Owncloud Spring Cloud Example

The goal of this Project is to show the Combination of

• Spring Cloud Config Server
• Spring Cloud Eureka Service Registry
• Spring Cloud Feign (included Hystrix and Ribbon)
• Spring Cloud Turbine
• Spring Cloud Hystrix Dashboard
• Docker
• Docker Compose

Installation

Run mvn -P withDocker clean install. After a successful Build the following Docker Images have been created

Docker Image	Description
mufasa1976/spring-cloud-example-configserver	Configuration Server
mufasa1976/spring-cloud-example-eureka	Eureka Service Discovery
mufasa1976/spring-cloud-example-service	internal Service
mufasa1976/spring-cloud-example-turbine	User Endpoint and Hystrix Dashboard

After this you can start the whole Application by ./docker-compose.sh.
This little Shell-Scripts starts all neccessary Containers in the correct Order and waits until the Application is up and running.

Try it out

Start the Application with a simple Shell-Script ./docker-compose.sh.
This Shell-Script starts all neccessary Containers in the correct Order.

The Application has a simple REST-Endpoint GET localhost:8080/hint which will print the Text There is a Hint.

$> curl localhost:8080/hint
There is a Hint

Maybe the first Time there will be an Error (Timeout with no fallback). But the second Time you try the Feign-Proxy has been successfully created and you will see the expected Result.

Shut down the Application with docker-compose down.

Monitor

The Hystrix Metrics will be aggregated by Turbine. This aggregated Stream will be available right after the Feign-Proxy has been created.

The Hystrix-Dashboard is available under http://localhost:8080/hystrix.
The Stream-URL then is http://turbine:8080/turbine.stream

Eureka is available by http://localhost:8761.
