For an explanation on Spring Cloud Config see http://cloud.spring.io/spring-cloud-config/spring-cloud-config.html 

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:

Code Block
spring.profiles.active=native 
spring.cloud.config.server.native.searchLocations=${spring.config.location}
spring.cloud.config.server.bootstrap=true

By specifying the

 property, the location from where property files are read may be changed. At this location an

 may be placed with properties to configure the runtime.

Warning

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:

  • spring.cloud.config.allowOverride=[true|false] (false for lowest priority)
  • spring.cloud.config.overrideNone=[true|false] (true for highest priority)
  • spring.cloud.config.overrideSystemProperties=[true|false] (true for higher priority than system properties, false for lower priority than system 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

Include Page
_PropertiesFileJava
_PropertiesFileJava
in the directory specified by spring.cloud.config.server.native.searchLocations property or in the configured git repository if applicable.

Server Config

Spring config server can Spring config server will 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.

Info

Currently static resources are not managed by the spring cloud config server (for example frontend sources and exports). This may change in a future release.
