Installation

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]:
        pass

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

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

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

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

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

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

# 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)
app.register_blueprint(openbroker_bp)
app.run("0.0.0.0")

Error Types

Openbrokerapi defines a handful of error types in errors.py 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.
