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