summary
MicroShift is a stripped-down Kubernetes that runs on 2 cores, 2 GB RAM devices and even ~16 GB SD cards by starting from a minimal distro and adding only networking, ingress and storage. It uses ovnk CNI after footprint and dynamic-IP testing, a CSI based on a Topo/LVM variant for enforced quotas and snapshots, and OSTree image embedding so container images are baked into the OS for air‑gap boots. Atomic OS updates and rollbacks rely on OSTree snapshots; Kubernetes rollback is still a work in progress.
