consul first bootstrap with spring cloud config

Question

Iam using spring-cloud-config for centralized configuration and consul for service discovery. Like eureka first bootstrap - does spring support consul first bootstrap i.e on booting up a client service - I should look up the config server through consul. The otherway round works perfectly fine i.e - in config client bootstrap.properties - I provide the spring.cloud.config.uri=http://localhost:8888 which located the config server and pulls config from it. And in the config repository for my client application - I provide the consul config like :

spring.cloud.consul.host=localhost , 
spring.cloud.consul.port=8500

However, when i try to use consul first bootstrap I am unable to read the properties from config server.

Client Application (for consul first bootstrap):

pom.xml

            <artifactId>spring-cloud-starter-zuul</artifactId>
        </dependency>
</dependencies>

bootstrap.properties:

spring.application.name=demo
spring.cloud.config.failFast=true
spring.cloud.config.retry.maxAttempts=20
spring.cloud.config.retry.initialInterval=3000
spring.cloud.consul.host=localhost
spring.cloud.consul.port=8500

DemoApplication.java

@EnableDiscoveryClient
@EnableZuulProxy
@SpringBootApplication
public class DemoSleuthApplication {
    public static void main(String[] args) {
        SpringApplication.run(DemoSleuthApplication.class, args);
    }
}
@RefreshScope
@RestController
class RestAPIController 
{
    @Value(value = "${server.port}")
    String port;

    @Value(value = "${message}")
    String message;

@RequestMapping("/message")
      public String welcome(){
          String s = this.restTemplate.getForObject("http://localhost:"+this.port+"/message", String.class);
          return this.message + s;
      }
}

In the consul K/V store folder structure config/demo Key/Value : spring.cloud.config.uri=http://localhost:8888

Config server git repo: not adding the config server code for brevity demo.properties

server.port=9080
message=test

Ideally when I implement the concept of consul first bootstrap - I am thinking consul should be started and the client should identify itself using the @EnableDiscoveryClient annotation and in the consul properties - find config server url , and fetch the config properties from the server configurations. But in my case, service is being discovered and registered in consul but i am not able to read properties from config server git repo.

Answer 1

It was done here. It is available in SNAPSHOTS and in RC2 which will come hopefully next week.

Answer 2

Giving my sample code here for benefit of others. I had to do a lot of tinkering with the properties file to get to this. As answered by @spencergibb it is available in SNAPSHOT only for now.

This time i did not use any key value properties in consul. config server code: pom.xml:

<dependency>
   <groupId>org.springframework.cloud</groupId>
   <artifactId>spring-cloud-config-server</artifactId>
 </dependency>
 <dependency>
     <groupId>org.springframework.cloud</groupId>
     <artifactId>spring-cloud-starter-consul-all</artifactId>
  </dependency>
 <dependency>
   <groupId>org.springframework.cloud</groupId>
   <artifactId>spring-cloud-consul-discovery</artifactId>
 </dependency>

application.yml

     active: native
    cloud:
     config:
       server:

    consul:
      port: 8500
      host: localhost
      enabled: true
      discovery:
        enabled: true
        register: true
        service-name: server --registers in consul as server instead of config-server 
        hostname: localhost
server:
  port: 8888
