Deployment

For a real application, the deployment phase would involve a CI/CD job to build and publish the image to a container repository. Also, the manifests in kubernetes-manifests directory would need to include some manifests for networking (Service, OpenShift Route, service mesh, etc.). Then, you could deploy the manifests in the kubernetes-manifests directory.

For this sample application, you can run it on Docker Desktop. Instructions for just Docker and the Docker Desktop Kubernetes are provided below.

Setting up Docker Desktop

1. First, download Docker Desktop if you don't have it from this link
2. Ensure the docker command works.
3. Run the following commands:

docker build . -t fibonacci-java-sample

docker run -it -p 8080:8080 -e "FIBONACCI_SETTING=bigint-forloop" fibonacci-java-sample

4. Make requests to localhost:8080/fibonacci?sequenceNumber={yourNumber}, or head to localhost:8080/quick-test.html to access the test webpage.

Running with Docker Desktop Kubernetes

1. First, download Docker Desktop if you don't have it from this link
2. Run the Docker Desktop application
3. Enable Kubernetes

4. Ensure the docker and kubectl commands work.
5. Run the following commands:

docker build . -t fibonacci-java-sample

kubectl apply -f kubernetes-manifests

6. This directory does not currently include any networking, but you can test with kubectl port-forward:

kubectl get pod
kubectl port-forward <pod id> 8080
curl localhost:8080/fibonacci\?sequenceNumber=1000
