Introducing resinOS: An Operating System Tailored for Containers and Built for the Embedded World
summary
resinOS packages full Docker userlands on constrained devices, running in production for ~2.5 years across thousands of devices and supporting ~22 boards. It builds with Yocto, runs builds inside Docker, uses dual A/B root partitions and a separate data partition so containers never mutate the read‑only root, and updates by pulling Docker images (AUFS storage, back‑ported Docker patches). Runtime uses systemd, NetworkManager/ModemManager, dnsmasq, journald (8 MB in‑RAM buffer) and seccomp. Developer tools include resin-device-toolbox and resin push live sync; QEMU and hardware harnesses provide CI.
