ubuntu-kernel-build

A Docker container for building an Ubuntu kernel with arbitrary patches, config flags, and a tag.

Example

A simple kernel build can be run like so:

sudo install --directory -o 1000 -g 1000 ~/kbuild
sudo docker run -it --rm -v ~/kbuild:/data \
    naftulikay/ubuntu-kernel-build

The end result will be a series of Debian kernel packages in the ~/kbuild directory.

A more advanced build with patches and building lowlatency, cloud, and generic kernel packages:

sudo docker run -it --rm -v ~/kbuild:/data -v ~/patches:/patches \
    -e BUILD_TYPE=full naftulikay/ubuntu-kernel-build

Environment Variables

KERNEL_MAJOR

The major kernel version to build, by default 4.4.0.

BUILD_TAG

The tag appended to the package version to make the package unique, defaults to hardcore for obvious reasons.

BUILD_TYPE

The type of kernel build to run, either fast (default), full, or custom.

If custom, BUILD_CMD must be specified.

BUILD_CMD

If BUILD_TYPE is set to custom, this must be specified as arguments to fakeroot debian/rules.

Volumes

/data

This will be the directory where the kernel is built. It should be owned by a user with a UID of 1000.

/patches

This is a directory containing patch files to apply against the kernel sources before building.
