heroku3 4.2.0

Heroku API Wrapper.

Heroku3.py

This is the updated Python wrapper for the Heroku API V3. 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.

Introduction

First instantiate a heroku_conn as above:

import heroku3
heroku_conn = heroku3.from_key('YOUR_API_KEY')

Interact with your applications:

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

>>> app = heroku_conn.apps()['sharp-night-7758']

General notes on Debugging

Heroku provides some useful debugging information. This code exposes the following

Ratelimit Remaining

Get the current ratelimit remaining:

num = heroku_conn.ratelimit_remaining()

Last Request Id

Get the unique ID of the last request sent to heroku to give them for debugging:

id = heroku_conn.last_request_id

General notes about list Objects

The new heroku3 API gives greater control over the interaction of the returned data. Primarily this centres around calls to the api which result in list objects being returned. e.g. multiple objects like apps, addons, releases etc.

Throughout the docs you’ll see references to using limit & order_by. Wherever you see these, you should be able to use limit, order_by, sort and valrange.

You can control ordering, limits and pagination by supplying the following keywords:

order_by=<'id'|'version'>
limit=<num>
valrange=<string> - See api docs for this, This value is passed straight through to the API call *as is*.
sort=<'asc'|'desc'>

You’ll have to investigate the api for each object’s *Accept-Ranges* header to work out which fields can be ordered by

Examples

List all apps in name order:

heroku_conn.apps(order_by='name')

List the last 10 releases:

app.releases(order_by='version', limit=10, sort='desc')
heroku_conn.apps()['empty-spring-4049'].releases(order_by='version', limit=10, sort='desc')

List objects can be referred to directly by any of their primary keys too:

app = heroku_conn.apps()['myapp']
dyno = heroku_conn.apps()['myapp_id'].dynos()['web.1']
proc = heroku_conn.apps()['my_app'].process_formation()['web']

Be careful if you use *limit* in a list call *and* refer directly to an primary key E.g.Probably stupid…:

dyno = heroku_conn.apps()['myapp'].dynos(limit=1)['web.1']

General Notes on Objects

To find out the Attributes available for a given object, look at the corresponding Documentation for that object. e.g.

Formation Object:

>>>print(feature.command)
bundle exec rails server -p $PORT

>>>print(feature.created_at)
2012-01-01T12:00:00Z

>>>print(feature.id)
01234567-89ab-cdef-0123-456789abcdef

>>>print(feature.quantity)
1
>>>print(feature.size)
1
>>>print(feature.type)
web

>>>print(feature.updated_at)
2012-01-01T12:00:00Z

Switching Accounts Mid Flow

It is also possible to change the underlying heroku_connection at any point on any object or listobject by creating a new heroku_conn and calling change_connection:

heroku_conn1 = heroku3.from_key('YOUR_API_KEY')
heroku_conn2 = heroku3.from_key('ANOTHER_API_KEY')
app = heroku_conn1.apps()['MYAPP']
app.change_connection(heroku_conn2)
app.config() # this call will use heroku_conn2
## or on list objects
apps = heroku_conn1.apps()
apps.change_connection(heroku_conn2)
for app in apps:
    config = app.config()

Legacy API Calls

The API has been built with an internal legacy=True ability, so any functionlity not implemented in the new API can be called via the previous legacy API. This is currently only used for rollbacks.

Object API

Account

Get account:

account = heroku_conn.account()

Change Password:

account.change_password("<current_password>", "<new_password>")

SSH Keys

List all configured keys:

keylist = account.keys(order_by='id')

Add Key:

account.add_key(<public_key_string>)

Remove key:

account.remove_key(<public_key_string - or fingerprint>)

Account Features (Heroku Labs)

List all configured account “features”:

featurelist = account.features()

Disable a feature:

feature = account.disable_feature(id_or_name)
feature.disable()

Enable a feature:

feature = account.enable_feature(id_or_name)
feature.enable()

Plans - or Addon Services

List all available Addon Services:

addonlist = heroku_conn.addon_services(order_by='id')
addonlist = heroku_conn.addon_services()

Get specific available Addon Service:

addonservice = heroku_conn.addon_services(<id_or_name>)

App

The App Class is the starting point for most of the api functionlity.

List all apps:

applist = heroku_conn.apps(order_by='id')
applist = heroku_conn.apps()

Get specific app:

app = heroku_conn.app(<id_or_name>)
app = heroku_conn.apps()[id_or_name]

Create an app:

app = heroku_conn.create_app(name=None, stack_id_or_name='cedar', region_id_or_name=<region_id>)

Destroy an app (Warning this is irreversible):

app.delete()

Addons

List all Addons:

addonlist = app.addons(order_by='id')
addonlist = applist[<id_or_name>].addons(limit=10)
addonlist = heroku_conn.addons(<app_id_or_name>)

Install an Addon:

addon = app.install_addon(plan_id_or_name='<id>', config={})
addon = app.install_addon(plan_id_or_name='<name>', config={})
addon = app.install_addon(plan_id_or_name=addonservice.id, config={})
addon = app.install_addon(plan_id_or_name=addonservice.id, config={}, attachment_name='ADDON_ATTACHMENT_CUSTOM_NAME')

Remove an Addon:

addon = app.remove_addon(<id>)
addon = app.remove_addon(addonservice.id)
addon.delete()

Update/Upgrade an Addon:

addon = addon.upgrade(plan_id_or_name='<name>')
addon = addon.upgrade(plan_id_or_name='<id>')

Buildpacks

Update all buildpacks:

buildpack_urls = ['https://github.com/some/buildpack', 'https://github.com/another/buildpack']
app.update_buildpacks(buildpack_urls)

N.B. buildpack_urls can also be empty. This clears all buildpacks.

App Labs/Features

List all features:

appfeaturelist = app.features()
appfeaturelist = app.labs() #nicename for features()
appfeaturelist = app.features(order_by='id', limit=10)

collaborator = app.add_collaborator(user_id_or_email=<valid_email>, silent=0)
collaborator = app.add_collaborator(user_id_or_email=user_id, silent=0)
collaborator = app.add_collaborator(user_id_or_email=user_id, silent=1) #don't send invitation email

Remove a Collaborator:

collaborator = app.remove_collaborator(userid_or_email)

ConfigVars

Get an apps config:

config = app.config()

Add a config Variable:

config['New_var'] = 'new_val'

Update a config Variable:

config['Existing_var'] = 'new_val'

Remove a config Variable:

del config['Existing_var']
config['Existing_var'] = None

Update Multiple config Variables:

# newconfig will always be a new ConfigVars object representing all config values for an app
# i.e. there won't be partial configs
newconfig = config.update({u'TEST1': u'A1', u'TEST2': u'A2', u'TEST3': u'A3'})
newconfig = heroku_conn.update_appconfig(<app_id_or_name>, {u'TEST1': u'A1', u'TEST2': u'A2', u'TEST3': u'A3'})
newconfig = app.update_config({u'TEST1': u'A1', u'TEST2': u'A2', u'TEST3': u'A3'})

Check if a var exists:

if 'KEY' in config:
    print("KEY = {0}".format(config[KEY]))

Get dict of config vars:

my_dict = config.to_dict()

Domains

Get a list of domains configured for this app:

domainlist = app.domains(order_by='id')

Add a domain to this app:

domain = app.add_domain('domain_hostname')

Remove a domain from an app:

domain = app.remove_domain('domain_hostname')

Dynos & Process Formations

Dynos

Dynos represent all your running dyno processes. Use dynos to investigate whats running on your app. Use Dynos to create one off processes/run commands.

You don’t “scale” dyno Processes. You “scale” Formation Processes. See Formations section Below

Get a list of running dynos:

dynolist = app.dynos()
dynolist = app.dynos(order_by='id')

Kill a dyno:

app.kill_dyno(<dyno_id_or_name>)
app.dynos['run.1'].kill()
dyno.kill()

Restarting your dynos is achieved by killing existing dynos, and allowing heroku to auto start them. A Handy wrapper for this proceses has been provided below.

N.B. This will only restart Formation processes, it will not kill off other processes.

Restart a Dyno:

#a simple wrapper around dyno.kill() with run protection so won't kill any proc of type='run' e.g. 'run.1'
dyno.restart()

Restart all your app’s Formation configured Dyno’s:

app.restart()

Run a command without attaching to it. e.g. start a command and return the dyno object representing the command:

dyno = app.run_command_detached('fab -l', size=1, env={'key': 'val'})
dyno = heroku_conn.run_command_on_app(<appname>, <command>, size=1, attach=False, printout=True, env={'key': 'val'})

Run a command and attach to it, returning the commands output as a string:

#printout  is used to control if the task should also print to STDOUT - useful for long running processes
#size = is the processes dyno size 1X(default), 2X, 3X etc...
#env = Envrionment variables for the dyno
output, dyno = heroku_conn.run_command_on_app(<appname>, <command>, size=1, attach=True, printout=True, env={'key': 'val'})
output = app.run_command('fab -l', size=1, printout=True, env={'key': 'val'})
print output

Formations

Formations represent the dynos that you have configured in your Procfile - whether they are running or not. Use Formations to scale dynos up and down

Get a list of your configured Processes:

proclist = app.process_formation()
proclist = app.process_formation(order_by='id')
proc = app.process_formation()['web']
proc = heroku_conn.apps()['myapp'].process_formation()['web']

Scale your Procfile processes:

app.process_formation()['web'].scale(2) # run 2 dynos
app.process_formation()['web'].scale(0) # don't run any dynos
proc = app.scale_formation_process(<formation_id_or_name>, <quantity>)

Resize your Procfile Processes:

app.process_formation()['web'].resize(2) # for 2X
app.process_formation()['web'].resize(1) # for 1X
proc = app.resize_formation_process(<formation_id_or_name>, <size>)

Log Drains

List all active logdrains:

logdrainlist = app.logdrains()
logdrainlist = app.logdrains(order_by='id')

Create a logdrain:

loggdrain = app.create_logdrain(<url>)

Remove a logdrain:

delete_logdrain - app.remove_logdrain(<id_or_url>)

Log Sessions

Access the logs:

log = heroku_conn.get_app_log(<app_id_or_name>, dyno='web.1', lines=2, source='app', timeout=False)
log = app.get_log()
log = app.get_log(lines=100)
print(app.get_log(dyno='web.1', lines=2, source='app'))
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

You can even stream the tail:

#accepts the same params as above - lines|dyno|source|timeout (passed to requests)
log = heroku_conn.stream_app_log(<app_id_or_name>, lines=1, timeout=100)
#or
for line in app.stream_log(lines=1):
     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

Maintenance Mode

Enable Maintenance Mode:

app.enable_maintenance_mode()

Disable Maintenance Mode:

app.disable_maintenance_mode()

OAuth

OAuthAuthorizations

List all OAuthAuthorizations:

authorizations = heroku_conn.oauthauthorizations(order_by=id)

Get a specific OAuthAuthorization:

authorization = authorizations[<oauthauthorization_id>]
authorization = heroku_conn.oauthauthorization(oauthauthorization_id)

Create an OAuthAuthorization:

authorization = heroku_conn.oauthauthorization_create(scope, oauthclient_id=None, description=None)

Delete an OAuthAuthorization:

authorization.delete()
heroku_conn.oauthauthorization_delete(oauthauthorization_id)

OAuthClient

List all OAuthClients:

clients = heroku_conn.oauthclients(order_by=id)

Get a specific OAuthClient:

client = clients[<oauthclient_id>]
client = heroku_conn.oauthclient(oauthclient_id)

Create an OAuthClient:

client = heroku_conn.oauthclient_create(name, redirect_uri)

Update an existing OAuthClient:

client = client.update(name=None, redirect_uri=None)

Delete an OAuthClient:

client.delete()
heroku_conn.oauthclient_delete(oauthclient_id)

OAuthToken

Create an OAuthToken:

heroku_conn.oauthtoken_create(client_secret=None, grant_code=None, grant_type=None, refresh_token=None)

Release

List all releases:

releaselist = app.releases()
releaselist = app.releases(order_by='version')

Release information:

for release in app.releases():
    print("{0}-{1} released by {2} on {3}".format(release.id, release.description, release.user.name, release.created_at))

Rollback to a release:

app.rollback(release.id)
app.rollback("489d7ce8-1cc3-4429-bb79-7907371d4c0e")

Rename App

Rename App:

app.rename('Carrot-kettle-teapot-1898')

Customized Sessions

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

Logging

Note: logging is now achieved by the following method:

import httplib
httplib.HTTPConnection.debuglevel = 1

logging.basicConfig() # you need to initialize logging, otherwise you will not see anything from requests
logging.getLogger().setLevel(logging.INFO)
requests_log = logging.getLogger("requests.packages.urllib3")
requests_log.setLevel(logging.INFO)
requests_log.propagate = True

heroku_conn.ratelimit_remaining()
