Steps to develop Service Registry Application (Eureka Server)
===============================================================

1) Create SpringBoot application with below dependency

	 - Eureka Server (spring-cloud-starter-netflix-eureka-server)
	 - devtools

2) Configure @EnableEurekaServer annotation in boot start class

3) Configure below properties in application.yml file

spring:
  application:
    name: 01_Service_Registry
server:
  port: 8761
eureka:
  client:
    register-with-eureka: false	


Note-1: If "Service-Registry" project port is 8761 then clients can discover "service-registry" and will register automatically with service-registry. 

Note-2 : If service-registry project running on any other port number then we have to register clients with service-registry manually.

4) Once application started we can access Eureka Dashboard using below URL

		URL : http://localhost:8761/


======================================
Steps to develop Spring Admin-Server
======================================

1) Create Boot application with "admin-server" dependency 
  (select it while creating the project)

2) Configure @EnableAdminServer annotation at start class 

3) Change Port Number (Optional)

spring:
  application:
    name: 02_Admin_Server
server:
  port: 1111


4) Run the boot application

5) Access application URL in browser (We can see Admin Server UI)

    URL : http://localhost:1111/    


======================================
Steps to work with Zipkin Server
======================================    

1) Download Zipin Jar file 

    URL : https://zipkin.io/pages/quickstart.html

2) Run zipkin jar file 

    $ java -jar <jar-name>    

3) Zipkin Server Runs on Port Number 9411 

4) Access zipkin server dashboard

    URL : http://localhost:9411/
