# Two-stage Containerfile for the DarkFi capacity benchmark.
#
# Build context must be the repo root (not this directory), because
# fee-model/Cargo.toml uses path = "../../../" for darkfi deps:
#
#   cd /path/to/darkfi
#   podman build -t darkfi-capacity \
#       -f script/research/fee-model/Containerfile.capacity .
#
# Run:
#   podman run --rm --cpuset-cpus=0-3 --memory=8g \
#       -v ./out:/out darkfi-capacity
#
# The image bundles the capacity binary and the money contract WASM.
# The benchmark writes results to /out/capacity.json.
