# Temporary helper: build freepeak/leankg:embeddings with the embeddings feature ON.
# Use: `docker build -f Dockerfile.embed -t freepeak/leankg:embeddings .`
# This is a build-only artifact; not part of the prod image.
#
# Why a separate file: the published Hub image is built without embeddings
# to stay slim. We need --features=embeddings for cold embed on be.
