I'm also looking at swarm and k3s for my home network as I have a lot of apps ( singleton, no HA ) running in containers now. rke2 is built with same supervisor logic as k3s but runs all control plane components as static pods. No etcd, only postgres, I don't want that kind of useless write pressure on my node SSDs. So yeah, it is just your opinion and no facts. For local development of an application (requiring multiple services), looking for opinions on current kind vs minikube vs docker-compose. I've been working on a tool to help dive into Minikube/KIND/k3s/etc logs for tests running on Github and would like some feedback. Nginx for today is kind of standard. Then most of the other stuff got disabled in favor of alternatives or newer versions. R. While k3s and k0s showed by a small amount the highest control plane throughput and MicroShift showed the highest data plane throughput, usability, security, and maintainability are additional factors that drive the decision for an appropriate distribution. and god bless k3d) is orchestrating a few different pods, including nginx, my gf’s telnet BBS, and a containerized Not only is k3s great for learning Kubernetes, it can and should be used in a lot of production scenarios. Strangely, the worker node seems to have trouble resolving DNS. How much it will affect the sound quality from my onboard audio by using external DAC/AMP such as FIIO K3S when using my headphone? Is FIIO K3S is worth to buy compared to other DAC/AMP (like the FIIO E10K model)? That is a pretty decent list.

The only difference is k3s is a single-binary distribution. 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. I can spin up a cluster in 1 command and tear it down just as easily. If you really want to go ultra-cheap and/or have maximum node access, and have the spare compute capacity laying around (it doesn't take much -- if you just replaced your laptop recently and still have the old one, that's probably plenty), k3s (the distribution Civo uses for their managed clusters) is easy to get up and running yourself in a Maybe stand up k3s single-node to start with; it should only be a single command. kind.
