K3s Lightweight Kubernetes
Guide for deploying and managing K3s lightweight Kubernetes clusters. Covers single-node and multi-node installation, HA with embedded etcd or external databases, networking (Flannel, ServiceLB, MetalLB, custom CNI), storage (local-path, Longhorn), HelmChart CRD and auto-deploy manifests, air-gap installation, edge/IoT patterns, CIS security hardening, secrets encryption, system-upgrade-controller, and Rancher multi-cluster management. Use for K3s-specific tasks; do not use for full upstream Kubernetes (kubeadm/kops), managed cloud Kubernetes (EKS/GKE/AKS), or alternative lightweight distros (K0s, MicroK8s).
