K8s-HELM-ARGO-DEMO

This repo consists of scripts to spin up a self-contained single node cluster with k3s, Helm, ArgoCD and nginx as a demo service. It also has a script to teardown the whole setup.

The scripts are grouped into CPU architecure.

Apple Silicon ARM_x64 (M1+)

  • install UTM app https://mac.getutm.app/. I wasn't able to get VMWare Fusion, VirtualBox, Ubuntu Multipass virtualisation software working on Apple M1 Pro/M2 at all, UTM was the saviour.
  • Use Ubuntu 22.04
  • SSH into the VM and run the setup

Quick TLS setup using self-signed certificate

  • Assuming the openssl is installed, run the following commands to generate a private key and self-signed certificate (valid for 365 days).

    openssl genrsa -out demo-svc.key 4096
openssl req -x509 -new -nodes -days 365 -key demo-svc.key -out demo-svc.crt -subj="/CN=your domain or IP address"

    The browsers will warn you for usign this self-signed cert. But this is the start.

  • Add K8s secret using this key and the cert. kubectl create secret demo-tls-secret --key demo-svc.key --cert demo-svc.crt

  • Look at the created secret kubectl describe secrets/demo-tls-secret

  • Take a look at the service ports in your cluster using kubectl get service -A or by name. You will see something like nginx nginx-app NodePort 10.43.26.102 <none> 80:31818/TCP,443:30890/TCP 26d. 30890 is the port that you should use from your client/host machine.
