"RancherOS v2 is an immutable Linux distribution built to run Rancher and it's corresponding Kubernetes distributions RKE2 and k3s. KubeVIP is a k8s LB that runs as a daemonset in k8s on the same hardware and provide HA for the control plane and worker nodes / applications. Initial node configurations is done using a cloud-init style approach and all further maintenance is done using Kubernetes operators. And RKE2 is pretty much k3s with different defaults. Jul 30, 2020 · RKE2 uses upstream Kubernetes and associated runtime and, uses embedded etcd for it's data store. Jul 21, 2023 · RKE2 is very similar to k3s. K3s: The Good and The Bad. 11 with calico rancher installed (but shouldn't matter) Anatomy of a Next Generation Kubernetes Distribution Architecture Overview . RKE, I won’t explain each function in-depth, but here is a summary of the primary features: Create, upgrade, and manage Kubernetes clusters. Do most companies use managed kubernetes services (EKS,AKS,GKE) or self managed kubernetes (VM's on the cloud)? Kind, minikube, microk8s, and k3s are all things I’ve seen used locally to get all the kinks worked out before using some of the other tools I’ve seen mentioned tokens in this thread like ArgoCD to handle deployments to other environments. Homelab: k3s. The design decisions are there because it will be the next generation of K8s distro for rancher, it isn't a distro for the "people" it is a K8s for the any of these will work for you. K3s use the standard upstream K8s, I don't see your point. maintain and role new versions, also helm and k8s I really like RKE2 but for the deployment I'm working on it's preferable to use nodes for both compute and nvme storage cluster to reduce weight. See full list on suse. It also builds against goboring instead of openssl, so core bits of it are fips 140 compliant. It's basically a better version of k3s, and more suitable for production since it uses etcd and supports HA out of the box. I run a number of RKE, RKE2, and k3s clusters using this provider for both NFS and iSCSI storage both in the lab and in production environments. k3s. Fully moved on from the manual k3s install / vm management side of things straight into gitops using rke2 since this now handles it all for me (skipped over hardware / vm orchestration tech since I didn't care). RKE2 is barely more than GKE/EKS give you. I dont have to build from scratch via kubeadm, i dont have to install networking, adding to a cluster is a literal 1 line copy+paste. There's not much that you can do with RKE2 that you couldn't do with k3s. If you want something more serious and closer to prod: Vagrant on VirtualBox + K3S. Yes, RKE2 isn't lightweight, but the 'kernel' of it is K3s. 24 Then installed longhorn, kube-prometheus and cert-manager and setup traefik properly to have a redirect from http to https. Remember that K3s is a lightweight distribution for resource-constrained environments and designed to ease the operation, since in edge scenarios we can manage thousands or hundreds of Rancher its self wont directly deploy k3s or RKE2 clusters, it will run on em and import em downstream but the cloud providers deploy RKE clusters right now. com Aug 8, 2024 · When starting the k3s or rke2 service on a node, the k3s is much faster to start up.
