Instructions for Bootable images / Auto-installing ISO

[jsundqvist]

The information on https://rancher.github.io/os2/customizing/#bootable-images is outdated and broken.

Here's what I came up with to produce an ISO:

#!/bin/bash

set -e

LATEST=$(curl 'https://quay.io/api/v1/repository/costoolkit/os2/tag/?limit=1' -H 'accept: application/json' | jq -r '.tags[0].name')
curl -o ros-image-build "https://raw.githubusercontent.com/rancher-sandbox/os2/master/ros-image-build"

export DOCKER_BUILDKIT=1 # to make build/output.iso actually appear
export BUILDKIT_PROGRESS=plain
bash ros-image-build "quay.io/costoolkit/os2:$LATEST" iso #config.yaml

mv build/output.iso "rancher-os_$LATEST.iso"

Some notes:

• Nothing has happened in this repo since Jan 19, but https://github.com/rancher-sandbox/os2 has active development. This is unfortunate since this repo is where you end up when coming from Google.
• Images are not published to Docker Hub, but quay.io
• The docker build option -o build/ does nothing unless DOCKER_BUILDKIT=1 is set, this could/should be incorporated into ros-image-build

Leaving this here to hopefully spare others of the software forensics.
