Buildkite for GCE

This repo contains everything you need use buildkite on GCE.

Use docker to build the image

1. Make sure you download and place alpine-virt-3.8.0-x86_64.iso in this folder
2. Run docker run --rm --volume $(pwd):/build justincormack/alpine-qemu /build/docker-entrypoint.sh in this folder
3. Get a cup of coffee
4. disk.raw.tar.gz should be created

Without docker

1. Make sure you download and place alpine-virt-3.8.0-x86_64.iso in this folder
2. Make sure you have installed expect qemu and mkisofs
3. run create-vm.exp
4. Get a cup of coffee
5. disk.raw.tar.gz should be created

Then upload disk.raw.tar.gz to your google bucket (and import it to gce afterwards)
