But there is also a good integration for client applications written with Spring Boot. And because Grails (3) depends on Spring Boot we can leverage the same integration support. Because of the Spring Boot auto configuration we only have to add a dependency to our build file and add some configuration.

Before we look at how to use a Spring Cloud Config server in our Grails application we start our own server for testing. We use a local Git repository as backend for the configuration. And we use the Spring Boot CLI to start the server. We have the following Groovy source file to enable the configuration server:
