Python client for the Serf orchestration tool
Project description
trio-serf is an async Python interface to Serf, the decentralised solution for service discovery and orchestration.
It uses trio <https://github.com/python-trio/trio> as its underlying async framework. Previous versions used the anyio <https://github.com/agronholm/anyio> wrapper, thus worked with asyncio, trio, and curio, but this has been discontinued because of issues with error handling.
Installation
trio-serf requires a running Serf agent. See Serf’s agent documentation for instructions.
To install trio-serf, run the following command:
$ pip install trio-serfor alternatively (you really should be using pip though):
$ easy_install trio-serfor from source:
$ python setup.py installGetting Started
These examples require a running async loop. Trio <https://github.com/python-trio/trio> is recommended, though asyncio works too.
from trio_serf import serf_client
async with serf_client() as client:
await client.event('foo', 'bar')Stream usage:
from trio_serf import serf_client
async with serf_client() as client:
async with client.stream('*') as stream:
async for resp in stream:
print(resp)Development
You can run the tests using the following commands:
$ serf agent --tag foo=bar & # start serf agent
$ python3 -mpytest tests
