Bootstrap a minimal debian for olinuxino-a20-lime2
Thanks to lukas2511 for quick bootstrap.
Build docker image
sudo docker pull debian:stable
git clone https://github.com/bleuchtang/olinuxino-a20-lime2
cd olinuxino-a20-lime2 && sudo docker build -t debian/olinux .
Build minimal arm debootstrap
We cannot perform a debootstrap in dockerfile because dockerfile doesn't accept privileged mode. For more details see docker issue
sudo docker run --privileged -i -t -v $(pwd)/olinux/:/olinux/ debian/olinux sh ./olinux/create_arm_debootstrap.sh
Build sunxi kernel and boot files
You shoud have both debootstrap and sunxi directories in olinux/
sudo docker run --privileged -i -t -v $(pwd)/olinux/:/olinux/ debian/olinux sh ./olinux/create_sunxi_boot_files.sh
Install on a sd card

TODO
- change Install on a sd card to a script ?
Some links:
You probably want to Build your own docker image
- Because it's quick and easy; tutorial here
- Because you shoudn't trust regitry images; demonstration here
