# Minimal compose for the TCP proxy with optional BPF sockmap zero-copy
# relay. Uses host networking so sockmap can attach to real kernel
# sockets and SO_REUSEPORT shards across workers on the host's real
# NIC / loopback stack.
#
# Usage:
#
#   # Fixed backend, userspace relay:
#   TCP_BACKEND_ENDPOINT=10.0.0.2:5432 \
#     docker compose -f docker-compose.tcp.yml up --build
#
#   # With sockmap zero-copy:
#   TCP_SOCKMAP_ENABLED=1 \
#   TCP_BACKEND_ENDPOINT=10.0.0.2:5432 \
#     docker compose -f docker-compose.tcp.yml up --build
#
#   # Custom resolver:
#   docker compose -f docker-compose.tcp.yml \
#     run -v ./resolver.php:/etc/utopia-proxy/resolver.php:ro tcp-proxy
