This repo contains a collection of scripts helping you to set up Ubuntu Core 14.04.3 / Debian 8 Jessie and Docker on your ARMv7 device within less than five minutes. Each subdirectory has this collection of scripts:

• ubuntu-core-00.sh: set up u-boot, partition & format the boot device, do the correct mounts
• ubuntu-core-01.sh: unpacks the Ubuntu Core userland, prepare and jump into the chroot environment
• ubuntu-core-02.sh: (invoked by ubuntu-core-01.sh) customize the userland, install gcc-5, install the kernel image
• ubuntu-docker-00.sh: setup docker in the newly booted environment (doesn't work in chroot)

• debian-00.sh: set up u-boot, partition & format the boot device, do the correct mounts
• debian-01.sh: debootstraps the Debian userland, prepare and jump into the chroot environment
• debian-02.sh: (invoked by ubuntu-core-01.sh) customize the userland, install gcc-5, install the kernel image
• debian-docker-00.sh: setup docker in the newly booted environment (doesn't work in chroot)

Please choose the correct device (e.g. SD card reader) to be taken in ubuntu-core-00.sh / debian-00.sh.
