Supporting multiple instances

Page last updated:

You can register your service broker with multiple Cloud Foundry instances.

It might 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 and authentication

The broker can use unique credentials, a unique URL, or both for each Cloud Foundry instance. When registering the broker, you can configure different Cloud Foundry instances 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 returns further information, including the location of that Cloud Foundry instance’s UAA.

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