Edge Computing using K3s on Raspberry Pi
Talkat KubeCon + CloudNativeCon North America 2021 · on Friday, 2021-10-15· at 14:30· Petree Hall C + Online·
summary
Claims a reproducible, 3-node HA K3s cluster on Raspberry Pi 4 (2/4/8GB) using Ubuntu SD images, Ansible for bootstrap, and the ketchup installer to get kubeconfig. Cluster hits Kubernetes v1.21.3 with containerd 1.4.8 after rolling upgrades driven by a system-upgrade-controller CRD so both k8s and OS updates run through the Kubernetes API. Over‑the‑top components include external-dns and cert-manager; roadmap notes adding kube‑vip for API failover and Argo CD arm64 support. Repo: github.com/jeffspahr/k3s-on-pi.
