Heroku.py

This is an awesome Python wrapper for the Heroku API. The Heroku REST API allows Heroku users to manage their accounts, applications, addons, and other aspects related to Heroku. It allows you to easily utilize the Heroku platform from your applications.

Usage

Login with your password:

import heroku
cloud = heroku.from_pass('[email protected]', 'xxxxxxx')

Or your API Key (available here):

cloud = heroku.from_key('YOUR_API_KEY')

Interact with your applications:

>>> cloud.apps
[<app 'sharp-night-7758'>, <app 'empty-spring-4049'>, ...]

>>> app = cloud.apps['sharp-night-7758']

Scale them up:

>>> app.processes
[<process 'web.1'>, <process 'worker.1'>]

>>> app.processes['web']
[<process 'web.1'>]

>>> app.processes['web'].scale(3)
[<process 'web.1'>, <process 'web.2'>, <process 'web.3'>]

>>> app.processes[0].stop()
True

Access the logs:

>>> print app.logs(num=2)
2011-12-21T22:53:47+00:00 heroku[web.1]: State changed from down to created
2011-12-21T22:53:47+00:00 heroku[web.1]: State changed from created to starting

>>> print app.logs(num=2, tail=True)
<generator object stream_decode_response_unicode at 0x101151d20>

You can even stream the tail:

>>> for line in app.logs(tail=True):
...     print line

2011-12-21T22:53:47+00:00 heroku[web.1]: State changed from down to created
2011-12-21T22:53:47+00:00 heroku[web.1]: State changed from created to starting
...

Change app configration:

>>> app.config['DEBUG'] = 1
>>> app.config
{u'DEBUG': 1, u'PATH': u'bin:/usr/local/bin:/usr/bin:/bin', u'PYTHONUNBUFFERED': True}

>>> del app.config['DEBUG']

See release history:

>>> app.releases
[<release 'v1'>, <release 'v2'>, ..., <release 'v84'>]


>>> release = app.releases[-2]
>>> release.name
v84

>>> release.env
{u'PATH': u'bin:/usr/local/bin:/usr/bin:/bin', u'PYTHONUNBUFFERED': True}

>>> release.pstable
{u'web': u'gunicorn httpbin:app -b "0.0.0.0:$PORT"'}

>>> release.addons
[u'blitz:250', u'custom_domains:basic', u'logging:basic', u'releases:advanced']

>>> release.rollback()
<release 'v85'>

Create a new app:

>>> cloud.apps.add('myapp')
<app 'myapp'>

Delete the app completely:

>>> app.destroy()
True

And much more. Detailed docs forthcoming.

Customized Sessions

Heroku.py is powered by Requests and supports all customized sessions:

For example advanced logging for easier debugging:

>>> import sys
>>> import requests
>>> from heroku.api import Heroku

>>> my_config = {'verbose': sys.stderr}
>>> session = requests.session(config=my_config)
>>> cloud = Heroku(session=session)
>>> cloud.authenticate(cloud.request_key('[email protected]', 'xxxxxxx'))
>>> cloud.apps
2011-12-21T22:53:47+00:00   GET   https://api.heroku.com/apps
[<app 'myapp'>]

Installation

To install heroku.py, simply:

$ pip install heroku

Or, if you absolutely must:

$ easy_install heroku

But, you really shouldn't do that.
