Dockerfile.duckdb

# ==============================================================================
# Traceway DuckDB Docker Image
# Single binary serving API and Frontend with an embedded SQLite main DB and a
# DuckDB telemetry DB. No external databases required. Optional S3 for blobs.
#
# Unlike Dockerfile.sqlite (pure Go, Alpine, CGO_ENABLED=0), DuckDB requires
# CGO and links prebuilt glibc static libraries, so this image builds and runs
# on Debian (glibc), not Alpine (musl).
# ==============================================================================

# ==============================================================================
# Stage 1: Build Frontend

# ==============================================================================
# Stage 2: Build Backend with embedded frontend (telemetry_duckdb tag = DuckDB telemetry)
# Built natively (no cross-compile) because CGO cross-compilation against the
# prebuilt DuckDB libraries is impractical; the benchmark SUT builds on-host.
