Wrapper around python-etcd3 to support DNS SRV discovery of endpoints. Supports Python 2.7 and 3.5.

Installation

Install packages:

• python3
• python3-pip
• python3-setuptools
• python3-wheel
• python3-dnspython

For etcd3 dependency:

• python3-dev
• gcc
• g++

Install the package itself:

git checkout 1.0.2
python3 setup.py build
sudo python3 setup.py install

or

pip3 install --process-dependency-links git+https://github.com/answear/python-etcd3autodiscover.git@1.0.2

Usage

Assume you have SRV record _etcd._tcp.svc.internal defined as:

Server:		127.0.0.1
Address:	127.0.0.1#53

_etcd._tcp.svc.internal	service = 0 0 2379 etcd0.internal.
_etcd._tcp.svc.internal	service = 0 0 2379 etcd1.internal.
_etcd._tcp.svc.internal	service = 0 0 2379 etcd2.internal.

from etcd3autodiscover import Etcd3Autodiscover

etcd = Etcd3Autodiscover(host='svc.internal', port=2379, timeout=5)
client = etcd.connect()

if client is None:
	print(etcd.errstr())
else:
	client.put('/key', 'val')
	print(client.get('/key'))
