K3s vs rke2 Rancher its self wont directly deploy k3s or RKE2 clusters, it will run on em and import em downstream but the cloud providers 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 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。 K3S by Rancher The RKE2 Experience. 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 Air-gapped RKE2 still is not the same joy when patching for example compared to k3s. If your machines do not have unique hostnames, set the node-name parameter in the config. To read more about the config. I'm pretty sure they advertise government usage and compliance. Perfect for the Edge, IoT, and Dev Environments: K3s startup speed is a lovely distribution of Kubernetes by Rancher Labs that shines in edge computing, IoT, and development K3s/rke2 dev here. Hard to speak of “full” distribution vs K3S. S. Otherwise, k3s or vanilla k8s for on prem. You switched accounts on another tab or window. 本内容是Rancher_China RKE1、K3S、RKE2 三大 Kubernetes 发行版的比较 视频的整理与记录, 过程中有删减。. k0s. K3s provides a production-ready Kubernetes cluster from a single binary that weighs in at under 60MB. Windows Agent (Worker) Node Installation Multus and IPAM plugins. It doesn't support kine, so you have to run it on disks capable of meeting etcd's io requirements. From RKE1, it inherits close alignment with upstream Kubernetes. In a way, K3S bundles way more things than a standard vanilla kubeadm K3S on the other hand is a standalone, production ready solution suited for both dev and prod workloads. yaml file and provide a value with a valid and unique hostname for each node. However You signed in with another tab or window. Your decision should align with your project’s requirements. x version of RKE (hereafter referred to as RKE1) and K3s. Importantly, RKE2 does not rely on Docker as RKE1 K3S: K3s is developed for IoT and Edge applications. Amazon EKS Distro replaces the kubelet, kube-apiserver, etcd, CoreDNS and kube-controller-manager in RKE2 with the same binaries used K3s K3s is a lightweight, fully compliant Kubernetes distribution designed for a range of use cases, including edge computing, IoT, CI/CD, development and embedding Kubernetes into applications. Stars - the number of stars that a project has on GitHub. In places SUSE® Rancher Prime: K3s has diverged from upstream Kubernetes in order to optimize for edge deployments, but RKE1 and RKE2 can stay closely aligned with upstream. There is another big difference. RKE2 combines the best of both worlds from the 1. K3S strips out many legacy features/plugins and substitutes Kubernetes components for lightweight alternatives to achieve a binary size of ~60MB. If Anatomy of a Next Generation Kubernetes Distribution Architecture Overview . What this means is that RKE2 is, at its simplest, a single binary to be installed and configured on all RKE2 took best things from K3S and brought it back into RKE Lineup that closely follows upstream k8s. yaml file, see the Install Options documentation. RKE2: Comparing Kubernetes Distros | SUSE Communities When I joined SUSE I heard about our Kubernetes distributions: Rancher Kubernetes Engine (RKE), RKE2 and K3s. 这三个 Kubernetes 发行版都是由 Rancher 开源的，这次分享将主要 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. . It's still single-binary with a very sensible configuration mechanism, and so far it's worked quite well for me in my home lab. Multus CNI is a CNI plugin that enables attaching multiple network interfaces to pods. From K3s, it inherits the usability, Inside of a Rancher project the question came up: What are the similarities and differences between the three available products RKE, RKE2 and K3s? What are the pros and cons? If you like K3S but are you need a full kubernetes stack, consider RKE2 (aka RKE government). RKE is going to be supported for a long time w/docker compatibility layers so its not going anywhere anytime soon. Federal . RKE2 and Amazon EKS Distro both follow community standards allowing the components to easily swap in. 在 RKE2 中，我们吸取了开发和维护轻量级 Kubernetes 发行版 K3s 的经验，致力于构建一个同样具备 K3s 易用性的企业级发行版。 换言之，在最简单的情况下，RKE2 是一个二进制文件，需要在 Kubernetes 集群的所有节点上进行安装和配置。 If you're trying to run k3s in a high availability cluster (meaning 3 control planes) then you have to use etcd. 它继承了 K3s 的可用性、易操作性和部署模型。 它还继承了 RKE1 与上游 Kubernetes 的紧密结合关系。为了优化边缘部署，K3s 在某些地方与上游 Kubernetes 有所不同，但 RKE1 和 RKE2 可以与上游保持紧密一致。 重要的是，RKE2 不像 RKE1 一样依赖 Docker。 下一代 Kubernetes 发行版剖析 架构概述 . RKE2 is k3s with a more standard etcd setup and in general meant to be closer to upstream k8s. Importantly, SUSE® Rancher Prime: RKE2 does not rely The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives. Reply reply I'm not really sure about the details and differences to OpenShift, but RKE2 is hardened as well. Air-Gap Support: It can run in environments without direct internet access, offering flexibility for secure or isolated deployments. RKE2, on the other hand, excels at being robust with large applications and complex workloads. Activity is a relative number indicating how actively a project is being developed. Is K3s or RKE2 is chosen owing to a myriad of benefits? Its architecture is straightforward to set up and ideal for smaller projects or edge deployments. It's basically a better version of k3s, and more suitable for production since it uses etcd and supports HA out of the box. Because K3s is so lightweight, it’s a great option for running Kubernetes at the edge on IoT devices, low-power servers and your developer workstations. Out of the box RKE2 promised: FIPS 140–2 Compliance: Designed with a focus on security, RKE2 meets the requirements for US government projects. From K3s, it inherits the usability, ease of operation and deployment model. RKE2 is a compliant Kubernetes distribution developed by Rancher. For example, it uses sqlite instead of etcd. Before we start with the comparison, it is important to point out that at the core of K3s and K0s distro is the same upstream, open-source version of Kubernetes. Multus does not replace CNI plugins, instead it acts as a CNI plugin multiplexer. k3s and rke in tons of production clusters, each has its place. The latest RKE2 has all the modern amenities you expect, like static pods for the infrastructure, a wide selection of CNIs, and it works well with a GitOps workflow. 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. An example of K3S architecture is shown below; K3s is a fully compliant and lightweight Kubernetes distribution focused on Edge, IoT, ARM - optimized for ease of use and resource constrained environments. This is controlled by CAPI controllers and not by Rancher itself. Jest to oficjalna dystrybucja, która wpisuje się w oficjalną ścieżkę certyfikacyjną CKA – zatem sposób instalacji oraz utrzymania jest SUSE® Rancher Prime: RKE2, also known as RKE Government, is Rancher’s next-generation Kubernetes distribution. Growth - month over month growth in stars. RKE2 is just the K3s supervisor with a different execution model - static pods managed by the kubelet instead of in a single process. 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. When you make changes to your cluster configuration in RKE2, this may result in nodes reprovisioning. You signed out in another tab or window. Multus is useful in certain use cases, especially when pods are network intensive and require extra network interfaces that support dataplane acceleration techniques such as SR-IOV. Recent commits have higher weight than older ones. RKE vs. and the future rke2 I've had in the lab with shares much with k3s, it don't use docker and comes with its own containerd, you can feel the overlap in RKE2, but it was built for FIPS 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 k3s vs. Importantly, RKE2 does not rely on Docker as RKE1 K3s vs RKE2 vs Kubernetes – co wybrać? Jeśli zależy Ci by korzystać z oficjalnej dystrybucji Kubernetes dostarczanej przez CNCF – ’standardowy’ Kubernetes będzie dobrym rozwiązaniem. Reload to refresh your session. The embedded sqlite doesn't replicate between master nodes. 分享人是来自 Rancher 苏州公司的工程师，主要负责 Rancher 国内社区的运营和运维工作。 分享的主题是 "RKE1、K3S、RKE2，你 pick 哪一个？. This knowledge will then guide K3s is designed to be a lightweight and easy-to-use Kubernetes distribution, while RKE2 is a more full-featured distribution that supports more advanced RKE is a standard Kubernetes distribution without the focus on security. K3S is suggested for local or dev/test/stg installations. 这三个 Kubernetes 发行版都是由 Rancher 开源的，这次分享将主要介绍 Technical Differences RKE1 vs RKE2; Improvement in Performance and Security of RKE2; How Does RKE2 Differ from K3s? Use RKE2 vs. It also builds against goboring instead of openssl, so core bits of it are fips 140 compliant. Windows Node Support: Unlike many distributions that focus solely on Linux nodes, RKE2 RKE is used to spin up Kubernetes clusters by defining a yaml file and RKE acts on that file to create the cluster for you. Since RKE2 uses K3s as a foundation, it has its simplicity, modularity, ease-of-operations and deployment model, How is this different from RKE or K3s? RKE2 combines the best-of-both-worlds from the 1. From K3s, it inherits the usability, ease-of-operations, and deployment model. Windows Node Support: Unlike many In simple terms, K3s and RKE2 are lightweight Kubernetes distributions designed to make it easier to deploy and manage containerized applications in Kubernetes. The only differences, according to their documentation for RKE2, 但它的应用范围不仅限于政府机构，而是所有重视安全性和合规性的组织的理想选择，因此我们将其发展成了现在的 RKE2。 K3s 和 RKE2 的相似之处. K3S改进了RKE的方式，让其他主机主动去找master主机，同时服务是主机服务，权限更高。 RKE2结合了上述二者的优点，利用K3S的部署方式，同时也没有魔改K8S，部署起来又快又稳定又省事。 综上，推荐RKE2。 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 RKE2 and K3s are the better way of running Suse’s Kubernetes. Meanwhile, RKE2 is an alternative project that also See more In this article, we’ll write about what K3s and RKE2 are, their main features, and the best scenarios where you should use one over the other. I use K3S heavily in prod on my resource constricted clusters. But if you need a multi-node dev cluster I suggest Kind as it is faster. 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 new design leverages the simplified operations experience from K3s and upstream installation paradigms. K3s 和 RKE2 都由 Rancher 完全支持，都是云原生计算基金会 (CNCF) K3s is a fully compliant and lightweight Kubernetes distribution focused on Edge, IoT, ARM - optimized for ease of use and resource constrained environments. The distributions might have different release 本内容是Rancher_China RKE1 、 K3S 、 RKE2 三大 Kubernetes 发行版的比较[1] 视频的整理与记录, 过程中有删减。. K3s; K3s faster than RKE2; Working with and Troubleshooting RKE2 in Kubernetes Clusters ; completely reset an RKE2 Cluster; uninstall RKE2 from a Kubernetes Environment; Advanced RKE2 Usage: Ingress and Pod Management From K3s, it inherits the usability, ease-of-operations, and deployment model. Cloud managed clusters for cloud. We have now learned to trick RKE2 and pretend it has Internet instead of gzip or zstd archives to avoid stupid evictions of pods – node NotReady for 0-2 seconds vs 1-2 minutes Note: Each machine must have a unique hostname. It is specifically designed for security and compliance within the U. RKE2/K3s provisioning is built on top of the Cluster API (CAPI) upstream framework which often makes RKE2-provisioned clusters behave differently than RKE1-provisioned clusters. trne hxfqu nem nkal kowl ppws tggueo somcdko ytmgewz qoydlfp imop rwvf shb crzsv wkhhayin
