However, now I have the hw resources to waste memory and whatever else I wish and I'd like to do it for educational purposes. However, when I execute a command I get "error: no Auth Provider found for name "oidc"". Doing high availability with just VMs in a small cluster can be pretty wasteful if you're running big VMs with a lot of containers because you need enough capacity on any given node to In a highly available K3s Cluster, is a load balancer needed or can you utilize the Traefik Ingress Controller and load balancer (Klipper) that’s included in the install? Archived post. Unlike the previous two offerings, K3s can do multiple node Kubernetes cluster. com with the ZFS community as well. We are using K3S in production for many of our clients. RKE2 is more for your traditional kubernetes installation where scalability is more of the goal. 28 added beta support for it. Hi, so I'm trying to set up a single node k3s cluster on Oracle's free arm instance and I'm facing some problems when trying to install MetalLB (trying to set up subdomains on a single host managed by the ingress). Over the weekend in my lab I was playing with OIDC as a means of authenticating to the cluster without using the default root account. There is more options for cni with rke2. I think Rancher has another storage solution which is compatible with K3s. I need some guidance on how to configure --cluster-cidr (Pod IPs) and --service-cidr (Services IPs) explained here. k3s. I'm new into Kubernetes and just starting out. We're actually about to release a native K8s authentication method sometime this week — this would solve the chicken and egg ("secret zero") problem that you've mentioned here using K8s service account tokens.

So far, I have setup K3s itself, Helm, Flux, and a few applications (all deployed via Flux) that don't require storage. 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. In a way, K3S bundles way more things than a standard vanilla kubeadm install, such as ingress and CNI. I use k3s for this usecase, but there is quite a bit of overhead (10-20% CPU maybe? and like 300-400 MB of ram) just from running k3s itself, even without traefik and local-path-provisioner that it installs by default.

Reply reply I'm learning K3s at home on a single-node cluster (I don't need redundancy, yet). My initial plan was to build it around a couple of Raspberry Pi's, but I wanted the setup to be reproducible and easy to reprovision, meaning more IaC and less direct interaction with the nodes. I’d love to hear pros/cons from others. If you want something more serious and closer to prod: Vagrant on VirtualBox + K3S. “designed for production workloads in unattended, resource-constrained, remote locations or inside IoT appliances.
