JKube Hello World Sample

This is a demo project for getting started with Eclipse JKube. It starts a simple HTTP server on port 8080. Performing a request to /hello endpoint will reply with "Hello World". We will be using Eclipse JKube for building a docker image and deploying to Kubernetes with a single command.

Prerequisites

• Java 8+
• Maven
• Minikube
• JKube

Deploying Demo app to Kubernetes with JKube

1. Make sure you've Minikube up and running.

   minikube start

2. Configure your local environment to re-use the Docker daemon inside the Minikube instance.

    $ eval $(minikube -p minikube docker-env) 

3. Run the following command to run and deploy hello-world demo app to Kubernetes

   $ mvn clean install k8s:build k8s:resource k8s:apply

4. Check logs of the created Pod

   $ kubectl get pods
   NAME                          READY   STATUS    RESTARTS   AGE
   helloworld-664bf5fdff-2bmrt   1/1     Running   0          9s
   

5. Log the running Kubernetes services

   $ kubectl get svc
   helloworld   NodePort    10.110.92.145   <none>        8080:32353/TCP   58m
   kubernetes   ClusterIP   10.96.0.1       <none>        443/TCP          7h

6. Call the /hello endpoint

   $ curl `minikube ip`:32353/hello
   Hello World
