Eureka-Server with spring cloud netflix

In this write-up we will focus on

Service Registry – Eureka Server
Rest service (auth-service application, eureka client) which register itself to registry.
Web application which consumes Rest service using service registry.

Service discovery allows services to find and communicate with each other without hardcoding hostname and port.

Eureka Server

In spring-boot application enable the Eureka-Server by adding @EnableEurekaServer annotation to spring boot application.

We have put all the configuration on GIT and this is accessed using config-server. To now more about centralized configuration (config-server) click here

eurekaserver.yml

Place below bootstrap.yml in application, it basically connects to config-server and gets it required configuration.

Start the spring-boot application and access eureka server using http://localhost:8760/ you will get below screen.

Right now there is no application which is registered to eureka-server. Once you start the application which is register to eureka-server you will start seeing application name, its status, availability zone etc in eureka sever.

Note: We have not yet secured eureka-server with userid/password.

Cheers – Happy learning 🙂
