Hi, so I'm trying to set up a single node k3s cluster on Oracle's free arm instance and I'm facing some problems when trying to install MetalLB (trying to set up subdomains on a single host managed by the ingress). I am evaluating using k3s on edge devices. All I can see in their docs is that k3s is lightweight and a good choice for edge devices. i build a small k3s cluster to lern kubernetes. Gitpod. I'm at the point now where I need to make a decision on storage. I choose not to PXE boot because of the overhead due to the only thing I have installed on Debian 12 is k3s. Both seem suitable for edge computing, KubeEdge has slightly more features but the documentation is not straightforward and it doesn't have as many resources as K3S. Any issues encountered? It's important to note that k3s isn't just for Pi/homelab setups. Come and join us today! Members Online My setup is based on a bare-metal cluster running on Debian with k3s, Longhorn for storage, and Traefik for SSL certificates and reverse proxy handling. I started with home automations over 10 years ago, home-assistant and node-red, over time things have grown. Trying to get an NVIDIA GPU to work in my Plex container running in k3s, single node cluster, within a proxmox VM. I don't get it, if k3s is just a stripped down version of k8s, what's different about its memory management so that having swap enabled isn't an issue? I've been experimenting with both Proxmox-virtualized k3s and bare-metal k3s. I have all the k3s nodes on a portgroup with a VLAN tag for my servers. 28 added beta support for it. All about small form factor PCs – decreasing size and maximizing space efficiency! Do you have any resources at hand which describe your setup with k3s and multus? E. I work in the self-hosted team, so we have to support all managed forms of Kubernetes, but my preference is always k3s because it's just so straightforward and k3sup simplifies the setup process even further. I will host mostly some private development stuff and tools but also some stuff that I don't want to be down when I'm doing some maintenance or other r/k3s: Lightweight Kubernetes. Defaults are fine for a typical micro lab cluster. I would use either based on the Has anybody had any luck deploying k3s on M1 (Apple Silicon)? I assume the only way is using Asahi Linux (https://asahilinux. The IRS is experiencing significant and extended delays in processing - everything. Hard to speak of “full” distribution vs K3S. I like to implement some sort of monitoring. Don't post questions related to that here, please. So far I'm experimenting with k3s on multiple photon VMs on the same physical host, for convenience, but I think I'm going to switch to k3s on Raspberry Pi OS on multiple Raspberry Pi 4B nodes for the final iteration. Unlike the previous two offerings, K3s can do multiple node Kubernetes cluster. Not only is k3s great for learning Kubernetes, it can and should be used in a lot of production scenarios. Or check it out in the app stores Kubeadm, Kind and K3S. maintain and role new versions, also helm and k8s K3s is a stripped down version of K8s, mostly with cloud components removed, and is much more lightweight in terms of resource useage. A couple of downsides to note: you are limited to flannel cni (no network policy support), single master node by default (etcd setup is absent but can be made possible), traefik installed by default (personally I am old-fashioned and I prefer nginx), and finally upgrading it can be quite disruptive. Using K3S allowed us to use the same deployment steps for both cloud and on premises setups. Any Kafka offering which can be installed on k8s should work on k3s, as long as you have the right storage set up and are aware of the limitations of your infra (e. docs Check out Rancher and K3s, it may get you close enough to your goal set up with a few less moving parts. But I cannot decide which distribution to use for this case: K3S and KubeEdge. service and it will redeploy traefik if it is missing If that doesnt work, maybe try forcing it: add "--no-deploy traefik" option when starting k3s. First guess will always be to check your local firewall rules. Hi all, I would like to build a k3s raspberry pi cluster and use it to host bitwarden (vaultwarden) over it (among other things). K3s has some nice features, like Helm Chart support out-of-the-box. When I first started I spent weeks reading up on kubernetes, k3s but hardly understanding anything. We are Reddit's primary hub for all things modding, from Rancher's K3s and RKE2 are both open-source Kubernetes distributions that can be used to deploy and manage containerized applications. Even though I use a mix of systems, I prefer using bare metal and some of the people I meet at some of the like the k8s at home people have raspberry For k3s, it would be the same as docker. It uses DID (Docker in Docker), so doesn't require any other technology. I dont want to use them, because i like to lern something restart the k3s. Eh, it can, if the alternative is running docker in a VM and you're striving for high(ish) availability. Would probably still use minikube for single node work though. By default with k3s, the server (master) and an agent (worker) are running on the same node. However, looking at its GitHub page, it doesn't look too promising. There is more options for cni with rke2. Hello, I have the following extra config in k3s: transfer { to * } I add id by running, kubectl edit configmap coredns -n kube-system But when… k3s is just a specific (cncf conformant) distribution of k8s. 0. io | sh -s - --disable=traefik --disable=servicelb.

Im using k3s, considering k0s, there is quite a lot of overhead compared to swarm BUT you have quite a lot of freedom in the way you deploy things and if you want at some point go HA you can do it (i plan to run 2 worker + mgmt nodes on RPI4 and ODN2 plus a mgmt only node on pizero) Hi ya'll 👋 this is a template repository for creating a k3s cluster with k3sup backed by Flux and SOPS. Prod: managed cloud kubernetes preferable but where that is unsuitable either k3s or terraform+kubeadm. New comments cannot be posted and votes cannot be cast. For the benefits of terraform: It has a big community, I can use the helm provider (which allows staggered deploys compared to k3s helm operator) and it's declarative allowing for easier IaC. The ESP32 series employs either a Tensilica Xtensa LX6, Xtensa LX7 or a RiscV processor, and both dual-core and single-core variations are available. Also: MicroOS is really nice. I think Rancher has another storage solution which is compatible with K3s. I was looking for a solution for storage and volumes and the most classic solution that came up was longhorn, I tried to install it and it works but I find myself rather limited in terms of resources, especially as longhorn requires several replicas to work Hello fellow k3s admins.

In Chinese, k8s may be usually pronounced as /kei ba es/, k3s may be usually pronounced as /kei san es/. I've read some articles and watched some videos about it but I can't figure out how to design my cluster correctly. K3s is a lightweight certified kubernetes distribution. Over the weekend in my lab I was playing with OIDC as a means of authenticating to the cluster without using the default root account. My use case is RPi cluster, mostly for tinkering and homelabbing, so I have made an Alpine Linux overlay that installs k3s. I’d love to hear pros/cons from others. Another option I'd consider is k3s, because it has the same workflow as Kubernetes itself while abstracting all the components that we would manage for our customers. xyz. Been a proper pain in the ass (edit: but also fun and useful) to make though because of a learning curve. A place to discuss and share your addressable LED pixel creations, ask for help, get updates, etc. Deploy a few applications and look up any concepts that you dont understand. log file to see why they didn't rejoin the cluster. Depending on your risk tolerances, you may find k3s/k0s as harder to bet your business on than unmodified upstream Kubernetes, since they optimize for simplicity by making compromises to state storage/HA capabilities, etc. Everything started to made sense once I spin up a few VMs and installed a k3s cluster. 0, but it takes a long time to provision. org/), and installing k3s there?

Oct 20, 2024 · Moved my stack to Kubernetes (running on K3S) about 8 months ago, mostly as an excuse to get up to speed with it in a practical sense (we have a K3s is a highly available, certified Kubernetes distribution designed for production workloads in unattended, resource-constrained, remote locations or inside IoT appliances. I'm in the same boat with Proxmox machines (different resources, however) and wanting to set up a kubernetes type deployment to learn and self host. Should I just install my K3S master node on my docker host server. Longhorn getting stuck in Attaching is downstream of this issue. I plan to use Rancher and K3s because I don't need high availability. 04, all good so far. But if you need a multi-node dev cluster I suggest Kind as it is faster. Note: whatever you do, don’t use ZFS. My initial plan was to build it around a couple of Raspberry Pi's, but I wanted the setup to be reproducible and easy to reprovision, meaning more IaC and less direct interaction with the nodes. S. What's the advantage of microk8s? I can't comment on k0s or k3s, but microk8s ships out of the box with Ubuntu, uses containerd instead of Docker, and ships with an ingress add-on. Giving the rpi’s fast storage would be great. I can't really decide which option to chose, full k8s, microk8s or k3s. Keen to hear about your experiences with Hetzner and k3s. I just really got a LOT of value out of k3d + k3s as a beginner. Hope this helps! 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 deployment methods across multiple sites Reply reply More replies Raspberry Pi k3s high-availability cluster deployed with Ansible: /r/StableDiffusion is back open after the protest of Reddit killing open API access, which will I haven’t tried k3s yet, but I’m planning on using my rpi’s ( 2 4s and 1 3b) as managers and then 2 (later 3) Intel PCs as workers. The K3s team plans to address this in the future. However, due to technical limitations of SQLite, K3s currently does not support High Availability (HA), as in running multiple master nodes. The purpose here is to showcase how you can deploy an entire Kubernetes cluster and show it off to the world using the GitOps tool Flux. That's why the container is stuck in Terminating. I couldn't find anything on the k3s website regarding swap, and as for upstream kubernetes, only v1. Struggling with Kubernetes cluster management on Hetzner, I created a streamlined tool. I find that the easiest way to start is to just start with a few VMs. This might trigger the autodeploy. I ditched that and I got a ipv6 segment from my provider (numbers changed) 2a00:a100:b000:1000::/56 and WAN IP address for my router 2a00:a100:b000:1000::30 . My question is, or what I don't quite understand yet, if vaultwarden is running on worker 1, and worker 1 fails, does vaultwarden conti It really depends. Hi friends, I've deployed K3s on Ubuntu 18. You need to explicitly disable the schedeling of workloads on server node to get a dedicated "master" (like the Kubernetes you could bootstrap with kubeadm) I'm trying to deploy my web app to a basic K3s installation, but in the JS console I keep getting errors about WebSocket not being able to connect. So far, I have setup K3s itself, Helm, Flux, and a few applications (all deployed via Flux) that don't require storage. So when you stop k3s the control plane has no way to know that the container has stopped as well. I have a couple of dev clusters running this by-product of rancher/rke. It won’t work with K3s properly. We're actually about to release a native K8s authentication method sometime this week — this would solve the chicken and egg ("secret zero") problem that you've mentioned here using K8s service account tokens. There were none. K3S seems more straightforward and more similar to actual Kubernetes. and International, Federal, State, or local. i tried kops but api server fails everytime. io (my employer) is run on it. Oh, and even though it's smaller and lighter, it still passes all the K8s conformance tests, so works 100% identical. From Docker (-Compose) to K3s? I've asked this once before, around (or over) a year ago and had a nice conversation and got the conclusion 'not worth it'. I'm not too great with Traefik, but here's the ingress configuration: k3s process includes both the containerd container runtime and kubelet. Even though there’s all kinds of fancy stuff out there, these days (like tilt)…I still default to k3d when I need to quickly spin up a small throw-away cluster locally. The downside of using k3s is that it is minimal because it trims out a lot of components that most use cases don't need but are there for backwards compatibility or edge cases. It also has a hardened mode which enables cis hardened profiles. The Master+Nodes are VMs running KVM on a Ubuntu host machine. 04, and the user-space is repackaged from alpine. A nginx deployment with two replicas took over 20 minutes to be ready. Doing high availability with just VMs in a small cluster can be pretty wasteful if you're running big VMs with a lot of containers because you need enough capacity on any given node to In a highly available K3s Cluster, is a load balancer needed or can you utilize the Traefik Ingress Controller and load balancer (Klipper) that’s included in the install? Archived post. As I already have office 365 for my self, I get access to entra (FKA Azure AD) The (un)official home of #teampixel and the #madebygoogle lineup on Reddit. I used Dell Optiplex 790's and a custom ryzen machine (I use flux2 to sync my changes from a git repo to the cluster). 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. You are going to have the least amount of issues getting k3s running on Suse. I would wonder if your k3s agents are starting at boot -- or, if they are, check the k3s-service. Take a look and let me know which I like k0s, k3s is nice too. We want all of these to be part of a single k3s cluster. Suse releases both their linux distribution and Rancher/k3s. 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 compliance in government/financial clusters so they are targeting different areas that really need K3S on the other hand is a standalone, production ready solution suited for both dev and prod workloads. Eventually they both run k8s it’s just the packaging of how the distro is delivered. I use K3S heavily in prod on my resource constricted clusters. It's made by Rancher and is very lightweight. Alternatively, if want to run k3s through docker just to get a taste of k8s, take a look at k3d (it's a wrapper that'll get k3s running on I used to have a fixed ipv4 to access my hobby K3s cluster. Was put off microk8s since the site insists on snap for installation. K3s is packaged as a single <70MB binary that reduces the dependencies and steps needed to install, run and auto-update a production Kubernetes cluster. RKE2 is more for your traditional kubernetes installation where scalability is more of the goal. com resolves to my k3s single control plane node I had previously used the TrueCharts helm chart to install truecommand but I had this same problem and originally I thought it was the chart, so I'm writing my own config files here If you want to install a linux to run k3s I'd take a look at Suse. We are Using k3s on our edge app, and it is use as production. avvrbo vehpfmrq ccuixk gage nmb sutupgf nnsm zmvm bvrhrtec yofpkx xcyan bfacpba ejjku tdomwgt tfe
