distconfig
Library to manage distributed configuration using either ZooKeeper <https://zookeeper.apache.org/>
_ or
Etcd <https://github.com/coreos/etcd>
_ or Consul <http://www.consul.io/>
_.
Rational
When you have to manage configuration of a given services that are distributed across nodes, you may want
to consider using either one of the distributed configuration managers e.g. zookeeper, etcd, consul ..., this
library goal is to give developers an easy access to configuration stored in the previous backends.
Installation:
To use ZooKeeper as backend you should install distconfig
using ::
$ pip install distconfig[zookeeper]
with etcd::
$ pip install distconfig[etcd]
with consul::
$ pip install distconfig[consul]
Usage:
Example using zookeeper as a backend ::
from kazoo import client
from distconfig import Proxy
client = client.KazooClient()
# The user must call ``KazooClient.start()`` before using this particular
# backend
client.start()
proxy = Proxy.configure(
'distconfig.backends.zookeeper.ZooKeeperBackend',
client=client,
)
# config is a read only mapping-like object.
config = proxy.get_config('/distconfig/service_name/config')
print config['key']
# Getting nested values works by supplying key seperated by '/' char.
print config['key/inner']
# You can assert key value type by using typed get function e.g.
# get_int, get_float, get_unicode, get_bytes ... .
print config.get_int('key/inner/int_key')
# Getting a inner config.
print config.get_config('key/inner/dict_key')
Development:
Start by installing dependencies ::
$ pip install -r requirements/dev.txt requirements/base.txt
To run unit test use tox ::
$ tox
To run integration test, we recommend you to install docker <https://www.docker.com/>
_ and then run ::
$ ./run-tests.sh
The above script will setup docker container for each of the backend
and run the integration tests on them.
