A Spring Cloud configuration server is built on the top of a regular Spring Boot application. All you need to do is add the following additional dependency:

compile('org.springframework.cloud:spring-cloud-config-server')

Once the dependency has been added, you need to activate the configuration server using an additional annotation in the application, as shown in the following code:

@SpringBootApplication
@EnableConfigServer
public class ConfigServerApplication 
{
  public static void main(String[] args) 
  {
    SpringApplication.run(ConfigServerApplication.class, args);
  }
}

Finally, you need to provide the Git repository URL, which stores the configuration for your microservices in the application.yaml file, as follows:

spring:
  cloud:
    config:
      server:
        git:
          uri: https://github.com/enriquezrene/spring-architectures-config-server.git

The preceding Git repository has separate configuration files to manage the configuration for each microservice. For example, the configuration-demo.properties file is used to manage the configuration for the configuration demo microservice.
