kernel-build-containers

This project provides Docker containers for building the Linux kernel (or other software) with many different compilers.

License: GPL-3.0.

It’s very useful for testing gcc-plugins for the Linux kernel, for example. Goodbye headache!

How to build container images

Get help:

$ python3 manage_images.py -h
usage: manage_images.py [-h] [-l] [-b compiler] [-q] [-r]

Manage the images for kernel-build-containers

options:
  -h, --help            show this help message and exit
  -l, --list            show the container images and their IDs
  -b compiler, --build compiler
                        build a container image providing clang-5 / clang-6 / clang-7 /
                        clang-8 / clang-9 / clang-10 / clang-11 / clang-12 / clang-13 /
                        clang-14 / clang-15 / clang-16 / clang-17 /
                        gcc-4.9 / gcc-5 / gcc-6 / gcc-7 / gcc-8 / gcc-9 / gcc-10 / gcc-11 /
                        gcc-12 / gcc-13 / gcc-14 / all (use "all" for building all images)
  -q, --quiet           suppress the container image build output (for using with --build)
  -r, --remove          remove all created images

Build a single container image:

$ python3 manage_images.py -b gcc-12

Build a container image quietly:

$ python3 manage_images.py -b clang-11 -q

List container images:

$ python3 manage_images.py -l
We need "sudo" for working with containers

How to run a container

Get help:

$ bash start_container.sh
Hey, we gonna use sudo for running docker
usage: start_container.sh compiler src_dir out_dir [-n] [-e VAR] [-h] [-v] [-- cmd with args]
  -n    launch container in non-interactive mode
  -e    add environment variable in the container (may be used multiple times)
  -h    print this help
  -v    enable debug output

  If cmd is empty, we will start an interactive bash in the container.

Run interactive bash in the container:

$ bash start_container.sh gcc-12 ~/linux-stable/linux-stable/ ~/linux-stable/build_out/
Hey, we gonna use sudo for running docker

Mount build output directory "/home/a13x/linux-stable/build_out/" at "/home/a13x/out"
Gonna run bash

To run a command as administrator (user "root"), use "sudo <command>".
See "man sudo_root" for details.

Notes for developers

If you change manage_images.py, please run the test:

$ bash test_image_mgmt.sh

The code coverage will be stored in htmlcov/index.html.

Have fun!
