Worker image for GitHub Actions custom runner

Copyright (c) 2020-2021 Antmicro

This project contains the scripts and configuration files for building an image used by Antmicro's GitHub Actions runner.

Usage

Build the Buildroot-based image first by running cd buildroot && make BR2_EXTERNAL=../overlay/ scalenode_gcp_defconfig && make.

Then, run ./make_gcp_image.sh. This will prepare a disk with grub-legacy as MBR bootloader with configuration and kernel image on a 200MB FAT partition.

Next run ./upload_gcp_image $GCP_PROJECT $GCP_BUCKET. The tar archive created in the previous step will be uploaded to a Google Cloud Storage bucket and a ready-to-use image will be created. This step is described more in-depth in the Google Cloud documentation page on importing images.

Testing

It is possible to test the image locally by running the ./run_qemu.sh script.

The SSH server will be accessible at port 9022 on localhost.
