Lake Release Note 2026-08-22

2026-08-22

Every port the stack binds became configurable, and nothing in the repository writes one down twice.

• Ports live in .env. MINIO_API_PORT, MINIO_CONSOLE_PORT, LAKEKEEPER_PORT, POSTGRES_PORT, and CONSOLE_PORT are read by compose.yaml, the init scripts, the Makefile, and the CLI alike, and one number serves both what a service listens on and what it publishes. A port literal anywhere else is now a bug.
• ports, on both front ends. make ports and the console's new Ports page show the configured value, what the running stack publishes, and where the two have drifted; --set KEY=PORT writes a new value after checking it is in range, unclaimed by another component, and free on the host.
• The catalog follows MinIO. MinIO's address is stored in the warehouse's storage profile, so lakekeeper-init now compares the two and repoints an existing warehouse instead of leaving it vending credentials for a dead address.
• The attach SQL is a template. scripts/duckdb-entrypoint.sh renders sql/attach.sql.template into /tmp/attach.sql at container start, filling in the warehouse name and catalog endpoint from the environment, so no DuckDB client carries either.
