models. In order to do anything useful with a model, the juju lib must
connect to one of these endpoints. There are several ways to do this.
-For api docs, see :class:`juju.model.Model`.
+For api docs, see py:class:`juju.model.Model`.
Connecting to the Current Model
.. code:: python
- from juju.model import Model
-
model = Model()
- await model.connect_current()
+ await model.connect()
Connecting to a Named Model
.. code:: python
- # $ juju switch
- # juju-2.0.1:admin/libjuju
-
- from juju.model import Model
-
model = Model()
- await model.connect_model('juju-2.0.1:admin/libjuju')
+ await model.connect('juju-2.0.1:admin/libjuju')
-Connecting with Username/Password Authentication
-------------------------------------------------
-The most flexible, but also most verbose, way to connect is using the API
-endpoint url and credentials directly. This method does NOT require the Juju
-CLI client to be installed.
+Connecting with Authentication
+------------------------------
+You can control what user you are connecting with by specifying either a
+username/password pair, or a macaroon or bakery client that can provide
+a macaroon.
-.. code:: python
- from juju.model import Model
+.. code:: python
model = Model()
+ await model.connect(username='admin',
+ password='f53f08cfc32a2e257fe5393271d89d62')
+
+ # or with a macaroon
+ await model.connect(macaroons=[
+ {
+ "Name": "macaroon-218d87053ad19626bcd5a0eef0bc9ba8bd4fbd80a968f52a5fd430b2aa8660df",
+ "Value": "W3siY2F2ZWF0cyI6 ... jBkZiJ9XQ==",
+ "Domain": "10.130.48.27",
+ "Path": "/auth",
+ "Secure": false,
+ "HostOnly": true,
+ "Expires": "2018-03-07T22:07:23Z",
+ },
+ ])
- controller_endpoint = '10.0.4.171:17070'
- model_uuid = 'e8399ac7-078c-4817-8e5e-32316d55b083'
- username = 'admin'
- password = 'f53f08cfc32a2e257fe5393271d89d62'
-
- # Left out for brevity, but if you have a cert string you should pass it in.
- # You can copy the cert from the output of The `juju show-controller`
- # command.
- cacert = None
-
- await model.connect(
- controller_endpoint,
- model_uuid,
- username,
- password,
- cacert,
- )
-
+ # or with a bakery client
+ from macaroonbakery.httpbakery import Client
+ from http.cookiejar import FileCookieJar
-Connecting with Macaroon Authentication
----------------------------------------
-To connect to a shared model, or a model an a shared controller, you'll need
-to use macaroon authentication. The simplest example is shown below, and uses
-already-discharged macaroons from the local filesystem. This will work if you
-have the Juju CLI installed.
+ bakery_client=Client()
+ bakery_client.cookies = FileCookieJar('cookies.txt')
+ model = Model()
+ await model.connect(bakery_client=bakery_client)
+
-.. note::
- The library does not yet contain support for fetching and discharging
- macaroons. Until it does, if you want to use macaroon auth, you'll need
- to supply already-discharged macaroons yourself.
+Connecting with an Explicit Endpoint
+------------------------------------
+The most flexible, but also most verbose, way to connect is using the API
+endpoint url, model UUID, and credentials directly. This method does NOT
+require the Juju CLI client to be installed.
.. code:: python
- from juju.client.connection import get_macaroons()
from juju.model import Model
model = Model()
-
- controller_endpoint = '10.0.4.171:17070'
- model_uuid = 'e8399ac7-078c-4817-8e5e-32316d55b083'
- username = None
- password = None
- cacert = None
- macaroons = get_macaroons()
-
await model.connect(
- controller_endpoint,
- model_uuid,
- username,
- password,
- cacert,
- macaroons,
+ endpoint='10.0.4.171:17070',
+ uuid='e8399ac7-078c-4817-8e5e-32316d55b083',
+ username='admin',
+ password='f53f08cfc32a2e257fe5393271d89d62',
+ cacert=None, # Left out for brevity, but if you have a cert string you
+ # should pass it in. You can get the cert from the output
+ # of The `juju show-controller` command.

Creating and Destroying a Model
-------------------------------
Example of creating a new model and then destroying it. See
-:meth:`juju.controller.Controller.add_model` and
-:meth:`juju.controller.Controller.destroy_model` for more info.
+py:method:`juju.controller.Controller.add_model` and
+py:method:`juju.controller.Controller.destroy_model` for more info.
.. code:: python
Adding Machines and Containers
------------------------------
To add a machine or container, connect to a model and then call its
-:meth:`~juju.model.Model.add_machine` method. A
-:class:`~juju.machine.Machine` instance is returned. The machine id
+py:method:`~juju.model.Model.add_machine` method. A
+py:class:`~juju.machine.Machine` instance is returned. The machine id
can be used to deploy a charm to a specific machine or container.
.. code:: python
------------------------------
To watch for and respond to changes in a model, register an observer with the
model. The easiest way to do this is by creating a
-:class:`juju.model.ModelObserver` subclass.
+py:class:`juju.model.ModelObserver` subclass.
.. code:: python
# specific handler method is not defined.
-Any :class:`juju.model.ModelEntity` object can be observed directly by
+Any py:class:`juju.model.ModelEntity` object can be observed directly by
registering callbacks on the object itself.
