k3s

This project contains a set of scripts to set up a k3s cluster with NGINX Ingress Controller, Kubernetes Dashboard, and ArgoCD.

Scripts

• 01-start-k3s.sh: Installs k3s.
  • Pass dev as an argument to run in development mode (e.g., ./01-start-k3s.sh dev).
  • In development mode, --tls-san and --kubelet-arg are not used.
  • The script will not overwrite an existing kubeconfig file. If one is found, it will alert the user.
• 02-deploy-nginx-ingress.sh: Deploys the NGINX Ingress Controller using Helm and installs cert-manager.
  • If Helm is not installed, the script will install it automatically.
• 03-setup-dashboard.sh: Installs the Kubernetes Dashboard using Helm and creates a service account for dashboard access.
• 04-start-dashboard.sh: Starts the Kubernetes Dashboard using kubectl port-forward.
• 05-get-dashboard-token.sh: Gets the token for the 'admin' service account.
• 06-install-argocd.sh: Installs ArgoCD.
• 08-get-argocd-password.sh: Gets the initial admin password for ArgoCD.
• 09-start-argocd-dashboard.sh: Starts the ArgoCD dashboard using kubectl port-forward.

Usage

The scripts should be executed in the following order:

1. ./01-start-k3s.sh (or ./01-start-k3s.sh dev for development)
2. ./02-deploy-nginx-ingress.sh
3. ./03-setup-dashboard.sh
4. ./04-start-dashboard.sh
5. ./05-get-dashboard-token.sh
6. ./06-install-argocd.sh
7. ./08-get-argocd-password.sh
8. ./09-start-argocd-dashboard.sh

After running these scripts, you will have a fully functional k3s cluster with a Kubernetes Dashboard and ArgoCD.
