Been a proper pain in the ass (edit: but also fun and useful) to make though because of a learning curve. I guess the benefits over GKE, EKS (as a managed K3s cloud service) is speed and cost, as it's quicker to install and uses less RAM too. Also, a good example is the Civo managed K3s service, as it also abstracts away the control plane and provides uptime guarantee comparable to hyperscalers. Aug 8, 2024 · k0s and k3s are both CNCF-certified k8s distributions, and meet all the benchmarks/requirements for standard k8s clusters. Conclusion What's your reason for using openshift vs k3s/k3sup? I've found that k3sup compresses the deployment process, from wiping the incoming node to scheduling pods onto the node, into 2 steps.

Oh, and even though it's smaller and lighter, it still passes all the K8s conformance tests, so works 100% identical. We're using microk8s but did also consider k3s. I use K3S heavily in prod on my resource constricted clusters. 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). Then most of the other stuff got disabled in favor of alternatives or newer versions. I am also pretty sure that it wasn’t K2d. And storage provisioners. The UX of k0s is only a small portion of what Talos is. Now, a little about the OS to point out where it adds more than just an easy way to run Kubernetes. I’m using an NFS (by utilizing the Kubernetes NFS Subdir provisioner). Do I just get to point my k3s config at Amazon and it works? I use k3s as my petproject lab on Hetzner cloud Using terraform for provision network, firewall, servers and cloudflare records and ansible to provision etcd3 and k3s Master nodes: CPX11 x 3 for HA Working perfectly I recommend Talos Linux, easy to install, You can run it in docker or vm locally on your host.
