For an explanation about spring cloud config on Spring Cloud Config see http://cloud.spring.io/spring-cloud-config/spring-cloud-config.html
The runtime uses spring cloud config (besides the all the other functionality that spring cloud config uses) for changing/reloading properties. In the configured folder one can place an application.properties
and/or application-debug.properties
(and yaml variants) as the default name is application
(can be configured via spring.application.name=application
).
...
The Runtime uses Spring Cloud Config to be able to load properties from a remote configuration server.
By default the runtime is packaged with an embedded configuration server. This embedded server is configured serve a set of property files located on the file system. Because the server is embedded, the cloud config client does not need to be configured with a remote uri of the configuration server. Instead the client will automatically load its configuration from the embedded config server.
For the embedded config server the following properties are configured:

Properties supplied to the runtime through the config server take precedence over all other property sources. This may be changed by setting one of the following properties:
For any of these properties to have effect, they must be specified in a property file hosted by the config server. For example in See also http://cloud.spring.io/spring-cloud-static/spring-cloud.html#overriding-bootstrap-properties for more information |

Server Config
Spring config server will can run separately and handle the property files. The client will communicate with the server to get the property files.
The property files will either come from the file-system or use GIT.
