K3s reddit I got k3s installed on a cluster of Raspberry Pi's, but the availability doesn't actually work. K3s is a minified version of Kubernetes developed by Rancher Labs. Thanks to the native Ansible modules for HashiCorp Vault, it's easy to retrieve secrets / add new secrets. Oracle Cloud actually gives you free ARM servers in total of 4 cores and 24G memory so possible to run 4 worker nodes with 1 core 6G each or 2 worker nodes with 2 cores and 12GB memory eachthen those of which can be used on Oracle Kubernetes Engine as part of the node pool, and the master node itself is free, so you are technically K3s is made to work fine out of the box on a single node if desired. 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. We would like to show you a description here but the site won’t allow us. With the HD 6XX plugged into the 3. With a single node of anything, you’re getting a lesser version oh HA no matter what. Hope this helps! If you ever add a second machine, you could always expand your k3s cluster later to separate masters and workers, but fundamentally, if you only have one viable host, there's no reason you shouldn't just run a "hyperconverged master" :) Cilium will take care of the loadbalancer IPs pool and L2 announcements, current deployment setup replaces also several k3s components, like local-storage, servicelb, traefik, flannel-backend, kube-proxy, cloud-controller and network-policy. 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. Cilium's "hubble" UI looked great for visibility. My initial setup was to have 2 nodes in case one goes down. K3s Cluster Creation: Using Terraform to create a K3s cluster (with HA mode, minimum of 2 VMs) for Rancher hosting and additional services like AWX. Get support, learn new information, and hang out in the subreddit dedicated to Pixel, Nest, Chromecast, the Assistant, and a few more things from Google. io | sh -s - --disable=traefik --disable=servicelb. Best I can measure the overhead is around half of one Cpu and memory is highly dependent but no more than a few hundred MBs The fiio k3 is awesome. 0. Longhorn getting stuck in Attaching is downstream of this issue. 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. There’s no point in running a single node kube cluster on a device like that. Installing k3s. For example I use k3s to run HA clusters on prem with kube-vip and nginx (ingress controller). For experienced developers. In case you want to use k3s for the edge or IoT applications, it is already production ready. . Giving the rpi’s fast storage would be great. Yes, it is possible to cluster the raspberry py, I remember one demo in which one guy at rancher labs create a hybrid cluster using k3s nodes running on Linux VMs and physical raspberry py. Quick question. 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. practicalzfs. Take a look and let me know which 34 votes, 36 comments. So far, I have setup K3s itself, Helm, Flux, and a few applications (all deployed via Flux) that don't require storage. I guess it's just easy to have it in my cluster repo if I use it anyways. Hi all I’ve been using K3 on a pi cluster for the longest time. 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. I'd probably recommend a single node cluster deployed in the same manner as your production cluster running either hosted with us, or installed on your own computer. You're paying a big premium for their API, reliability, feature set, and expertise in running global data centres. That's why the container is stuck in Terminating. It's made by Rancher and is very lightweight. A bit like my own vercel. 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. Try Oracle Kubernetes Engine. true. Vanilla Kubernetes deployed with Kubespray on RHEL VMs in a private cloud (spread across three data centers). Virtualization is more ram intensive than cpu. I'm at the point now where I need to make a decision on storage. I have setup monitoring for a single node K3s cluster yesterday. 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. When i run my container with ctr, its loading the gpu, but inside the k3s its not. I feel like at that point though, you're better off with going with something like k3s that is better documented. btw. It consumes the same amount of resources because, like it is said in the article, k3s is k8s packaged differently. Good luck! For example, in a raspberry py, you wouldn't run k3s on top of docker, you simply run k3s directly. If you just want a pretty UI, then deploy different tools to your cluster until you find something you like. 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. 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. k3s and rke in tons of production clusters, each has its place. 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. I already have strong experience with CI/CD pipelines and cloud exposure with AWS where I've dealt ELB's, EC2's, ASGs etc I just haven't got the chance to use EKS. Berkhan takes a detailed look into the $119,99 USD FiiO K3s, the company's Fiio New K3 model for 2021. 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. maintain and role new versions, also helm and k8s The (un)official home of #teampixel and the #madebygoogle lineup on Reddit. Given that information, k3OS seems like the obvious choice.

Of course, I also hope anyone else in this reddit finds my guides useful or even inspiring! These guides are essentially all about the software setup, since the hardware part is a no-brainer. It cannot and does not consume any less resources. Everything started to made sense once I spin up a few VMs and installed a k3s cluster. Production ready, easy to install, half the memory, all in a binary less than 100 MB. service, not sure how disruptive that will be to any workloads already deployed, no doubt it will mean an outage. However, looking at its GitHub page, it doesn't look too promising. The only difference is k3s is a single-binary distribution. io/ k3s is a "batteries included" distribution that grows with you. I'd go k3s or ranchers commercialised version of it long before touching openshift with anything other than thermite. The embedded sqlite doesn't replicate between master nodes. Everybody talks about Helm, it's preinstalled with stuff like k3s and yeah, Helm is the way to go. Or check it out in the app stores Yup, just install an os and K3S! I setup a K3S cluster on a Count me in the group that runs k3s which is a slimmed down version of k8s . When I first started I spent weeks reading up on kubernetes, k3s but hardly understanding anything. k3s is very good and can be run on most distros. I’m using an NFS (by utilizing the Kubernetes NFS Subdir provisioner). So when you stop k3s the control plane has no way to know that the container has stopped as well. K3s is a lightweight certified kubernetes distribution. It's tiny, well built, has a satisfying volume knob, high and low gain, balanced 2. The last two years I have been using a Raspberry PI 4B with 8GB RAM running docker. I plan to use Rancher and K3s because I don't need high availability. 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. Portainer started as a Docker/Docker Swarm GUI then added K8s support after. Storage is certainly an issue for these minimal type distros. Hi everyone, I have recently started learning kubernetes, ansible, docker, and etc around two weeks ago to become either a jr. Access to Disk - I can manage the disk access. That is a pretty liberal definition of "HA" with the cluster database running on a single instance MySQL container This mode of operation is really designed to be used against an existing external database that is already employing some form of HA strategy; otherwise k3s supports embedded etcd which would be more appropriate. For K3S it looks like I need to disable flannel in the k3s. From reading online kind seems less poplar than k3s/minikube/microk8s though. I started with home automations over 10 years ago, home-assistant and node-red, over time things have grown. 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. ” To be honest even for CI/CD can be use as production. My preference would have been for OS Parity but in reality bar a few edge cases it doesn't matter. If you already have something running you may not benefit too much from a switch. By default with k3s, the server (master) and an agent (worker) are running on the same node. 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). Check out how it performs on Headfonia. I use k3s with kube-vip and cilium (replacing kube-proxy, thats why I need kube-vip) and metallb (will be replaced once kube-vip can handle externalTrafficPolicy: local better or supports the proxy protocol) and nginx-ingress (nginx-ingress is the one i want to replace, but at the moment I know most of the stuff of it). “designed for production workloads in unattended, resource-constrained, remote locations or inside IoT appliances. I've been reading around to learn more and I figured we should deploy three k3s servers and three workers. other Kubernetes distributions is its broad compatibility with various container runtimes and Docker images, significantly reducing the complexity associated with managing containers. Hello, I'm setting up a small infra k3s as i have limited spec, one machine with 8gb ram and 4cpu, and another with 16gb ram and 8cpu. Use k3s for your k8s cluster and control plane. I’d love to hear pros/cons from others. My server is just a testing homelab, and it would be nice to get native ram, disk and cpu instead of locking it inside a lxc/vm. Credit: How K3s works Jul 24, 2023 · A significant advantage of k3s vs. Although K3s is a refined version of Kubernetes (the upstream version), it does not change how Kubernetes works at its core. It uses DID (Docker in Docker), so doesn't require any other technology. I was reading forums about longhorn and how its a good distributed storage system. S. 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) This sub-reddit is dedicated to everything related to BMW vehicles, tuning, racing, and more. It also has a hardened mode which enables cis hardened profiles. 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. 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. I can't really decide which option to chose, full k8s, microk8s or k3s. 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. TLDR; Which one did you pick and why? How difficult is it to apply to an existing bare metal k3s cluster? Initially I did normal k8s but while it was way way heavier that k3s I cannot remember how much. K3s is a certified Kubernetes distribution. dev ops engineer or something related to it. When it comes to k3s outside or the master node the overhead is non existent. If you are wondering what Amateur Radio is about, it's basically a two way radio service where licensed operators throughout the world experiment and communicate with each other on frequencies reserved for license holders. Those six nodes are then connected to a router with load-balancing. I have being running the K3 for a long time and have being extremely happy with it for desktop music, videos and gaming use. I run bone-stock k3s (some people replace some default components) using Traefik for ingress and added cert-manager for Let's Encrypt certs. To download and run the command, type: Hard to speak of “full” distribution vs K3S. I can only connect one source to it, and I would like to connect more than one source. But then, when you look at Artifact Hub for some charts it seems that like nobody, really no one ever is actually using those charts, this website has less traffic than my personal website when I was 15, charts there have little to zero stars, last I chose k3s because it's legit upstream k8s, with some enterprise storage stuff removed. P. It also has k3s built in. Rancher's K3s and RKE2 are both open-source Kubernetes distributions that can be used to deploy and manage containerized applications. Reply reply Get the Reddit app Scan this QR code to download the app now. 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 features and customization options. 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. That is not k3s vs microk8s comparison. Something like here is my git repo and my config - Make it online. 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 Hi all! As the topic titled, is the dac(not amp) of K3 any good and produces good quality of sound? It was gifted to me and I’m planning to use a dedicated amp with it (Liquid Spark by Monolith) for my Fostex T60rp and Philips Fidelio L2, but not sure about the dac of K3. The K3s team plans to address this in the future. Digital Rebar supports RPi clusters natively, along with K8s and K3s deployment to them. Maybe I'm dumb but I just don't get Helm. The official Python community for Reddit! Stay up to date with the latest news, packages, and meta information relating to the Python programming language. Just going from sd cards to USB ssd’s was a noticeable increase in speed. You are going to have the least amount of issues getting k3s running on Suse. i tried kops but api server fails everytime. 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. The only problem that I have is the input. My single piece of hardware runs Proxmox, and my k3s node is a VM running Debian. So if I didn't misunderstood this (as english is not my first language), the master is a SPOF. But if it's for a learning\play around i'd suggest looking at one of the cloud providers first. For example, we build K3s clusters with Ansible, and we have to import them into Rancher, Argo CD, etc. From this thread, it sounds like the best solution is to have several tools to launch your own cluster (k3s, kind, tilt, etc). I ran into some issue, I have installed gpu driver and plugin from official nvidia site. K3s is a stripped down version of K8s, mostly with cloud components removed, and is much more lightweight in terms of resource useage. K3S on the other hand is a standalone, production ready solution suited for both dev and prod workloads. All about small form factor PCs – decreasing size and maximizing space efficiency! I'm running K3s at home and have migrated almost all of my applications to K3s, except my Postgres/MongoDB databases (they run on a VM outside the cluster). 6 and a local Git server.

I've read some articles and watched some videos about it but I can't figure out how to design my cluster correctly. 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 choose not to PXE boot because of the overhead due to the only thing I have installed on Debian 12 is k3s. I am using k3s for many months now on one node. Or EKS Anywhere, Tanzu Community, etc. 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 I find that the easiest way to start is to just start with a few VMs. 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). 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. Using K3S allowed us to use the same deployment steps for both cloud and on premises setups. But maybe I was using it wrong. Is it really managed if you have to install your own network drivers? That is a lot to maintain, especially considering that Calico can break accross Kubernetes version, like we saw with the Reddit outage this year. 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. This community should be specialized subreddit facilitating discussion amongst individuals who have gained some ground in the software engineering world. This would then result in the HA required for us. Ive got an unmanaged docker running on alpine installed on a qemu+kvm instance. Deploy a few applications and look up any concepts that you dont understand. com with the ZFS community as well. Also: MicroOS is really nice. I'm trying to setup Kubernetes on my home server(s). Did not use the kube-prometheus directly but deployed it using the Helm chart. There's more to it but that's a general idea. By removing dispensable features (legacy, alpha, non-default, in-tree plugins) and using lightweight components (e. Uninstall k3s with the uninstallation script (let me know if you can't figure out how to do this). there’s a more lightweight solution out there: K3s It is not more lightweight. I'm also running a bunch of services (VPN, Reverse Proxy, Home Automation, ) on a single-board ARM computer with Portainer. Then reinstall it with the flags. g. k3s process includes both the containerd container runtime and kubelet. 265K subscribers in the sffpc community. Working with Kubernetes for such a long time, I'm just curious about how everyone pronounces the abbreviation k8s and k3s in different languages?

I am the technical lead of Monokle Desktop and I would be more than happy to hop on a call with you to try and figure out what the problem was and see if we can get it working for you. I installed k3s on everything and deployed a test application which worked. Reply reply maomaocake The NUC route is nice - but at over $200 a pop - that's well more than $2k large on that cluster. If you want something more serious and closer to prod: Vagrant on VirtualBox + K3S. Or check it out in the app stores Kubeadm, Kind and K3S. Installing k3s is simple and is a single binary you download and run. 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. sqlite3 instead of etcd3) they achieved a significant downsizing. 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. K3s: stale file handles on nfs volumes Hello, I setup K3s on some Raspberry Pi 3 and it almost works perfectly. You could use it with k8s (or k3s) just as well as any other distro that supports docker, as long as you want to use docker! K3OS runs more like a traditional OS. https://k3s. 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. Setup just took a few minutes. So I wiped the server and started over, this time I began creating helm charts and was using K3s. Suse releases both their linux distribution and Rancher/k3s. On each one is a controller node and a worker node. Unlike the previous two offerings, K3s can do multiple node Kubernetes cluster. rke2 is built with same supervisor logic as k3s but runs all control plane components as static pods. Before kind I used k3s but it felt more permanent and like something I needed to tend and maintain. However, due to technical limitations of SQLite, K3s currently does not support High Availability (HA), as in running multiple master nodes. 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. K3s uses less memory, and is a single process (you don't even need to install kubectl). I want to create my own little Kubernetes cluster on Hetzner Cloud using 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 K3s is a binary that can run on technically any Linux OS, and configured to your specific needs.

What I need to mount as volume and what inside container. For immediate help and problem solving, please join us at https://discourse. These all are the benefits I see after using 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. The big difference is that K3S made the choices for you and put it in a single binary. The kernel comes from ubuntu 18. In a way, K3S bundles way more things than a standard vanilla kubeadm install, such as ingress and CNI. This results in a single binary with a size of around 60 MB. Kubernetes is pretty easy to use but has a high learning curve. We are Using k3s on our edge app, and it is use as production. It's installable from a 40 MB binary. 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. I'm new into Kubernetes and just starting out. No, it is not a fork of Kubernetes. Eventually they both run k8s it’s just the packaging of how the distro is delivered. Do you guys have some links or articles I can checkout. Oh, and even though it's smaller and lighter, it still passes all the K8s conformance tests, so works 100% identical. 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. 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 still deciding how things will be laid out, but I current have 3 proxmox servers . K3S is legit. 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). But other options are also available. I'll give you a quick rundown of the main concepts I've covered in them. Note: I don’t work for/with anybody that’s affiliated with Rancher, k3s, or k3d. xyz. Rock solid, easy to use and it's a time saver. But if a pod crashes or gets rescheduled I sometimes get stale file handle errors and the container needs to be manually restarted. 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. We are using K3S in production for many of our clients. Welcome to Reddit's own amateur (ham) radio club. --- 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. A better test would be to have two nodes, the first the controller running the db, api server, etc and the second just the worker node components, kubelet, network, etc. Cluster Management with Rancher: Utilizing Rancher to deploy and manage all Kubernetes (k8s) and K3s clusters using the Packer template. I use K3S heavily in prod on my resource constricted clusters. If you have questions or are new to Python use r/learnpython Hi, since it does not feel to me that google is the best source for finding the current top 3 GUIs for Kubernetes I thought, why not asking here.

I have been using a simple Fiio K3 for a few years, and it has served me well till now. What is the "best" option for a single-node cluster? I am going to set up a new server that I plan to host a Minecraft server among other things. My next k3s node will likely be fedora but when I add the Pi, one will be raspbian. 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. 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. 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. 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. 04, and the user-space is repackaged from alpine. 5mm port on the K3, they sound more than loud enough at max with the gain on. S3 and CloudFront are designed by people who have expertise in writing highly scalable, available, fast, and redundant applications. 212 votes, 24 comments. Wiping k3s off the OS is very easy and pretty much brings the OS back to its stock state. However, most failover setups actually require a minimum of 3 nodes so that they can have a quorum. k3s is very geared towards "as thin of a distribution as possible, for running stuff on the edge". S3 and CloudFront is the right solution here given you have those tools available. 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 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. Yes but there's other ways to do it with PXE booting and netboot. I think Rancher has another storage solution which is compatible with K3s. disable built in stuff [during k3s deployment] which I later replace with nginx ingress [instead of traefik] and metallb [instead of servicelb]: curl -sfL https://get. I'm struggling however with terminology, ingress controllers and honestly with a lot of examples pulling in things that aren't explained very well -- such as manifests and service files. But honestly you can just use straight k8s manifests in k3s (there is a special folder where k3s loads manifest files automagically). I'm learning K3s at home on a single-node cluster (I don't need redundancy, yet). 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). Note: whatever you do, don’t use ZFS. There is more options for cni with rke2. For management I’ve used ArgoCD (it’s a management/gitops tool) since I use it at work. 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. If you have something to teach others post here. But I'm torn between hosting it directly as a TrueNAS App (using the built-in k3s stack) and using docker-compose, as is recommended by the Immich devs. This sub has no official connection to the Discord server, nor does this sub have any official endorsement or official relationship with BMW themselves. That Solr Operator works fine on Azure AKS, Amazon EKS, podman-with-kind on this mac, podman-with-minikube on this mac. It seems to be lightweight than docker. Personally I think k3s has a lot going for it, I really need to start verifying some of my applications/workloads against it. 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. CNI is Cilium (love it) and PortWorx is used for distributed storage. But if you need a multi-node dev cluster I suggest Kind as it is faster. If you don't need as much horsepower, you might consider a Raspberry Pi cluster with K8s/K3s. I have a couple of dev clusters running this by-product of rancher/rke. 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. I just really got a LOT of value out of k3d + k3s as a beginner. I used K3s to run a Kubernetes cluster on my custom server build with a Ryzen 7 3700X, 32GB RAM and an RX 560 for hardware encoding. The conclusion here seems fundamentally flawed. gvyhkzi qbvgj brahyg hxnxfejy eucnndr hijetd wos tsuadtlx ahh euu gfhoceo jktjzr cpn yzidew vnrchj
