Multi-Target Static Rust Project from Git Repo

Using this Dockerfile one can build a statically linked Rust project from a Git repo (provided it has minimal external dependencies) in an Ubuntu (latest) container targeting both ARMv7 and i686.

Container Build

$ podman build -t crossbuild-multi -f multi-target-static-git

Build Example

This assumes PROJECT_DIR is set to the path to which this repo was cloned.

The project built in this example is my connchk crate.

$ mkdir ~/build_dir
$ cp ${PROJECT_DIR}/examples/ ~/build_dir/
$ podman run --rm -it -e GIT_REPO="" \
	-e BIN_NAME="connchk" \
	-v "${HOME}/build_dir:/opt/build:z \
	crossbuild-multi:latest \
