a service framework

Project description

https://travis-ci.org/deliveryhero/lymph.svg?branch=master

Lymph

lymph is an opinionated framework for Python services. Its features are

  • Discovery: pluggable service discovery (e.g. backed by ZooKeeper)

  • RPC: request-reply messaging (via ZeroMQ + MessagePack)

  • Events: pluggable and reliable pub-sub messaging (e.g. backed by RabbitMQ)

  • Process Management

There’s documentation on readthedocs.org.

Installation (as a dependency)

# py-monotime requires python headers, and gevent and cython require build-essential
$ sudo apt-get install build-essential python-dev
$ pip install https://github.com/deliveryhero/lymph.git#egg=lymph

Development (of lymph itself)

$ git clone https://github.com/deliveryhero/lymph.git
$ cd lymph
$ pip install -r requirements/base2.txt -r requirements/dev.txt
$ pip install -e .

Run tests with tox, build documentation with fab docs.

Running services

To run the example services, you can use the example node config in conf/sample-node.yml. You’ll also need a local installation of ZooKeeper (with the configuration provided in the Getting Started Guide) and RabbitMQ:

$ export PYTHONPATH=examples
$ cp conf/sample-node.yml .lymph.yml
$ lymph node

You can then discover running services:

$ lymph discover

and send requests to them from the commandline:

$ lymph request echo.upper '{"text": "transform me"}'

To see the log output of a running service, try:

$ lymph tail echo -l DEBUG
