Example Apps Overview

This doc provides an overview of the example apps provided and the uses cases they provide.

Use Cases

• general network debugging
• use container-to-container networking
• use container-to-container networking with service discovery
• use Eureka for service discovery
• use an a8registry

---

Use case: you want an app to do network debugging

App: Proxy

Description: Proxy has endpoints for using dig and ping, for showing stats, uploading and downloading an arbitrary number of bytes, and more. It is a good app for general debugging purposes.

Use case: you want to try out container-to-container networking

App: Cats and Dogs

Description: This example demonstrates container-to-container networking via HTTP and UDP between a frontend and backend app.

Use case: you want to try out container-to-container networking with service discovery

App: Cats and Dogs with Service Discovery

Description: This example demonstrates container-to-container networking via HTTP and UDP between a frontend and backend app with service discovery.

Use case: you want to try out Eureka for service discovery

App: Spring Boot Eureka Demo

Description: This example demonstrates how apps can use Eureka for service discovery for container-to-container communications. Using Eureka was a popular method before platform service discovery was added to Cloud Foundry.

Use case: you want to use an a8registry

App: tick

Description: This is a simple app that registers itself with an a8registry on a regular interval.
