# Multi-region tidalDB cluster image.

# Runs a simulated 3-region cluster (us-east, eu-west, ap-south) behind a
# single HTTP surface on port 9500. See docs/runbooks/cluster.md for the
# operational API.
# Pin the builder to bookworm so its glibc matches the bookworm-slim runtime;
# the default tag tracks trixie, whose `libmvec.so.1` is absent on bookworm.
