Developing bootupd

Currently the focus is Fedora CoreOS.

You can use the normal Rust tools to build and run the unit tests:

cargo build and cargo test

For real e2e testing, use e.g.

export COSA_DIR=/path/to/fcos
cosa build-fast
kola run -E (pwd) --qemu-image fastbuild-fedora-coreos-bootupd-qemu.qcow2  --qemu-firmware uefi ext.bootupd

See also the coreos-assembler docs.

Building With Containers

Many folks use a pet container or toolbox to do development on immutable, partially mutabable, or non-Linux OS's. For those who don't use a pet/toolbox and you'd prefer not to modify your host system for development you can use the build-in-container make target to execute building inside a container.

$ make build-in-container
podman build -t bootupd-build -f Dockerfile.build
