Understanding the scenarios where each tool excels can significantly influence your decision in selecting the right tool for local Kubernetes development. RAM: my testing on k3s (mini k8s for the 'edge') seems to need ~1G on a master to be truly comfortable (with some addon services like metallb, longhorn), though this was x86 so memory usage might vary somewhat slightly vs ARM. Or check it out in the app stores Home; Popular; TOPICS.

You will get the same Kubernetes and Kubernetes resources in both: Pod, Deployments, ConfigMaps, StatefulSets, I think of K3s as being best for a single application cluster and/or where resources are going to be limited. 0. That is not k3s vs microk8s comparison. But I cannot decide which distribution to use for this case: K3S and KubeEdge. On the other hand, using k3s vs using kind is just that k3s executes with containerd (doesn't need docker) and kind with docker-in-docker. Each of these tools boasts a unique set of capabilities, perfectly suited to specific scenarios. When it comes to k3s outside or the master node the overhead is non existent. I create the vms using terrafrom so I can take up a new cluster easily, deploy k3s with ansible on the new vms. k0s binary is massive (170MB) compared to k3s (50MB). kubeadm: kubeadm is a tool provided by Kubernetes that can be used to create a cluster on a single Raspberry Pi.

K0s, K3s, and K8s are three different orchestration systems used to deploy and manage containers. 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 Kubernetes on IoT devices that can't run K3s. Installing k3s. As a homelab, go with proxmox cos it's easier to start afresh if u when u r running some kind of experiment, or when u screw up This subreddit has gone Restricted and reference-only as part of a mass protest against Reddit's recent API changes, which break third-party apps and moderation tools.

Valheim; Genshin Impact; Minecraft; Pokimane; Halo Infinite; Call of Duty: Warzone; Distributions like k3s make getting up and running comparatively easy, so I think there’s not too much harm in it even if it’s technically overkill. Let me know about your experiences or other tools that you use to setup a local Kubernetes cluster. k3d, a featherweight in local Kubernetes deployment, shares a similar approach to kind but opts for deploying a lightweight k3s instead of standard Kubernetes. For immediate help and problem I use k3s for this usecase, but there is quite a bit of overhead (10-20% CPU maybe? and like 300-400 MB of ram) just from running k3s itself, even without traefik and local-path-provisioner that it installs by default. Internet Culture (Viral) Amazing; Animals & Pets; Cringe & Facepalm; Funny; Interesting; Memes; Oddly Satisfying; Alternatively k3s on a single node is great, I have multiple single-node clusters that run k3s and it allows for really good way to standardize MiniKube. It was designed for Edge but kind of grew past that, and is used for running a lot of on-prem clusters and home labs, because it is more Initially I did normal k8s but while it was way way heavier that k3s I cannot remember how much. Otherwise, k3s or vanilla k8s for on prem. But that was a long time ago. It is made by Canonical (Ubuntu). In this respect, K3s is a little more tedious to use than Minikube and MicroK8s, both of which provide a much simpler process for adding nodes. In particular, I need deployments without downtimes, being more reliable than Swarm, stuff like Traefik (which doesn't exist for Docker Swarm K3S, OKD, etc are find with a single node but they will need the proxy once you scale up two three, and in Kubernetes scaling is 1 or 3. Qemu becomes so solid when utilizing kvm! (I think?) The qemu’s docker instance is only running a single container, which is a newly launched k3s setup :) That 1-node k3s cluster (1-node for now. K3S seems more straightforward and more similar to actual Kubernetes. Also you can have few ingresses. Meet Minikube, KinD (Kubernetes in Docker), and k3d (K3s in Docker) — three prominent players that frequently surface in Kubernetes development conversations.

So maybe you run K3s or Minikube or KinD for a dev environment, and then use something like Kubeadm or a cloud-managed offering for a production K8s cluster. rke2 is built with same supervisor logic as k3s but runs all control plane components as static pods. This also means that you should be able to use kind no matter what your use case is. clusters should be kept over provisioned just in case of the "scaling speed throttle". flant. Then most of the other stuff got disabled in favor of alternatives or newer versions. If you're trying to run k3s in a high availability cluster (meaning 3 control planes) then you have to use etcd.

Linus Tech Tips - My network is bigger From the site: K3s is a highly available, certified Kubernetes distribution designed for production workloads in unattended, resource-constrained, remote locations or inside IoT appliances I'd happily run it in production (there are also commercial managed k3s clusters out there). A couple differences to note - the Sixge K3S has a "diagonal" cutout pattern at the corners of the side panel holes vs the Acat which has "square" corners like Louqe. Eventually they both run k8s it’s just the packaging of how the distro is delivered. It's a very flexible set up. From there, really depends on what services you'll be running. There’s no point in running a single node kube cluster on a device like that. So now I'm wondering if in production I should bother going for a vanilla k8s cluster or if I can easily simplify everything with k0s/k3s and what could be the advantages of k8s vs these other distros if any. Reply reply 27 votes, 37 comments. Use k3s for your k8s cluster and control plane. Because I only have one hypervisor, I'm only running a single-node k3s cluster (it's the control plane, etcd, and the worker): Nginx for today is kind of standard.

Why at all (I am probably missing some kind of use of this idea) would I It has Okta integration, kind of. I have used k3s in hetzner dedicated servers and eks, eks is nice but the pricing is awful, for tight budgets for sure k3s is nice, keep also in mind that k3s is k8s with some services like trafik already installed with helm, for me also deploying stacks with helmfile and argocd is very easy to.
