Supporting Multiple PAS Instances
Page last updated:
This topic describes registering a service broker with multiple Pivotal Application Service (PAS) instances.
It may be necessary for the broker to know which PAS 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 PAS instance.
There are two strategies that can be used to discover which PAS instance is making a given request.
The broker can use unique credentials, a unique URL, or both for each PAS instance. When registering the broker, you can configure different PAS instances to use different base URLs that include a unique ID. For example:
On PAS instance 1, the service broker is registered with the URL
On PAS instance 2, the service broker is registered with the URL
All calls to the broker from PAS 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 PAS instance’s UAA.
Support for this header was introduced in cf-release v212.
