# Dockerfile for building static musl-linked RustNet binary
|
|
#
|
|
# Usage (with eBPF - default, recommended):
|
|
# docker build -f Dockerfile.static -t rustnet-static .
|
|
# docker run --rm -v $(pwd)/dist:/dist rustnet-static cp /build/target/release/rustnet /dist/
|
|
#
|
|
# Usage (without eBPF - smaller binary, ~5.2MB vs ~6.5MB):
|
|
# docker build -f Dockerfile.static --build-arg FEATURES="--no-default-features" -t rustnet-static .

# Install build dependencies
|
|
# - musl-dev: musl C library headers
|
|
# - libpcap-dev: libpcap headers and static library (/usr/lib/libpcap.a)
|
|
# - pkgconfig: for finding library paths
|
|
# - build-base: basic build tools (make, gcc, etc.)
|
|
# - perl: required by some build scripts (ring crate)
|
|
# - elfutils-dev: libelf for eBPF (includes static library)
|
|
# - zlib-dev/zlib-static: compression library
|
|
# - zstd-dev/zstd-static: Zstandard compression (required by elfutils 0.189+)
|
|
# - clang/llvm: for eBPF compilation
|
|
# - linux-headers: kernel headers for eBPF
