Minikube Node App Deployment Boilerplate

This guide will help you set up and deploy a Node.js application on Kubernetes using Minikube. The instructions below cover both Windows and macOS environments.

Requirements

• Docker
• kubectl
• Minikube

Docker Setup

macOS

1. Download and install Docker Desktop for Mac from the official Docker website.
2. Once installed, start Docker Desktop from your Applications folder.

Windows

1. Download and install Docker Desktop for Windows from the official Docker website.
2. After installation, start Docker Desktop from the Start Menu.

Kubectl Setup

macOS

1. Install kubectl using Homebrew:

   brew install kubectl

Windows

1. First, install Chocolatey if you haven't already.
2. Open an administrative command prompt and run:

   choco install kubernetes-cli

Minikube Setup

macOS

1. Install Minikube using Homebrew:

   brew install minikube

2. Start Minikube:

   minikube start

Windows

1. Install Minikube using Chocolatey:

   choco install minikube

2. Start Minikube:

   minikube start

Build the Docker Image

macOS

1. Run the following command in the source folder to configure Docker to use Minikube's Docker daemon:

   eval $(minikube docker-env)

2. Build the Docker image:

   docker build -t basicnodeapp .

Windows

1. Open PowerShell and run the following command in the source folder to configure Docker to use Minikube's Docker daemon:

   minikube docker-env | Invoke-Expression

2. Build the Docker image:

   docker build -t basicnodeapp .

Deploy the App to Kubernetes

macOS & Windows

1. Apply the deployment configuration:

   kubectl apply -f deployment.yaml

2. Apply the service configuration:

   kubectl apply -f service.yaml

Access the App through Minikube

macOS & Windows

1. Open the Node.js application in your browser:

   minikube service basicnodeapp-service

This command will launch your default browser and navigate to the Node.js app running on Minikube.
