PCF 17 - Route Services

Route Services

• What is a route service?

  Route Services are a kind of Marketplace Service that developers can use to apply various transformations to application requests by binding an application’s route to a service instance.

• Why might you create a route service? Can you think of some examples?

  Provide transformation or processing to requests before/after they reach an application Examples:

  • Authentication
  • Rate limiting
  • Logging
  • Caching
  • Transformation
• How would you create a route service?

  cf create-user-provided-service SERVICE-INSTANCE -r ROUTE-SERVICE-URL

  cf bind-route-service [domain-name] [route-service-name] --hostname [target-hostname]

• How does a route service work?

  Binding a service instance to a route associates the route_service_url with the route in the Cloud Foundry router. All requests for the route are proxied to the URL specified by route_service_url

• How does a route service know where to send a request once it has performed its function?

  With the Headers

  • X-CF-Forwarded-URL
  • X-CF-Proxy-Signature
  • X-CF-Proxy-Metadata

  Used by the Router to validate the request and pass through to the application or reject it.
