This guide demonstrates how to create nginx container in K3s Kubernetes distribution with valid Let's Encrypt certificate for HTTPS. Let's Encrypt certificate will be obtained using DNS challenge method with a domain registered on Cloudflare.
OS used: Debian 12
Software used: K3s 1.30.5, Helm 3.16.2, cert-manager 1.16.1
K3s is a lighter variant of Kubernetes distribution than RKE2, which was discussed in previous posts. It is well-suited for single node homelab environments or IoT deployments where resource efficiency is important. Based on my testing, K3s consumed less CPU in an idle state than RKE2. In this blog post I will show how to install K3s.
OS used: Debian 12
Software used: K3s 1.30.5
Following RKE2 Kubernetes distribution installation instructions in the last post, here I will show how to run simple nginx container.
OS used: Debian 12
Software used: RKE2 1.30.2, Helm 3.16.2, cert-manager 1.16.1
In homelab environment it's nice to have a host which can run containerized apps. For running containers on such host you can use Docker, Podman or Kubernetes. In this post I will show how to install RKE2 Kubernetes distribution.
OS used: Debian 12
Software used: RKE2 1.30.10
