ARG CARGO_BUILD_TARGET=x86_64-unknown-linux-musl # We build the Lemmy binary for amd64 and arm64 in individual stages using the blackdex/rust-musl image (github.com/blackdex/rust-musl).
# This image uses musl-cross-make (github.com/richfelker/musl-cross-make) to build a musl cross compilation toolchain for the target
# architecture. It also includes pre-built static libraries such as libpq. These libraries can improve the compile time and eliminate
# the requirement for extra dependencies in the final image.
#
# During each build stage, we use the blackdex/rust-musl openssl 3 images and configure PQ_LIB_DIR=/usr/local/musl/pq15/lib to use
# libpq v15. We also ensure the installation of the Rust toolchain corresponding to the target architecture using:
# `rustup target add $TARGET-unknown-linux-musl`.
