Python library for Juju
Project description
Source code: https://github.com/juju/python-libjuju
Bug reports: https://github.com/juju/python-libjuju/issues
Documentation: https://pythonlibjuju.readthedocs.io/en/latest/
Requirements
Python 3.5+
Juju 2.0+
Design Notes
Asynchronous - uses asyncio and async/await features of python 3.5
Websocket-level bindings are programmatically generated (indirectly) from the Juju golang code, ensuring full api coverage
Provides an OO layer which encapsulates much of the websocket api and provides familiar nouns and verbs (e.g. Model.deploy(), Application.add_unit(), etc.)
Installation
pip3 install jujuQuickstart
Here’s a simple example that shows basic usage of the library. The example connects to the currently active Juju model, deploys a single unit of the ubuntu charm, then exits:
#!/usr/bin/python3
import logging
import sys
from juju import loop
from juju.model import Model
async def deploy():
# Create a Model instance. We need to connect our Model to a Juju api
# server before we can use it.
model = Model()
# Connect to the currently active Juju model
await model.connect_current()
try:
# Deploy a single unit of the ubuntu charm, using the latest revision
# from the stable channel of the Charm Store.
ubuntu_app = await model.deploy(
'ubuntu',
application_name='ubuntu',
series='xenial',
channel='stable',
)
if '--wait' in sys.argv:
# optionally block until the application is ready
await model.block_until(lambda: ubuntu_app.status == 'active')
finally:
# Disconnect from the api server and cleanup.
await model.disconnect()
def main():
logging.basicConfig(level=logging.INFO)
# If you want to see everything sent over the wire, set this to DEBUG.
ws_logger = logging.getLogger('websockets.protocol')
ws_logger.setLevel(logging.INFO)
# Run the deploy coroutine in an asyncio event loop, using a helper
# that abstracts loop creation and teardown.
loop.run(deploy())
if __name__ == '__main__':
main()More examples can be found in the docs, as well as in the examples/ directory of the source tree which can be run using tox. For example, to run examples/connect_current_model.py, use:
tox -e example -- examples/connect_current_model.pyVersioning
Pylibjuju releases now track the Juju release cadence. New generated schemas will be updated per Juju releases.
