Python client for the etcd API v3, supported under python 2.7, 3.4 and 3.5.

Warning: the API is mostly stable, but may change in the future

If you’re interested in using this library, please get involved.

Basic usage:

import etcd3

etcd = etcd3.client()

etcd.get('foo')
etcd.put('bar', 'doot')
etcd.delete('bar')

# locks
lock = etcd.lock('thing')
lock.acquire()
# do something
lock.release()

with etcd.lock('doot-machine') as lock:
    # do something

# transactions
etcd.transaction(
    compare=[
        etcd.transactions.value('/doot/testing') == 'doot',
        etcd.transactions.version('/doot/testing') > 0,
    ],
    success=[
        etcd.transactions.put('/doot/testing', 'success'),
    ],
    failure=[
        etcd.transactions.put('/doot/testing', 'failure'),
    ]
)

# watch key
watch_count = 0
events_iterator, cancel = etcd.watch("/doot/watch")
for event in events_iterator:
    print(event)
    watch_count += 1
    if watch_count > 10:
        cancel()

# watch prefix
watch_count = 0
events_iterator, cancel = etcd.watch_prefix("/doot/watch/prefix/")
for event in events_iterator:
    print(event)
    watch_count += 1
    if watch_count > 10:
        cancel()

# recieve watch events via callback function
def watch_callback(event):
    print(event)

watch_id = etcd.add_watch_callback("/anotherkey", watch_callback)

# cancel watch
etcd.cancel_watch(watch_id)

# recieve watch events for a prefix via callback function
def watch_callback(event):
    print(event)

watch_id = etcd.add_watch_prefix_callback("/doot/watch/prefix/", watch_callback)

# cancel watch
etcd.cancel_watch(watch_id)
