This Docker image provides an environment for cross-compiling Linux kernel packages for both arm64 and amd64 architectures.

• Docker installed on your system
• Sufficient disk space (at least 20GB recommended)
• Sufficient RAM (at least 8GB recommended)

docker build -t kernel-builder .

docker run --rm -v $(pwd)/output:/output -eARCH="amd64" kernel-builder

docker run --rm -v $(pwd)/output:/output -eARCH="arm64" kernel-builder

You can customize the build by setting environment variables:

docker run --rm \
  -v $(pwd)/output:/output \
  -e KERNEL_TAG=v6.8 \
  -e KERNEL_SOURCE=https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git \
  kernel-builder arm64

The built Debian packages will be available in the output directory on your host system. The packages include:

• linux-image-*.deb: The kernel image package
• linux-headers-*.deb: The kernel headers package
• linux-libc-dev-*.deb: The kernel development package

• The build process may take several hours depending on your system's resources
• Make sure you have enough disk space in the output directory
• You can provide your own config by supplying a file in the input directory named config-${KERNEL_TAG}-${ARCH}
  • The supplied config file will be olddefconfig'd because we don't trust you
• The build uses the default kernel configuration (defconfig)
• Patches found in /input/patches will be applied to the kernel source before configuration
  • The /input/patches/all subdirectory will be processed for all build tags
  • For patches intended for specific build tags use /input/patches/${KERNEL_TAG}
  • Files directly in /input/patches, or files beginning with a period will not be processed
