SD card image for Raspberry Pi with Docker: HypriotOS
This repo builds the SD card image with HypriotOS for the Raspberry Pi 1, 2, 3, 4 and Zero. You can find released versions of the SD card image here in the GitHub releases page. To build this SD card image we have to take the files for the root filesystem from os-rootfs.
