I have configured eureka with below properties in its application properties:

  • spring.application.name=eureka.azurewebsites.net
  • eureka.client.registerWithEureka=false
  • eureka.client.fetchRegistry=false
  • eureka.instance.hostname=eureka.azurewebsites.net
  • eureka.client.serviceUrl.defaultZone=http://${eureka.instance.hostname}:${server.port}/eureka/

Service1 in azure:

Service 2 in azure:

Now when i try to call rest api from service 1 to another service 2 using restTemplate i get unknowhost exception:

Below is the code snippet:
URI uri = new URI("http://service2.azurewebsites.net/receiverGET");
result = restTemplate.getForObject(uri, String.class);

I know it is not issue buti am not able to call service 2 from service via eureka (I am new to microservice + azure deployment). Any help or pointers will help. This is primarily because azure generates IP and port number dynamically.

I'm afraid that is not enough information to help diagnosing your problem. Does service 1 and 2 show up in the eureka dashboard?

Yes It does show up. Both services are registered in eureka.

How is the RestTemplate object created? From your example I am not even sure you are taking advantage of Eureka.

Also, what version are you using (what release train)?

I actually created restTemplate using:

@RestController
@EnableAutoConfiguration
@componentscan
@SpringBootApplication
@EnableDiscoveryClient
public class Service2 {

   private static final Logger LOG = LoggerFactory.getLogger(PLMBommsApplication.class);

   @Bean
   RestTemplate restTemplate() {
         return new RestTemplate();
   }

   @Autowired
   RestTemplate restTemplate;

   @RequestMapping(value = "/")
   public StringBuilder fromCall() throws URISyntaxException {

         StringBuilder response = new StringBuilder();
          URI uri = new URI("http://plm-part-ms.azurewebsites.net/receiverPOST");
         MultiValueMap<String, Object> mvm = new LinkedMultiValueMap<String, Object>();
         mvm.add("abc", "Hello Part");
         result = restTemplate.postForObject(uri, mvm, String.class);
         response.append("successPost = " + result);
         response.append("\n");
         return response;

         }
   public static void main(String[] args) {

         SpringApplication.run(Service2.class, args);

   }

You are correct when you mention that I am not leveraging eureka, I am not able to figure out from tutorials as to where to start it from.

According to the documentation you need to annotate your rest template with @LoadBalanced.

As soon as I add @LoadBalanced the application which is deployed as webapp doesnot start and I get 500 exception

If it does not start what is the exception you are getting?

I know that this is not bug :) but I need some help to get this working as I am new to microservices architecture (I am getting lost in all sorts of documentation available online). Apologies for bothering you people but any help is appreciated !

I know that this is not bug :) but I need some help to get this working as I am new to microservices architecture (I am getting lost in all sorts of documentation available online). Apologies for bothering you people but any help is appreciated !

I have corrected the code and posted the same in stack over flow: https://stackoverflow.com/questions/38941781/java-lang-illegalstateexception-no-instances-available-for-ip

Any suggestions will help.

Slight correction:

I fixed that issue and it is starting now. But the service 1 when trying to do get request (using resttemplate) gets below exception:

@RestController
@EnableAutoConfiguration
@componentscan
@SpringBootApplication
@EnableEurekaClient
public class Service1 {

   private static final Logger LOG = LoggerFactory.getLogger(Service1.class);

   @Bean
   @LoadBalanced
   RestTemplate restTemplate() {
         return new RestTemplate();
   }

   @Autowired
   RestTemplate restTemplate;

   @RequestMapping(value = "/")
   public @ResponseBody StringBuilder fromCall() throws URISyntaxException {
         StringBuilder response = new StringBuilder();
         String result = null;
         LOG.info("Starting to send to Part Microservice==============>>>");
         LOG.info("Starting call====>");
         try {
                // URI("https://controlspartms.scm.azurewebsites.net/receiverPOST");
                // URI uri = new
                // URI("http://plm-part-ms.azurewebsites.net/receiverPOST");
                MultiValueMap<String, Object> mvm = new LinkedMultiValueMap<String, Object>();
                mvm.add("abc", "Hello Service2");
                result = restTemplate.getForObject("http://service2/receiverGet", mvm, String.class);

@SantoshCups does the response on SO help? Might want to respond back there, I am not sure anyone here has any experience using Azure.

Hi, I too am using Azure with Spring Cloud.

I have similar setting as @SantoshCups .

With two more setting in application.properties
hystrix.command.default.execution.timeout.enabled = false
hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds: 60000

But I get the below error:

When I am running in my local pointing eureka and config server as local, I do not have any problem.

The problem is only when I goto Azure.

Looks like it is ribbon timing out, try setting the ribbon request timeout

Hi, I too am using Azure with Spring Cloud.

I have similar setting as @SantoshCups https://github.com/SantoshCups .

With two more setting in application.properties
hystrix.command.default.execution.timeout.enabled = false
hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds:
60000

But I get the below error:

I tried
ribbon.ReadTimeout=30000.
I think this is because Azure uses IP address with Dynamic Port. Is there any app setting?

Just switch to Loadbalanced resttemplate and you will realise that it is not able to hit the microservice registered with eureka due to dynamic IP generation..

Also I tried using the property in eureka:

eureka.instance.prefer-ip-address=false

This doesnot seem to work.. (Group will know lot of other things since I stopped here).. Please let me know if something else works..

On Azure we need to put webapps all under one virtual network. I did not try this and we went over to using docker containers..

Sincerely,
Santosh Kumar U P

Solved !!
After some trial and error:

eureka.instance.prefer-ip-address=false
eureka.instance.non-secure-port=80

The above set of configs for all Clients shall work.
This is because the port 80 in azure in redirected to the site itself. This work around shall work for all azure Websites running as client-server for Eureka.
