Features & Specs

  1. Lightweight

    K3s is designed to be lightweight and less resource-intensive compared to full Kubernetes distributions, making it ideal for edge and IoT devices, as well as development environments.

  2. Easy Installation

    K3s provides a simple installation process, requiring only a single binary for installation, which simplifies the setup procedure for users.

  3. Low Resource Usage

    By stripping away non-essential features, K3s consumes significantly fewer resources, lowering the barrier to entry for running Kubernetes on resource-constrained environments.

  4. Fully CNCF Conformant

    K3s is certified by the Cloud Native Computing Foundation (CNCF) as conformant with standard Kubernetes, meaning it follows the same API and operational model.

  5. Built-In Database

    K3s includes an embedded SQLite database by default, which simplifies deployment and reduces the complexity associated with managing an external etcd cluster.

  6. Automated TLS Management

    K3s has integrated support for TLS certificates management, which helps in ensuring secure communications between components without additional configuration.

  7. Ecosystem Compatibility

    K3s supports popular Kubernetes add-ons and CI/CD tools, so it can be seamlessly integrated into existing Kubernetes-based workflows.

  • Scaling Spin Apps With KEDA
    Setting up the Kubernetes cluster and the AWS SQS queue is outside the scope of this article, but you can deploy an Amazon EKS cluster by following this guide, or use k3s as a lightweight, local alternative. For setting up an SQS queue, refer to this tutorial. - Source: dev.to / 4 months ago
  • My 2024 review
    Start with small-scale experiments using k3s/k3d. - Source: dev.to / 5 months ago
  • Using SpinKube on Kairos
    This will initialize K3S (a lightweight Kubernetes distribution), and will configure the Kairos SpinKube bundle we will install in a moment. - Source: dev.to / 5 months ago
  • A Very Deep Dive Into Docker Builds
    Finally the main reason for us is the choice of runtime. We have very decent container runtimes (RKE, RHOS, K3s) available to deploy applications. We are very familiar with them, and they offer us a lot of functionality. These all support containers primarily. - Source: dev.to / 5 months ago
  • Building a Kubernetes Cluster from Scratch With K3s And MetalLB
    I used K3S in my cluster because it is a lightweight, stripped-down version of Kubernetes that’s ideal for running on resource-constrained devices like Raspberry PIs I plan to use in my home lab cluster. K3S can be installed through a shell script:. - Source: dev.to / 6 months ago
  • Lightweight Kubernetes and Wasm is a Perfect Combo
    In the last few years, we’ve witnessed the introduction of several new lightweight Kubernetes distributions. SUSE’s Rancher Labs k3s project was one of the earliest. Canonical now includes Microk8s in Ubuntu. And k0s is a single-binary Kubernetes distribution. - Source: dev.to / 6 months ago
  • Create your K3S lab on Google Cloud
    K3S is a Kubernetes distribution made by Rancher, made to be as lightweight as possible while being compatible with Kubernetes production standards. - Source: dev.to / 7 months ago
  • Turing Pi 2 Home cluster
    Jeff led me to K3s using Ansible, a lightweight Kubernetes distribution that is perfect for my home cluster and a pre-defined way of installing it because I don't have pre-requirements nor the idea on how to set it up otherwise. - Source: dev.to / 7 months ago
  • I Solve Problems (talk at EuroBSDCon 2024)
    Still requires SRE but alot easier than it used to be: https://www.talos.dev/v1.8/ Also, k3s. https://k3s.io/. - Source: Hacker News / 7 months ago
  • Docker Desktop Alternative
    I'm torn between https://k0sproject.io and https://k3s.io to use in CI and production. Any suggestions or personal experience? - Source: Hacker News / 7 months ago
  • Does Your Startup Need Complex Cloud Infrastructure?
    What you also can do is starting with just a single node, incredibly easy to install with e.g. https://k3s.io/. You still have to invest the upfront effort to understand how it works but you can already reap a lot of benefits with a lot less complexity. Kubernetes does not force you into the distributed systems hell, you can go that route later, or never. - Source: Hacker News / 8 months ago
  • Reclaim the Stack
    > Gosh, I'm so happy I was able to jump of the k8s hype train. This is not something SMBs should be using. Now I happily manage my fleet of services without large infra overhead via my own paas over Docker Swarm. :) I mean, I also use Docker Swarm and it's pretty good, especially with Portainer. To me, the logical order of tools goes with scale a bit like this: Docker Compose --> Docker Swarm --> Hashicorp Nomad /... - Source: Hacker News / 8 months ago
  • How I learned to stop worrying and love userspace networking
    The author is using https://k3s.io/ not the full k8s, so it doesn't have to be extremely expensive. - Source: Hacker News / 8 months ago
  • Let's Make a k3s Cluster with Raspberry Pi and Cloudflare Tunnel
    For those who don't know k3s, it's a light weight version of Kubernetes suitable for IoT & Edge devices. One of the advantages of k3s is it's easier to install and make it up and running. - Source: dev.to / 9 months ago

  • 26 Top Kubernetes Tools
    K3s is another compact Kubernetes distribution. Developed by SUSE, it's packaged as a single binary that comes in at less than 70MB. Despite this tiny footprint, K3s is certified as compatible with upstream Kubernetes, is ready for production use, and supports high availability. - Source: dev.to / 11 months ago
  • Linux fu: getting started with systemd
    For self-hosting I've found https://k3s.io to be really good from the SUSE people. Works on basically any Linux distro and makes self-hosting k8s not miserable. - Source: Hacker News / about 1 year ago

  • K3s Traefik Ingress - configured for your homelab!
    I recently purchased a used Lenovo M900 Think Centre (i7 with 32GB RAM) from eBay to expand my mini-homelab, which was just a single Synology DS218+ plugged into my ISP's router (yuck!). Since I've been spending a big chunk of time at work playing around with Kubernetes, I figured that I'd put my skills to the test and run a k3s node on the new server. While I was familiar with k3s before starting this project,... - Source: dev.to / over 1 year ago
  • Building a no-code Helm UI with Windmill - Part 1
    I’ve created a local cluster with K3S and installing Windmill could not be simpler with just one chart to configure, which already has sane defaults to get started. For this demo we will also configure workers to passthrough environment variables to our scripts so that they have access to the Kubernetes API server for later. - Source: dev.to / over 1 year ago
  • Highly scalable Minecraft cluster
    You should be familiar with Kubernetes and have set up a Kubernetes cluster. I recommend k3s. - Source: dev.to / over 1 year ago
