# FalkorDB graph module compiled from source, served by Valkey 9 (newest).
#
# The upstream falkordb/falkordb image still ships its own Redis-lineage
# server; we want the module on Valkey 9.x, so we compile it in-container
# (multi-stage: heavy toolchain never reaches the runtime image).
#
# Build (slow the first time — GraphBLAS is a big compile):
#   podman build -t knut-falkordb-valkey9 -f containers/falkordb-valkey9/Containerfile .
#
# Run:
#   podman run -p 6379:6379 knut-falkordb-valkey9
