Quick Start

Get started developing...

# install deps
npm install

# run in development mode
npm run dev

# run tests
npm run test

Try host with local Kubernetes

All ./k8s/*.yaml files are generated with kompose that translate the ./docker-compose.yaml file into kubernetes files.

  • First you need to run and enable kubernetes from your local Docker Desktop preferences. See how https://www.docker.com/blog/how-kubernetes-works-under-the-hood-with-docker-desktop/.
  • Build express js app image 
    cp .env.example .env
docker build -t kelinci-app .
  • Apply all of our k8s pods & services file 
    kubectl apply -f ./k8s/app-deployment.yaml,./k8s/app-service.yaml,./k8s/kelinci-mq-networkpolicy.yaml,./k8s/rabbitmq-claim0-persistentvolumeclaim.yaml,./k8s/rabbitmq-claim1-persistentvolumeclaim.yaml,./k8s/rabbitmq-deployment.yaml,./k8s/rabbitmq-service.yaml
    then you'll see the output like this: 
    deployment.apps/app created
service/app created
networkpolicy.networking.k8s.io/kelinci-mq created
persistentvolumeclaim/rabbitmq-claim0 created
persistentvolumeclaim/rabbitmq-claim1 created
deployment.apps/rabbitmq created
service/rabbitmq created

Now our app already deployed on local kubernetes.

Run app with port-forward

First you can see all the running pods list using kubectl get pods then you can do port-forward it with kubectl port-forward YOUR_POD_NAME {YOUR_WANTED_PORT_TO_EXPOSE}:{APP_PORT}. For example you want to see kelinci-app and rabbitmq management hosted on port 3000 for app and 15672 for rabbitmq management dashboard, so you can run:

# assuming kelinci-app as a pod name
kubectl port-forward kelinci-app 3000:3000
# assuming rabbitmq management as a pod name
kubectl port-forward rabbitmq 15672:15672
