fc-kernels

Overview

This project automates the building of custom Firecracker. 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 Kernels

1. Configure firecracker versions:

   • Edit firecracker_versions.txt to specify which kernel versions to build (one per line, e.g., <last_tag-prelease>-<first-8-letters-of-the-specific-commit>).

2. Build:

   make build
   # or directly
   ./build.sh

   The built kernels will be placed in builds/vmlinux-<version>/vmlinux.bin.

Development Workflow

• On every push, GitHub Actions will automatically build the kernels and save it as an artifact.
