AIOConsul¶
AIOConsul is a Python >= 3.5 library for requesting Consul API, build on top of asyncio and aiohttp.
Currently, this library aims a full compatibility with consul 0.7.
Sources are available at https://lab.errorist.xyz/aio/aioconsul.
Installation¶
pip install aioconsul
Tutorial¶
In this example I will show you how to join my cluster with another:
from aioconsul import Consul
client = Consul('my.node.ip')
# do I have a members?
members = await client.members.items()
assert len(members) == 1, "I am alone in my cluster"
# let's join another cluster
joined = await client.members.join('other.node.ip')
if joined:
members = await client.members.items()
assert len(members) > 1, "I'm not alone anymore"
And display the catalog:
datacenters = await client.catalog.datacenters()
for dc in datacenters:
print(dc)
services, _ = await client.catalog.services()
for service, tags in services.items():
print(service, tags)
nodes, _ = await client.catalog.nodes()
for node in nodes:
print(node.name, node.address)
Important¶
Version 0.7 breaks compatibility with previous versions:
- It is closer to what HTTP API returns
- It does not add consul property anymore
- Response with metadata are now a 2 items length tuple
