Service Broker API

A Python package for building Service Brokers supporting API version 2.10+.

Following CF Service Broker API and Open Service Broker API


This package is available for Python 3.6+.

pip3 install openbrokerapi

Or install the development version from github:

pip3 install git+

Getting started

from flask import Flask
from openbrokerapi import service_broker
from openbrokerapi.api import *
from openbrokerapi.log_util import *

# Implement a service broker by overriding methods of ServiceBroker
class CustomServiceBroker(service_broker.ServiceBroker):
    def catalog(self) -> List[Service]:

    def provision(self, instance_id: str, service_details: ProvisionDetails, async_allowed: bool) -> ProvisionedServiceSpec:

    def unbind(self, instance_id: str, binding_id: str, details: UnbindDetails):

    def update(self, instance_id: str, details: UpdateDetails, async_allowed: bool) -> UpdateServiceSpec:

    def bind(self, instance_id: str, binding_id: str, details: BindDetails) -> Binding:

    def deprovision(self, instance_id: str, details: DeprovisionDetails, async_allowed: bool) -> DeprovisionServiceSpec:

    def last_operation(self, instance_id: str, operation_data: str) -> LastOperation:

# Simpely start the server
serve(CustomServiceBroker(), BrokerCredentials("", ""))

# or register blueprint to your own FlaskApp instance
app = Flask(__name__)
logger = basic_config() #  Use root logger with a basic configuration provided by openbrokerapi.log_utils
openbroker_bp = get_blueprint(CustomServiceBroker(), BrokerCredentials("",""), logger)

Error Types

Openbrokerapi defines a handful of error types in for some common error cases that your service broker may encounter. Raise these from your ServiceBroker methods where appropriate, and openbrokerapi will do the “right thing” (™), and give Cloud Foundry an appropriate status code, as per the Service Broker API specification.
