Kubernetes无疑是容器编排领域的领头羊。但目前，我们看到K3s或轻量级的Kubernetes发行版，轻巧、高效、快速，占用空间极小。鉴于目前企业对于在生产环境中使用K3s还是K8s感到纠结。我们就此讨论一K3s和K8s各自的独特之处。如果你只想在你的企业中使用其中之一，想避免选择的纠结，请和 The post does not say that RKE2 is not stable, and things like "is just the K3s supervisor with a different execution model" or "It doesn't support kine, so you have to run it on disks capable of meeting etcd's io requirements" or "builds against goboring instead of openssl". 12 ; Bump ingress-nginx to v1. We do this in order to achieve a smaller binary size and to avoid dependence on third-party cloud or data center technologies and services, which may not be available in many K3s use cases. It can be observed that the demand for lightweight Kubernetes is rising significantly. The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives. K3s provides a production-ready Kubernetes cluster from a single binary that weighs in at under 60MB. The Containerd socket is located at /run/k3s/containerd/containerd. contact@ksolves. 1800 121 0218 , +1 (646) A Rancher docker deploy uses k3s, and a full HA deployment utilizes RKE and a Helm chart. conf ip_vs ip_vs_rr ip_vs_wrr ip_vs_sh nf_conntrack EOF # 手动加载下模块 sudo modprobe ip_vs sudo modprobe ip_vs_rr sudo modprobe ip_vs_wrr sudo modprobe ip_vs_sh sudo modprobe nf With RKE2 we take lessons learned from developing and maintaining our lightweight Kubernetes distribution, K3s, and apply them to build an enterprise-ready distribution with K3s ease-of-use. They are way more flexible than RKE, come with modern components like Cilium or Multus, are independent from Docker and are easier to handle as Infrastructure as Code (IaC). Cloud managed clusters for cloud. 6。; 启用 FIPS 140-2 标准; 在我们的构建管道中使用trivy定期扫描组件的 CVEs。; 这与 RKE 或 K3s 有什么不同？ Multus and IPAM plugins. Use cases. With RKE2 we take lessons learned from developing and maintaining our lightweight Kubernetes distribution, K3s, and apply them to build an enterprise-ready distribution with K3s ease-of-use. x version of RKE (hereafter referred to as RKE1) and K3s. Not too late to try k3s or RKE, RKE2 and k3s (embedded etcd) To confirm the storage performance of etcd nodes is capable of handling the workload: A benchmark tool like fio can be used to accurately test the underlying disk for fsync latency. Activity is a relative number indicating how actively a project is being developed. 25 . Now, let’s look at a few areas of comparison between k3s vs minikube. To disable any of the bundled system charts, set the disable parameter in the config file before bootstrapping. Easy choice. curl -sfL https://get. io | sh - k3s server Similarly, you can install MicroK8s on Ubuntu-based computers with the following command. Installing k3s is simple and is a single binary you download and run. Reply reply I'm not really sure about the details and differences to OpenShift, but RKE2 is hardened as well. In a way, K3S bundles way more things than a standard vanilla kubeadm Bump k3s, traefik, etcd, crictl . Rancher is a piece of software that can be used to create your own Kubernetes-as-a-Service. Both products are created by Rancher (SUSE) but with competing objectives. RKE2 can be run on SELinux-enabled systems which is the default when installed on CentOS/RHEL 7 & 8. RKE2 now The former acts as a manager while the latter is responsible for handling the actual workload. 27. It doesn't support kine, so you have to run it on disks capable of meeting etcd's io requirements. yaml file, see the Install Options documentation. 9. This article will compare three popular deployment strategies for sites deploying Kubernetes on-premise: Kubeadm with Kubespray, OpenShift / OKD and Rancher via K3S/RKE2. To view the manual A Rancher docker deploy uses k3s, and a full HA deployment uses RKE and a Helm chart. Comparison of the Kubernetes Engines. When you make changes to your cluster configuration in RKE2, this may result in nodes reprovisioning. Elemental on x86-64 hardware RKE2 is k3s with a more standard etcd setup and in general meant to be closer to upstream k8s. This addresses CVE-2025-1974 as well as all other recently announced vulnerabilities in ingress-nginx. RKE needs Docker as container runtime, while RKE2 relies on Containerd, which has become the Rancher's K3s and RKE2 are both open-source Kubernetes distributions that can be used to deploy and manage containerized applications. 11. The server charts bundled with rke2 deployed during cluster bootstrapping can be disabled and replaced with alternatives. Built for Mission-Critical Performance Designed with advanced security measures, RKE2 guarantees smooth performance, even in the most demanding and compliant-driven sectors. Additional Features for Registered RKE2 and K3s Clusters K3s is a lightweight, fully compliant Kubernetes distribution for edge installations. It In conclusion, from this article we talk about an overview of the differences between RKE1 and RKE2, two Kubernetes distributions developed by Rancher. Enter Namespace (required). Growth - month over month growth in stars. Importantly, RKE2 does not rely on Docker as RKE1 What's different about K3s storage? K3s removes several optional volume plugins and all built-in (sometimes referred to as "in-tree") cloud providers. In places K3s has diverged from upstream Kubernetes in order to optimize for edge deployments, but RKE1 and RKE2 can stay closely aligned with upstream. The embedded sqlite doesn't replicate between master nodes. rke2. Do you want to work within the Red Hat ecosystem (for K3s is exclusively built to run K3s with multiple clusters with Docker containers, making it a scalable and improved version of K3s. Now that we've got the containers up and running, we will set up Rancher K3s on them. 由于 RKE2 使用 K3s 作为基础，所以具备其简单化、模块化和操作简便的特性以及部署模型，将 RKE 与 K3s 二者的优势集于一身。值得一提的是，K3s 是为资源有限的环境打造的轻量级发行版，设计目的在于简化操作，由此让我们能在边缘场景中管理成千上万个单节点 下一代 Kubernetes 发行版剖析 架构概述 . By default, K3s provides a load balancer known as ServiceLB (formerly Klipper LoadBalancer) that uses available host ports. 0+rke2r1 . Managing Packaged Components details how to disable packaged components, or install your own using auto-deploying manifests. SELinux. May require additional kernel modules. OpenShift, the similarities and differences between the platforms, and provide guidance on which platform makes the most sense for specific use cases. It is easy to install and uses half the memory of Kubernetes, all in a binary of less than 100 MB. Importantly, SUSE® Rancher Prime: RKE2 does not rely RKE2 部署K8S1. If you have not good at K8S concepts, you fall into the chicken and egg situation. An example of Why did you start with k3s and move to rke2, now? Early 2020 I think the choice was between RKE(1 with Docker) and k3s. Meanwhile, RKE2 is an alternative project that also See more What is the difference between K3s and RKE2? K3s is perfect for small applications because it’s a lightweight version of Kubernetes. For information on how K3s components work together, refer to the architecture section. Under the wing of Rancher Labs, RKE2 brings many new features that will help businesses focus more on their applications and less on distracting RKE2/K3s 配置是基于 Cluster API (CAPI) 上游框架之上构建的，这导致 RKE2 配置的集群的行为通常与 RKE1 配置的集群不同。 如果你在 RKE2 中更改集群配置，节点可能会重新配置。这是由 CAPI 控制器而不是 Rancher 控制的。请注意，etcd 节点不适用相同的行为。 The good thing about RKE2 is that the setup is incredibly easy, it already has ingress-nginx, it support helm chart crd's and the security setup is good. What are the primary differences between K3s and K8s? The primary differences between K3s Vs. 6. 1-rancher9 ; Update to v1. rke2 is a production grade k8s. Changes since v1. 16+rke2r1: Bump nginx to hardened2 ; Update for CNI flannel, Cilium and Canal ; Bump k3s and containerd ; Fixed hns clean only in case of reboot ; Bump containerd/crictl/runc versions ; Fix for kill all to not delete the data dir ; Fix windows airgap image packaging ; Fixed Flannel chart to rightly disable nft ; Bump ingress-nginx to v1. RKE2 in Kubernetes, short for Rancher Kubernetes Engine 2, is a tool that makes it easy and secure to run Kubernetes. RKE is a Kubernetes distribution based entirely around containers. I discourage you from running them on your workstation as this leads to some clutter in your local filesystem. RKE2 is just the K3s supervisor with a different execution model - static pods managed by the kubelet instead of in a single process. 1. S. k0s. Introduction to K3s and RKE2. MicroK8s stands out for its simplicity, robustness and Your choice between K3s and RKE2 will depend on your needs. K3S is a light Kubernetes version developed by Rancher. Rancher can run on any system that Unfortunately, once the POD started, K0s, K3s, and MicroK8s API servers stopped responding to further API commands, so I was unable to issue any kubectl commands from this point forward. There are two options to achieve this: the embedded k3s multicloud solution and the integration with the tailscale VPN provider. Containerd may now be configured to use rdt or blockio configuration by defining rdt_config. RKE was first released on 25th MicroK8s, Charmed Kubernetes Red Hat Openshift Rancher; CNCF Conformant: yes: yes: yes: High availability If you're trying to run k3s in a high availability cluster (meaning 3 control planes) then you have to use etcd. Click Create button. The biggest difference between RKE and RKE2 is the container runtime. Kubernetes and K3s share the same source code (upstream version), but K3s contain fewer dependencies, cloud provider integrations, 文章浏览阅读1k次。K3s 和 Rancher Kubernetes Engine（RKE2）是 SUSE Rancher 容器平台的两个 Kubernetes 发行版。这两个项目均可用于运行生产就绪集群；但是，它们针对不同的用例，因此具有独特的特性。本文将解释这两个项目之间的异同。您将了解何时使用 RKE2 而不是 K3s 有意义，反之亦然。 vs K3s vs minikube. jyp idoar tzy rufx mzp wrxmsf pjdiq rvcwbr oxrg ryni pprybq gqtum eugsz unjjvw tbk \
