KRAFT-BUILD(1)

💅 NAME 💅

kraft-build — Configure and build Unikraft unikernels. Bestie, this is straight from the KraftKit Manual — aka the KraftKit CLI(1) page — and it's giving very main-character build energy ✨

🚀 SYNOPSIS 🚀

kraft build [FLAGS] [SUBCOMMAND|DIR]

okay so that's the shape of it: flags are optional, then either a subcommand or a directory. Slay.

🛠️ DESCRIPTION 🛠️

Build a Unikraft unikernel. Literally that's the assignment, no cap.

The default behaviour of kraft build is to build a project. Given no arguments, you will be guided through interactive mode — it holds your hand a little and that's iconic 🫶

✨ OPTIONS ✨

• --all[=false] — Build all targets. All of them, bestie.
• -m, --arch="" — Filter the creation of the build by architecture of known targets (x86_64/arm64/arm).
• --build-log="" — Use the specified file to save the output from the build.
• -c, --config="" — Override the path to the KConfig .config file.
• --dbg[=false] — Build the debuggable (symbolic) kernel image instead of the stripped image.
• -e, --env=[] — Set environment variables to be built in the unikernel.
• --force-pull[=false] — Force pulling packages before building.
• -h, --help[=false] — help for build.
• -j, --jobs=0 — Allow N jobs at once.
• --keep-file-owners[=false] — Keep file owners (user:group) in the rootfs (false sets 'root:root').
• -k, --kernel="" — Set the output path of the built kernel image.
• -K, --kraftfile="" — Set an alternative path of the Kraftfile.
• -F, --no-cache[=false] — Force a rebuild even if existing intermediate artifacts already exist.
• --no-configure[=false] — Do not run Unikraft's configure step before building.
• --no-fast[=false] — Do not use maximum parallelization when performing the build.
• --no-fetch[=false] — Do not run Unikraft's fetch step before building.
• --no-rootfs[=false] — Do not build the root file system (initramfs).
• --no-update[=false] — Do not update package index before running the build.
• -o, --output="" — Set the output directory for the build artifacts.
• -p, --plat="" — Filter the creation of the build by platform of known targets (fc/qemu/xen).
• --print-stats[=false] — Print build statistics.
• --rootfs="" — Specify a path to use as root file system (can be volume or initramfs).
• --rootfs-type="cpio" — Set the type of the format of the rootfs (cpio/erofs).
• -t, --target="" — Build a particular known target.
• -T, --toolchain=[] — Override toolchain variables for this build (e.g. CC=clang LD=ld.lld).
• --toolchain-profile="" — Use a pre-configured toolchain profile.
• -C, --validate[=false] — Validate KConfig options against known symbols.
