1. Install pulumi

   brew install pulumi/tap/pulumi
   

2. Install nodejs

   brew install node
   

3. Install kubernetes cluster using docker desktop

   This should create an entry in your /etc/hosts as below

   # Added by Docker Desktop
   # To allow the same kube context to work on the host and the container:
   127.0.0.1 kubernetes.docker.internal
   # End of section
   

4. Create a folder and unzip the code.

   mkdir pulumi && cd pulumi
   unzip pulumi-hello-world
   cd pulumi-hello-world
   

5. Deploy the app into k8s cluster using the following command

    pulumi up --logtostderr

You should see something similar on your console as shown below when app gets deployed in k8s cluster.

     Type                              Name                     Status

Copy the following URL into your browser

http://kubernetes.docker.internal/hello

You should be able to see similar output.

Hello from the Kubernetes worker node with IP address: 192.168.65.4

This repository contains a nodejs application under app directory. It hosts the endpoint /hello, which returns a pre-configured message and IP address of the node where the application pod is running.

• To build node js application docker container run the following command.

  docker build . -t node-hello-world
  

• Tag the image

  docker tag node-hello-world:latest <your-repo>/node-hello-world:latest
  

• Push the docker image into a docker repository

  docker push <your-repo>/node-hello-world:latest
