⁠How to Create your own Official from SCRATCH

I've noticed that a few people have created these, but no one tells you HOW they did it. And after all, are you really going to run some random person's "trust-me-I-am-not-evil" image?

So, here's how to build one yourself:

1. Boot into an ARM OS with Docker OS (ex: Hypriot would be the best, or Raspbian with Hypriot's package, or your own)

2. Pull the OFFICIAL "mkimage-alpine.sh" from Docker's GITHUB:

wget https://raw.githubusercontent.com/docker/docker/master/contrib/mkimage-alpine.sh

1. Export the correct ARCH (this is because Alpine's Repo directory is called "armhf", and run the script with -s to save the rootfs:

export ARCH=armhf; ./mkimage-alpine.sh -s

1. Uncompress the the rootfs.tar.xz:

xz -d rootfs.tar.xz

1. Create a build folder, move the rootfs.tar, and create a Dockerfile:

mkdir container
mv rootfs.tar container/.
cd container

1. Inside the "container" folder, create a Dockerfile looks like this:

FROM scratch
ADD rootfs.tar /
CMD ["/bin/sh"]

1. Build it (while IN the 'container' folder):

docker build --force-rm=true --no-cache=true --rm=true -t 'dockerhubusername/armhf-alpine' .

That's it. Now you can TRUST OR build your own! :)
