# Build context is this repository's root (the workspace Cargo.toml / Cargo.lock
# and every member manifest live there). Build from the repo root:
#
#     docker build -f docker/stress/Dockerfile -t tidaldb:stress .
#
# tidal-stress is a pure-Rust HTTP client (tokio + reqwest/rustls): it depends on
# NONE of the engine crates, so this build never compiles tidal/tidal-net/usearch
# and needs no protoc/g++. Pin the builder to bookworm so its glibc matches the
# runtime; trixie's vectorized-math libmvec is handled by the trixie runtime below.
