kraft run

kraft run [FLAGS] PROJECT|PACKAGE|BINARY -- [APP ARGS]

Run a built target in the current working directory project:
$ kraft run

Run a specific target from a multi-target project at the provided project directory:
$ kraft run -t TARGET path/to/project

Run a specific kernel binary:
$ kraft run --arch x86_64 --plat qemu path/to/kernel-x86_64-qemu

Run a specific kernel binary with 1000 megabytes of memory:
$ kraft run --arch x86_64 --plat qemu --memory 1G path/to/kernel-x86_64-qemu

Run a specific kernel binary with 1024 megabytes of memory:
$ kraft run --arch x86_64 --plat qemu --memory 1Gi path/to/kernel-x86_64-qemu

Run an OCI-compatible unikernel, mapping port 8080 on the host to port 80 in the unikernel:
$ kraft run -p 8080:80 unikraft.org/nginx:latest

Attach the unikernel to an existing network kraft0:
$ kraft run --network kraft0

Run a Linux userspace binary in POSIX-/binary-compatibility mode:
$ kraft run a.out

Supply an initramfs CPIO archive file to the unikernel for its rootfs:
$ kraft run --rootfs ./initramfs.cpio

Supply a path which is dynamically serialized into an initramfs CPIO archive:
$ kraft run --rootfs ./path/to/rootfs

Mount a bi-directional path from on the host to the unikernel mapped to /dir:
$ kraft run -v ./path/to/dir:/dir

Supply a read-only root file system at / via initramfs CPIO archive and mount a bi-directional volume at /dir:
$ kraft run --rootfs ./initramfs.cpio --volume ./path/to/dir:/dir

Customize the default content directory of the official Unikraft NGINX OCI-compatible unikernel and map port 8080 to localhost:
$ kraft run -v ./path/to/html:/nginx/html -p 8080:80 unikraft.org/nginx:latest
