CRUD-Microservices

==========================================

This is a example project using Netflix OSS technologies to build Microservices that will run at AWS cloud.

Frameworks/Tools	-	-
Maven	Netflix Governator	Google Guava
Java 8	Netflix Karyon	jUnit
Google Guice	Netflix Hystrix	AngularJS
Jersey	Netflix Eureka	Bootstrap
Jackson	Netflix Archaius	Less
Cassandra	Netflix Ribbon	Bower
RxJava	Netflix EVCache	NPM

Running with Docker

The docker-compose file starts everything needed to have the 'crudmicroservices' up and running. First we have to build the project and generate the images for each service, for this just run the script build-docker-images

$ sh build-docker-images.sh

Having it done we are ready to start all of services (ServiceDiscovery, APIGateway, EdgeService, MiddleService, Cassandra..)

$ docker-compose up

This single line command will start everything, just wait a moment (+/- 1 min).

Scaling Up

$ docker-compose scale {serviceName}={numberOfInstances} ...

Once started we can verify the Up services at Eureka console: Eureka Console

The API Gateway can be reached at: Zuul

Requests can be sent to the Gateway: http://localhost:9090/crudmicroservicesedge
