Apologies for the oversight. Let's include the kubectl installation command in the documentation:

This document provides detailed instructions on how to deploy the Node.js application to a Kubernetes cluster using Docker, Minikube, Argo CD, Helm charts, and GitHub Actions for CI/CD.

sudo apt update
sudo apt install docker.io -y
sudo chmod 666 /var/run/docker.sock

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
sudo install minikube-linux-amd64 /usr/local/bin/minikube && rm minikube-linux-amd64
minikube start --driver=docker

sudo apt-get update && sudo apt-get install -y apt-transport-https gnupg2 curl
curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
echo "deb https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list
sudo apt-get update
sudo apt-get install -y kubectl

kubectl create namespace argocd
kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml

curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3
chmod 700 get_helm.sh
./get_helm.sh

1. Configure GitHub Actions workflows in your GitHub repository to automate the Docker image build and push process upon changes.

2. Make sure to add DockerHub credentials securely to GitHub repository secrets for access during CI/CD workflows.

1. Create a new GitHub repository in your account.

2. Push the following files to your GitHub repository:

   • Node.js application code.
   • Dockerfile.
   • Helm chart for the application.
   • Argo CD YAML files for application deployment.

Ensure the Docker image for the Node.js application is available on DockerHub. Your DockerHub repository URL is: Your DockerHub Repository URL.

To access your DockerHub repository URL using kubectl, run the following command:

kubectl port-forward svc/helmrelease-nodeapp --address 0.0.0.0 3000:3000

1. Provide Argo CD with necessary details:

   • Git repository URL.
   • Path to values.yaml file.
   • Path to Helm chart directory.

2. Argo CD will automatically deploy the application to the Kubernetes cluster upon changes to the Helm chart or application code triggered by GitHub Actions.

1. Access the deployed Node.js application:

   kubectl port-forward svc/helmrelease-nodeapp --address 0.0.0.0 3000:3000

   The application will be accessible at http://localhost:3000.

2. Access the Argo CD dashboard:

   kubectl port-forward svc/argocd-server -n argocd --address 0.0.0.0 8080:443

   The Argo CD dashboard will be accessible at https://localhost:8080.

Congratulations! You have successfully deployed the Node.js application to Kubernetes using Docker, Minikube, Argo CD, Helm charts, and GitHub Actions. Continuous integration and continuous deployment (CI/CD) pipelines ensure efficient development workflows and maintain the desired state of your application.
