fc-versions

Overview

This project automates the building of custom Firecracker versions. It supports building specific firecracker versions and uploading the resulting binaries to a Google Cloud Storage (GCS) bucket.

Prerequisites

• Linux environment (for building firecracker)

Building Firecrackers

The firecracker_versions.txt file specifies which versions to build:

• Edit firecracker_versions.txt to specify firecracker versions (one per line)
• Versions can be tags (e.g., v1.10.1) or tag with shorthash (e.g., v1.12.1_abcdef12)
• On every push, GitHub Actions will automatically:
  1. Parse versions from firecracker_versions.txt and resolve commit hashes
  2. Build each version in parallel
  3. Check CI status for each version
  4. Upload successful builds to GCS and create GitHub releases (on main branch)

Scripts

• build.sh <version> <hash> <version_name> - Builds a single Firecracker version
• scripts/parse-versions-with-hash.sh - Parses versions and resolves commit hashes
• scripts/check-fc-ci.sh <versions_json> - Checks CI status for parsed versions
