libcnb-cargo  

A Cargo command for managing buildpacks written with libcnb.rs.

Installation

$ cargo install libcnb-cargo

Usage

Currently, there is only one sub-command: package. It allows users to package their Rust buildpack in a spec-compliant manner and helps with cross-compilation. Using it is fairly simple, run cargo libcnb package inside the buildpack's project directory:

$ cargo libcnb package
INFO - Reading buildpack metadata...
INFO - Found buildpack libcnb-examples/my-buildpack with version 0.1.0.
INFO - Determining automatic cross-compile settings...
INFO - Building binaries (x86_64-unknown-linux-musl)...
# Omitting compilation output...
    Finished dev [unoptimized + debuginfo] target(s) in 4.29s
INFO - Writing buildpack directory...
INFO - Successfully wrote buildpack directory: target/buildpack/debug/libcnb-examples_my-buildpack (3.26 MiB)
INFO - Packaging successfully finished!
INFO - Hint: To test your buildpack locally with pack, run: pack build my-image --buildpack target/buildpack/debug/libcnb-examples_my-buildpack --path /path/to/application
