

.. code-block:: python

    from consul_options import options

    print options.db.users.host

    print options.db.orders.dbname

**consul-options** automagically creates folders and keys with default values defined above

in Consul and later read them from there. So if anyone will change the value of *db/orders/host* key

to something different in Consul then you will get that value.

How project options stored in Consul

------------------------------------

When you declare a new class based on **ConsulKV** default bahavior is

creation a *folder* in Consul key/value storage with name of your class in lowercase.

Each class attribute you define will have mapping to key *folder/key*.

If you don't agree with generated folder name you are free to choose any other

with reserved class attribute **__key__** as shown below:

.. code-block:: python

    class WorkerOptions(ConsulKV):

        __key__ = 'worker'

        host = '127.0.0.1'

        port = 80

After that you can access to the option with "worker" in path:

.. code-block:: python

    from consul_options import options

    print options.worker.host

    print options.worker.port

To create hierarchical key structure you can take advantage of usual class hierarchy:

.. code-block:: python

    from consul_options import ConsulKV, options

    class WorkerOptions(ConsulKV):

        __key__ = 'worker'

        host = '127.0.0.1'

        port = 80

    class DB(WorkerOptions):

        host = '127.0.0.1'

        port = 5432

        user = 'postgres'

        password = 'postgres'

    print options.worker.db.host  # 'host'

    print options.worker.db.port  # 5432

It is also possible to create keys at root level with class attribute **__root__**:

.. code-block:: python

    class RootOptions(ConsulKV):

        __root__ = True

        host = '127.0.0.1'

        port = 80

    print options.host

    print options.port
