Cross The Streams - SpringOne 2020

👋 Getting Started

The following tools will be helpful to hack on the project:

1. SDKMAN! (JDK version manager)
2. kind (quickly setup a local Kubernetes cluster)
3. JMeter (performance testing harness)

Repository Layout

This repository has two branches:

1. main - this branch is the starting point for the coding demo
2. graceful-shutdown-support - this branch contains the changes made to the codebase to support graceful shutdowns during the demo

Deploying The Application

1. Install Java 11

   sdk install java 11.0.2-open

2. Create a Kubernetes cluster with kind

   kind create cluster --config kind.config.yaml

3. Build the Docker image:

   ./gradlew jibDockerBuild

4. Load the Docker image into the kind cluster:

   kind load docker-image cross-the-streams:0.0.1
   

5. Deploy to the kind cluster:

   kubectl apply -f k8s/

6. Access the /speakers REST API:

   curl -i http://localhost:8080/speakers

7. Launch JMeter and open cross-the-streams.jmx
