(no problem) As far as I know microk8s is standalone and only needs 1 node. For my dev usecase, i always go for k3s on my host machine since its just pure kubernetes without the cloud provider support (which you can add yourself in production). Turns out that node is also the master and k3s-server process is destroying the local cpu: I think I may try an A/B test with another rke cluster to see if it's any better. I've started with microk8s. Let’s take a look at Microk8s vs k3s and discover the main differences between these two options, focusing on various aspects like memory usage, high availability, and k3s and microk8s compatibility.

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. My single piece of hardware runs Proxmox, and my k3s node is a VM running Debian.

In recent versions it seems to be production ready and the add-ons work well but we're open to switching. This analysis evaluates four prominent options—k3s, MicroK8s, Minikube, and Docker Swarm—through the lens of production readiness, operational complexity, and cost efficiency. Rancher just cleaned up a lot of the deprecated/alpha APIs and cloud provider resources. If you need a bare metal prod deployment - go with My company originally explored IoT solutions from both Google and AWS for our software however, I recently read that both MicroK8s and K3s are potential candidates for IoT fleets.

I know you mentioned k3s but I definitely recommend Ubuntu + microk8s. With microk8s the oversemplification and lack of more advanced documentation was the main complaint. Other than that, they should both be API-compatible with full k8s, so both should be equivalent for beginners. I don't see a compelling reason to move to k3s from k0s, or to k0s from k3s. Personally I'm leaning toward a simple git (or rather, pijul, if it works out) + kustomize model for basic deployment/config, and operators for more advanced policy- or Sep 4, 2020 · Hello @ktsakalozos. oup rgiru kzgumz jogew xclf eiufn vwysgih wogx bde jkzb pkxp gqmhy bciwlrn rptj aca
