Start Up Eureka Service Discovery In Spring Boot

Today , we are going to see Spring Boot Eureka Server Configuration  in STS  :

Step 1: Create Spring Starter Project in Spring Tool Suite :

Step 2: Do Java,Maven Configuration as below :

Step 3 : select Dependencies Eureka Discovery Client and Eureka Server

Step 4 : click Next - > Finish

Step 5 : Once all dependencies downloaded successfully , then add annotation @EnableEurekaServer on main class as below :

Step 6 : Edit Properties file as below :

	server.port=8001
	spring.application.name=discoveryservice
	eureka.client.registerWithEureka=false
	eureka.client.fetchRegistry=false
	eureka.client.serviceUrl.defaultZone= http://localhost:8001/eureka

Step 7: Run main class as spring boot app :

Step 8 : Once Application started succesfuly check in browser :

             now visit url : http://localhost:8001/ it will show UI as below  :

Finally our Eureka Server started as shown above ,lets understand properties in application.properties file in more details : 

1> eureka.client.registerWithEureka : 

its default value is true : we have given as false :

registerWithEureka Indicates whether or not this instance should register its information with eureka server for discovery by others. In some cases, you do not want your instances to be discovered whereas you just want do discover other instances.

2>eureka.client.fetchRegistry :

its default value is true , fetchRegistry  Indicates whether this client should fetch eureka registry information from eureka server.

3>eureka.client.serviceUrl.defaultZone :

Map of availability zone to list of fully qualified URLs to communicate with eureka server. Each value can be a single URL or a comma separated list of alternative locations. Typically the eureka server URLs carry protocol,host,port,context and version information if any. 

Example: https://ec2-256-156-243-129.compute-1.azaws.com:7001/eureka/ .
