Docker files to build an Open System Firmware image based on coreboot and LinuxBoot.
Just run either docker or podman:
podman build -t insomniacslk/osf-build -f Dockerfile .
podman run --rm -it insomniacslk/osf-build
The last command will run QEmu in nographics mode. Remember that you can
terminate QEmu with ctrl-a x.
You can copy the output files with a command like this:
podman run --rm -it --mount type=bind,source="${PWD}"/output,target=/home/circleci/output insomniacslk/osf-build sudo cp coreboot.rom disk.img output/
This will create an output directory on the host system, containing
coreboot.rom and disk.img.
This is mostly equivalent to the process described in the chapter LinuxBoot using coreboot, u-root and systemboot of the LinuxBoot book.
