Supporting Multiple Cloud Foundry Instances

It is possible to register a service broker with multiple Cloud Foundry instances. It may be necessary for the broker to know which Cloud Foundry instance is making a given request. For example, when using Dashboard Single Sign-On, the broker is expected to interact with the authorization and token endpoints for a given Cloud Foundry instance.

There are two strategies that can be used to discover which Cloud Foundry instance is making a given request.

Routing & Authentication

The broker can use unique credentials and/or a unique url for each Cloud Foundry instance. When registering the broker, different Cloud Foundry instances can be configured to use different base urls that include a unique id. For example:

• On Cloud Foundry instance 1, the service broker is registered with the url broker.example.com/123
• On Cloud Foundry instance 2, the service broker is registered with the url broker.example.com/456

X-Api-Info-Location Header

All calls to the broker from Cloud Foundry include an X-Api-Info-Location header containing the /v2/info url for that instance. The /v2/info endpoint will return further information, including the location of that Cloud Foundry instance’s UAA.

Support for this header was introduced in cf-release v212.
