A plain docker environment for building static binaries compiled with rust and linked against musl instead of glibc. Built nightly on travis.
This is only useful if you require external C dependencies, because otherwise you could do rustup target add x86_64-unknown-linux-musl.
This container comes with a bunch of statically compiled C libraries using musl-gcc so that we can statically link against these as well.
If you already have rustup installed on the machine that should compile, you might consider cross as a more general solution for cross compiling rust binaries.
Usage
Pull and run from a rust project root:
docker pull clux/muslrust
docker run -v $PWD:/volume --rm -t clux/muslrust cargo build
You should have a static executable in the target folder:
ldd target/x86_64-unknown-linux-musl/debug/EXECUTABLE
not a dynamic executable
From there on, you can include it in a blank docker image (because everything you need is included in the binary) and perhaps end up with a 5MB docker blog image.
This post is intended as a tour of various techniques (not necessarily all practical) of reducing program size, but if you demand some conclusion, the pragmatic takeaway is that:
Compile with --release.
Before distribution, enable LTO and strip the binary.
If your program is not memory-intensive, use the system allocator (assuming nightly).
You may be able to use the optimization level s/z in the future as well.
I didn’t mention this because it doesn’t improve such a small program, but you can also try UPX and other executable compressors if you are working with a much larger application.Meet Rocket.
