cargo rumpbake

A small wrapper around cargo build and rumpbake for generating rumprun unikernel images from binary crates.


The prefered way to use this build and install this subcommand is by building the rust package from rumprun-packages.


Make sure rumprun's app-tools is in your $PATH. A crate named "hello" with a single binary target can be baked into a rumprun unikernel as follows.

cargo rumpbake hw_virtio

Which is roughtly equivalent to the following:

cargo build --target x86_64-rumprun-netbsd
rumpbake hw_virtio hello.img ./target/x86_64-rumprun-netbsd/debug/hello

The name of the generated image can be set using the --output flag. Use the rumprun command line utility to execute the generated image:

rumprun qemu -i hello.img
