A significant advantage of k3s vs. It is the most recent project from Rancher Labs and is designed to provide an alternative to k3s. A flatter learning curve – There are fewer components to learn before applying it to real-world situations. Both K3s and MicroK8s exhibit different capabilities in this area, as detailed below. can do that stuff but with Edit: I think there is no obvious reason to why one must avoid using Microk8s in production. MicroK8s vs K3s vs minikube. To download and run the command, type: Install K3s with a single command: curl -sfL https://get. Minikube, K3s, and MicroK8s all provide an easy way of running lightweight Kubernetes. Installing k3s. Analyzing various Kubernetes versions, the handling of extensions and add-ons becomes a pivotal consideration. Or check it out in the app stores Small Kubernetes for your local experiments: k0s, MicroK8s, kind, k3s, and Minikube blog. So, if you want a fault tolerant HA control plane, you want to configure k3s to use an external sql backend oretcd. Still working on dynamic nodepools and managed NFS. Please check out the documentation for more info or It's a 100% open source Kubernetes Dashboard and recently it released features like Kubernetes Resource Browser, Cluster Management, etc to easily manage your applications and cluster across multiple clouds/ on-prem clusters like k3s, microk8s, etc. K3s also does great at scale. I know k8s For performance-constraint environments, K3S is easy to use the lightweight Kubernetes implementation. Was put off microk8s since the site insists on snap for installation. We chose cilium a few years ago because we wanted to run in direct-routing mode to avoid NAT‘ing and the overhead introduced by it. what to used in prod microk8s, kubeadm, k3s, minikube and any others kubernetes supported tools? comments sorted by Best Top New Controversial Q&A Add a Comment. Yes, it is possible to cluster the raspberry py, I remember one demo in which one guy at rancher labs create a hybrid cluster using k3s nodes running on Linux VMs and physical raspberry py. I don't think there's an easy way to run Kubernetes on Mac without VMs. The last My company originally explored IoT solutions from both Google and AWS for our software however, I recently read that both MicroK8s and K3s are potential candidates for IoT fleets. UPDATE Step 1: Discover k3s. (edit: I've been a bonehead and misunderstood waht you said) From what I've heard, k3s is lighter than microk8s. Whilst MicroK8s installed, i was unable to run ANY MicroKs8s commands. I could never scale a single microk8s to the meet the number of deploys we have running in prod and dev. Hi, I've been using single node K3S setup in production (very small web apps) for a while now, and all working great. The API is the same and I've had no problem interfacing with it via standard kubectl. Internet Culture (Viral) Additionally it's cloud and cluster agnostic which allows you to deploy on as small as k3s, microk8s cluster and also on managed clusters like EKS. If you switch k3s to etcd, the actual “lightweight”ness largely evaporates. Develop IoT apps for k8s and deploy them to MicroK8s on your Linux boxes. MicroK8S offers more features in terms of usage but it is more difficult to configure and Unveiling the Kubernetes Distros Side by Side: K0s, K3s, microk8s, and Minikube ⚔️ I took this self-imposed challenge to compare the installation process of these distros, and I'm excited to share the results with you. I had to use a fork to get k3s v1. Raspberry pi’s are pretty easy and cheap to setup. K3s is just a lightweight K8s distribution whereas KubeEdge is a K8s-based framework that tries to bring K8s functionalities to the edge, taking into consideration the specific characteristics of Edge Computing (limited computing capabilities, network instability Community Comparison. but still very close to k3s which is supposed to be used for production in small systems Microk8s vs k3s: What is the difference? Microk8s is a low-ops production Kubernetes. It consumes the same amount of resources because, like it is said in the article, k3s is k8s packaged differently. Ultimately, the choice between Minikube, Kind, and K3s hinges on specific project requirements, resource availability, and preferred workflows. Show all references. It is easy to install and requires minimal configuration. . I contacted Canonical to ask their advice about the above, and was told that by default, MicroK8s installs the Calico network driver and uses dqlite rather then etcd, which is not needed for single-node deployments. Docker still uses a VM behind the scenes but it's anyway lightweight. K3s has builtin support for an etcd dataplane that you don't have to manage yourself. Depends on how much you wanna do with it. There are many different options out there, but a few select reign over the others as the most common, including minikube, kind, K3s, kubeadm, Docker Desktop, and MicroK8s. What you learn on k3s will be helpful in any Kubernetes environment. Kubernetes Configuration: Microk8s vs K3s. I plan to use Rancher and K3s because I don't need high availability. Other than that, they should both be API-compatible with full k8s, so both should be equivalent for beginners. K3s: K3s is a lightweight Kubernetes distribution that is specifically designed to run on resource-constrained devices like the Raspberry Pi. Let’s take a look at Microk8s vs k3s and discover the main differences between these two options, focusing on various aspects like memory usage, high availability, and k3s and microk8s compatibility. For example, in a raspberry py, you wouldn't run k3s on top of docker, you simply run k3s directly. Using k3s at home to learn is great and you won't really be missing out on much, it's just worth learning what k3s actually is and the different ways to run Kubernetes.

More details here. Conclusion: Choosing the Right Tool for Your Project. You could spin up a HA k3s cluster alongside the existing single node microk8s "cluster" and use something like velero to migrate any PVs. Along the way we ditched kube-proxy, implemented BGP via metalLB, moved to a fully eBPF based implementation of the CNI with the last iteration and lately also ditched metalLB (and it‘s kube-router based setup) in favour of cilium-powered We're using microk8s but did also consider k3s. com Open. Comparison table. My preference would have been for OS Parity but in reality bar a few edge cases it doesn't matter. In general, you're likely to find K3s deployed more often for testing purposes on local devices, whereas MicroK8s is a better fit for deploying I'm trying to setup Kubernetes on my home server (s).

For testing in dev/SQA and release to production we use full k8s. I think manually managed kubernetes vs Microk8s is like Tensorflow vs PyTorch (this is not a direct comparison, because tensorflow and PyTorch have different internals). K3s has a similar issue - the built-in etcd support is purely experimental. I am running a Microk8s, Raspberry Pi cluster on Ubuntu 64bit and have run into the SQLite/DBLite writing to NFS issue while deploying Sonarr. There're many mini K8S products suitable for local deployment, such as minikube, k3s, k3d, microk8s, etc. So, looking solely at local use, especially for devs working with macbooks, I believe k3s/d is a great choice I use k3s whenever I have a single box, vanilla kubeadm or k3s join when I have multiples, but otherwise I just use the managed cloud stuff and all their quirks and special handling. I have a Pi cluster using Flux2 and a gitops repo for all of my helmrelease files. MicroK8s is great for offline development, prototyping, Before explaining how Minikube, K3s, and MicroK8s are different, let's discuss what makes them similar: They are all lightweight Kubernetes distributions. there’s a more lightweight solution out there: K3s It is not more lightweight.
