K3s reddit I'm learning K3s at home on a single-node cluster (I don't need redundancy, yet). 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. Hi all, I would like to build a k3s raspberry pi cluster and use it to host bitwarden (vaultwarden) over it (among other things). I'm now looking at a fairly bigger setup that will start with a single node (bare metal) and slowly grow to other nodes (all bare metal), and was wondering if anyone had experiences with K3S/MicroK8s they could share. dev ops engineer or something related to it. It's installable from a 40 MB binary. Hi everyone, I have recently started learning kubernetes, ansible, docker, and etc around two weeks ago to become either a jr.

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 K3s is a binary that can run on technically any Linux OS, and configured to your specific needs. K3s: stale file handles on nfs volumes Hello, I setup K3s on some Raspberry Pi 3 and it almost works perfectly. Get the Reddit app Scan this QR code to download the app now. Wiping k3s off the OS is very easy and pretty much brings the OS back to its stock state. Also, whenever i try to restart my machine the k3s won't boot up and have some issues in it shim. Terraform is HashiCorp's infrastructure as code (IaC) tool that can be used to manage infrastructure deployments and configuration across a plethora of providers and tools, including Azure, AWS, GCP, Docker and 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. Reply reply 27 votes, 37 comments. S3 and CloudFront are designed by people who have expertise in writing highly scalable, available, fast, and redundant applications. I'd go k3s or ranchers commercialised version of it long before touching openshift with anything other than thermite. Agreed, when testing microk8s and k3s, microk8s had the least amount of issues and have been running like a dream for the last month! PS, for a workstation, not edge device, and on Fedora 31 Reply reply I have installed k3s for one node cluster as suggested by this community. It did great until I got stuck using ARM incompatible images and less memory to play around with. It seems to be lightweight than docker. Easily create multi-node Kubernetes clusters with K3s, and enjoy all of K3s's features Upgrade manually via CLI or with Kubernetes, and use container registries for distribution upgrades Enjoy the benefits of an immutable distribution that stays configured to your needs It’s doing none of the extra things that k3s is doing or any kube for that matter, which would be negated by running as a single node. By default with k3s, the server (master) and an agent (worker) are running on the same node. I have setup monitoring for a single node K3s cluster yesterday. I can only connect one source to it, and I would like to connect more than one source. The last I'm sorry to hear that you had difficulty connecting to your on-prem K3s clusters and that the UI didn't provide enough feedback for you to troubleshoot the issue. I enjoyed the process of over engineering things and so now I present to you UltimateHomeServer - UltimateHomeServer is a user-friendly package of open-source services that combine to create a powerful home server, capable of replacing many of The K3s specifies it uses a reverse proxy config: k3s uses reverse tunneling such that the nodes make outbound connections to the server and all kubelet traffic runs through that tunnel. 04, and the user-space is repackaged from alpine. rke2 is built with same supervisor logic as k3s but runs all control plane components as static pods. No, it is not a fork of Kubernetes. --- If you have questions or are new to Python use r/LearnPython I've recently watched a lot videos on Consul and K3s and it seems like a lot of the concepts with these setups are the same. 5mm, and a bass boost if you are so inclined. 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. Production ready, easy to install, half the memory, all in a binary less than 100 MB. K3s is a minified version of Kubernetes developed by Rancher Labs. I think this max volume is pushing the highest level that I should be using the 6XX at long-term anyway, I wouldn't want it any higher. But honestly you can just use straight k8s manifests in k3s (there is a special folder where k3s loads manifest files automagically). CNI is Cilium (love it) and PortWorx is used for distributed storage. k3s and rke in tons of production clusters, each has its place. k3s: uses sqlite as DB which is suboptimal, you should be able to look inside the etcd DB with the cli and be familiar with some basic operations, at least know where the docs are K8s the hard way: doesn't setup proper networking, it relays entirely on Google cloud magic. It also has k3s built in. As to the people talking about k3s and external backends, ex: mariadb/mysql, If you go this route you are responsible for providing the HA cluster for thay backend service (load balancer with at min 3 mariadb galera nodes). We tend to everything through Google Kubernetes Engine but some of our clients wants the infrastructure to be hosted on their own machines due to security policies. Portainer started as a Docker/Docker Swarm GUI then added K8s support after. Do you guys run databases in Kubernetes, or do you run them outside your cluster? If you do run them in the cluster, how do you handle backups? Hi, I've been using single node K3S setup in production (very small web apps) for a while now, and all working great. That is not k3s vs microk8s comparison. I've been reading around to learn more and I figured we should deploy three k3s servers and three workers. I have being running the K3 for a long time and have being extremely happy with it for desktop music, videos and gaming use. We would like to show you a description here but the site won’t allow us. 6 and a local Git server.

I'm trying to setup Kubernetes on my home server(s). 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. When i run my container with ctr, its loading the gpu, but inside the k3s its not. From reading online kind seems less poplar than k3s/minikube/microk8s though. Before kind I used k3s but it felt more permanent and like something I needed to tend and maintain. On each one is a controller node and a worker node. Installing k3s. Try Oracle Kubernetes Engine. Or check it out in the app stores Yup, just install an os and K3S!

It's made by Rancher and is very lightweight. If you don't need as much horsepower, you might consider a Raspberry Pi cluster with K8s/K3s. Virtualization is more ram intensive than cpu. K3S is legit. Kubernetes is pretty easy to use but has a high learning curve. I want to create my own little Kubernetes cluster on Hetzner Cloud using k3s. I think Rancher has another storage solution which is compatible with K3s. Deploy a few applications and look up any concepts that you dont understand. Eventually they both run k8s it’s just the packaging of how the distro is delivered. 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. Reason why I ask is if I should bother learning the full fledge k8s or is learning with k3s/microk8s enough? I am not a developer but I am building my career towards devops/sre. Rancher is not officially supported to run in a talos cluster (supposed to be rke, rke2, k3s, aks or eks) but you can add a talos cluster as a downstream cluster for management You’ll have to manage the talos cluster itself somewhat on your own in that setup though; none of the node and cluster configuration things under ranchers “cluster At home, I run a single-node k3s with a low workload, but I have no experience whatsoever configuring multi-node setups. So how would k3s be worth the extra resource consumption and offer anything more than simple podman with systemd? Use RKE2 if you want something Rancher-flavored and more production ready. The K3s team plans to address this in the future. The embedded sqlite doesn't replicate between master nodes. I have been using a simple Fiio K3 for a few years, and it has served me well till now.

Reply reply [deleted] Welcome to /r/SkyrimMods! We are Reddit's primary hub for all things modding, from troubleshooting for beginners to creation of mods by experts. Those six nodes are then connected to a router with load-balancing. Access to Disk - I can manage the disk access. Maybe I'm dumb but I just don't get Helm. This results in a single binary with a size of around 60 MB. fix failover problem [make sure that failover occurs faster, pods are being created on other nodes faster]: My use case is RPi cluster, mostly for tinkering and homelabbing, so I have made an Alpine Linux overlay that installs k3s. When it comes to k3s outside or the master node the overhead is non existent. I've deployed the entire setup using ArgoCD 2. But that sounds like a nightmare of a learning curve for developers! These are web developers who don't know what a container is, and QA testers who are only familiar with static environments. 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.

Some co-workers recommended colima --kubernetes, which I think uses k3s internally; but it seems incompatible with the Apache Solr Operator (the failure mode is that the zookeeper nodes never reach a quorum). Yes, i know that i can use instead only Docker Compose or Portainer, but i had previosly the oportunity to work with Nomad, and appears to me very simple to setup and manage in comparison with k8s, considering that i can setup k3s/k0s too. I was reading forums about longhorn and how its a good distributed storage system. K3s obvisously does some optimizations here, but we feel that the tradeoff here is that you get upstream Kubernetes, and with Talos' efficiency you make up for where K8s is heavier. The only difference is k3s is a single-binary distribution. Considering that I think it's not really on par with Rancher, which is specifically dedicated to K8s. This would then result in the HA required for us. The conclusion here seems fundamentally flawed. Working with Kubernetes for such a long time, I'm just curious about how everyone pronounces the abbreviation k8s and k3s in different languages?

Unlike the previous two offerings, K3s can do multiple node Kubernetes cluster. Note: I don’t work for/with anybody that’s affiliated with Rancher, k3s, or k3d. I plan to use Rancher and K3s because I don't need high availability. Rancher is great, been using it for 4 years at work on EKS and recently at home on 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 has some nice features, like Helm Chart support out-of-the-box. However, most failover setups actually require a minimum of 3 nodes so that they can have a quorum. That's why the container is stuck in Terminating. other Kubernetes distributions is its broad compatibility with various container runtimes and Docker images, significantly reducing the complexity associated with managing containers. I use K3S heavily in prod on my resource constricted clusters. I'm new into Kubernetes and just starting out. Setup just took a few minutes. You're paying a big premium for their API, reliability, feature set, and expertise in running global data centres. But if it's for a learning\play around i'd suggest looking at one of the cloud providers first. Hi all I’ve been using K3 on a pi cluster for the longest time. We ask that you please take a minute to read through the rules and check out the resources provided before creating a post, especially if you are new here. We are Reddit's primary hub for all things modding, from and now it is like either k3s or k8s to add i am looking for a dynamic way to add clusters without EKS & by using automation such as ansible, vagrant, terraform, plumio as you are k8s operator, why did you choose k8s over k3s? what is easiest way to generate a cluster. io | sh -s - --disable=traefik --disable=servicelb. With the HD 6XX plugged into the 3. Given proxmox is installed on top of Debian, I’m just wondering if anyone can think of a reason why I couldnt, or shouldn’t, install k3s on it alongside proxmox. k3s is very good and can be run on most distros. It also is fully API compatible with Kubernetes so you could use it in a dev environment or low capacity production environment (low resource hardware). Now I want to host some small private projects (like node server and db) and was looking for a simple managing software. Rock solid, easy to use and it's a time saver. Didn't get to install on actual hardware, just skimmed through the docs but eventually went with k3s and longhorn, very pleased with the results so far. And it is time to upgrade because I need more input sources; optical input, USB and Bluetooth (everything has Bluetooth and I just want to use my nice headphones). 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 It really depends. Quick question. true. Thanks to the native Ansible modules for HashiCorp Vault, it's easy to retrieve secrets / add new secrets. Longhorn getting stuck in Attaching is downstream of this issue. With k3s you get the benefit of a light kubernetes and should be able to get 6 small nodes for all your apps with your cpu count. Giving the rpi’s fast storage would be great. Since I also wanted to experience on running kubernetes on my own, I needed new hardware to run a full k3s cluster with a minimum of one server node and two agent Only recently I learned that QNAP's container station ships with built-in k3s: Container Station | Supports LXD, Docker, and Kata Containers | QNAP… A place for discussion, news, reviews and DIY projects related to portable audio, headphones, headphone amplifiers and DACs. Atlantis for Terraform gitops automations, Backstage for documentation, discord music bot, Minecraft server, self hosted GitHub runners, cloud flare tunnels, unifi controler, grafana observability stack and volsync backup solution as well as cloud native-pg for postgres database and GCP and Azure have similar costs. Using K3S allowed us to use the same deployment steps for both cloud and on premises setups. 5mm port on the K3, they sound more than loud enough at max with the gain on. Everything started to made sense once I spin up a few VMs and installed a k3s cluster. Something like here is my git repo and my config - Make it online. I installed k3s on everything and deployed a test application which worked. 0. A bit like my own vercel. k3s offers a few ways to do HA -- but unless you are running the datastore externally (usually with some managed database service like postgres on RDS, etc), you'll be using the built-in etcd support. Unveiling the Kubernetes Distros Side by Side: K0s, K3s, microk8s, and Minikube ⚔️ I took this self-imposed challenge to compare the installation process of these distros, and I'm excited to share the results with you. tom lscimn pzblz giea nnyvicm gyosntom ffmm kxd tiuge xbjme dkfdm tzr wqdi dxax dbsim
