akka-java-cluster-openshift

This is based on Hugh's Akka Cluster demo app with the nice visualizer. We've only removed a few config options so they go back to defaults, and updated Akka Mangement to 1.0, and then specify the app with an AkkaCluster resource instead of Namespace + Role + Rolebinding against default account + Deployment.

The AkkaCluster resource can be installed in any namespace.

install the AkkaCluster operator

To install the operator, clone this repo and follow README. It is pre-built so you're just loading Kubernetes resources in this step and using the bintray image.

https://github.com/lightbend/akka-cluster-operator

build the app docker image (optional)

mvn clean package docker:build

If this doesn't work, you can git checkout bintray and go straight to the deploy step, using a pre-built image published to bintray.

openshift

git checkout bintray
kubectl apply -f ./kubernetes

make a Route to deployment/akka-cluster-demo port 8080 for the UI

minikube

Install the AkkaCluster Operator.

Build the app against minikube's docker environment. Verify that the akka-cluster-demo:1.0.2 image is in minikube's registry:

docker images

Deploy the app:

kubectl apply -f ./kubernetes

Expose the built in UI:

kubectl expose deployment/akka-cluster-demo --type=NodePort --port 8080

Go to the UI:

minikube service akka-cluster-demo
