eu.europeana.corelib.web.context.VcapPropertyLoaderListener

public class VcapPropertyLoaderListener
extends org.springframework.boot.cloudfoundry.VcapApplicationListener

Bridge between the VCAP (a.k.a. Cloud Foundry) metadata (specifically, the VCAP_APPLICATION and VCAP_SERVICES metadata) and the europeana.properties file (part of the war).This reads the europeana.properties file (found on the classpath), and will inject and CF environment variables to make them accessible to the application. The following properties will be replaced, or added if they don't exist yet, using values from the system-provided environment variables, if they are listed as user-provided variables.

 postgres.*
 mongodb.*
 

In other words, adding 'mongo_service: europeana-object-db-blue-2' to the env section of the manifest.yaml, will replace/add all mongodb.* values found in the europeana properties with the CF system provided ones. To use the Postgres values, use 'postgres_service: default' The following system-provided properties will _always_ be injected, if it exists in the system environment:

 redis.*
 

And the following user-provided properties, if they exist, will also be added to the europeana.properties:

 api2_url
 api2_canonical_url
 portal_server
 portal_server_canonical
