🔐 TLS Certificates for Homelab Using Cloudflare + Cert-Manager + Let’s Encrypt With Traefik operational as the ingress controller in a K3s cluster, the next logical step is to provision HTTPS automatically using Let’s Encrypt certificates, Cloudflare DNS validation, and Cert-Manager. This ensures encrypted traffic across services in a self-hosted homelab. ☁️ Prerequisites A domain managed by Cloudflare An API token with DNS edit permissions Traefik installed and configured as the ingress controller A functional K3s cluster with outbound internet access 🔧 Step 1: Install Cert-Manager Install cert-manager using Helm ...

🚀 Self-Hosting with K3s and Traefik Set up a lightweight Kubernetes cluster using K3s on a Raspberry Pi, deploy Traefik via Helm, and prepare for self-hosted services with ingress routing and local TLS. 🧰 Prerequisites A Linux host with root access (e.g., Raspberry Pi or any ARM64/x86_64 board) kubectl installed on a client machine Helm 3 installed on the cluster (https://helm.sh/docs/intro/install/) ⚙️ Install K3s without Traefik Skip the bundled Traefik and gain full control by managing ingress via Helm ...
