Okay, I think I got it. Being that it wants to dynamically link, its going to be looking for the dynamic libs in whatever filesystem its running in. This Dockerfile:

  • Adds the glibc-dev package
  • Adds clang lld and gcc from Alpine apk repos
  • Installs the Rust target with rustup
  • Modifies the RUSTFLAGS paths:
    • ENV RUSTFLAGS="${RUSTFLAGS} -C link-arg=-L/usr/glibc-compat/lib"
    • ENV RUSTFLAGS="${RUSTFLAGS} -C link-arg=-Wl,--dynamic-linker=/lib64/ld-linux-x86-64.so.2"
  • Copies out the right things
  • copies shared libs to the package container
  • copies the dynamically linked binary to the package container
