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

Run the release.yml GitHub Actions workflow (Actions → Manual Build & Release → Run workflow) to build and upload Firecracker binaries.

Workflow Inputs

• tag (required): Firecracker version tag (e.g., v1.14.1)
• commit_hash (optional): Full commit hash to build. Defaults to the tag's commit.
• build_amd64 (optional): Build for amd64 architecture. Default: true
• build_arm64 (optional): Build for arm64 architecture. Default: true

What it does

1. Validates inputs and resolves the commit hash
2. Checks GCS and GitHub releases for existing artifacts
3. Builds missing architectures in parallel
4. Uploads binaries to GCS and creates a GitHub release

Scripts

• build.sh <tag> <commit_hash> <version_name> [arch] - Builds a single Firecracker binary
