Provided Commands

The command line client is self-documenting. Use the --help or -h flag to access the usage options. You can find more command line client examples here

Python Library Usage

The full api is documented in the AutoScaling Offical Document site

Here's an example of listing metric types using Python library with keystone V3 authentication:

>>> from keystoneauth1 import session
>>> from keystoneauth1 import identity
>>> from asclient.v1 import client

>>> # Use Keystone API v3 for authentication as example
>>> auth = identity.v3.Password(auth_url=u'http://localhost:5000/v3',
...                             username=u'admin_user',
...                             user_domain_name=u'Default',
...                             password=u'password',
...                             project_name=u'demo',
...                             project_domain_name=u'Default')

>>> # Next create a Keystone session using the auth plugin we just created
>>> session = session.Session(auth=auth)

>>> # Now we use the session to create a AutoScaling client
>>> client = client.Client(session=session)

>>> # Then we can access all AutoScaling API
>>> client.groups.get(group_id)
<AutoScalingGroup name= ....>

Note

The example above must be running and configured to use the Keystone Middleware.
