interpolateServiceData
Search the provided data structure of bound service credentials, looking for references to CredHub credentials. Any CredHub credentials found in the data structure will be replaced by the credential value stored in CredHub. Example: A JSON data structure parsed from a VCAP_SERVICES environment variable might look like this if the service broker that provided the binding is integrated with CredHub:
Assuming that CredHub has a credential with the name /c/service-broker/service-offering/1111-2222-3333-4444/credentials, passing the data structure above to this method would result in the credhub-ref field being replaced by the credentials stored in CredHub:{ "service-offering": [{ "credentials": { "credhub-ref": "((/c/service-broker/service-offering/1111-2222-3333-4444/credentials))" } "label": "service-offering", "name": "service-instance", "plan": "standard", "tags": [" "cloud-service" ] }] }{ "service-offering": [{ "credentials": { "url": "https://servicehost.example.com/", "username": "someuser", "password": "secret" } "label": "service-offering", "name": "service-instance", "plan": "standard", "tags": [" "cloud-service" ] }] }- Parameters:
serviceData- a data structure of bound service credentials, as would be parsed from the VCAP_SERVICES environment variable provided to applications running on Cloud Foundry- Returns:
- the serviceData structure with CredHub references replaced by stored credential values
