Local S3 Storage Without MinIO: SeaweedFS and Garage in Docker Compose

Read on sitepoint.com

Summary

The article shows how to run SeaweedFS and Garage together in a single Docker‑Compose file to provide low‑memory, S3‑compatible local storage, avoiding MinIO’s larger footprint and licensing concerns. It includes bucket‑seeding scripts and a Node.js test suite using AWS SDK v3.

  • Docker‑Compose defines SeaweedFS (single‑process server) with an init sidecar that creates a test bucket via `weed shell`.
  • Garage is configured via `garage.toml` (SQLite metadata, replication_factor=1) and an init script that assigns a layout, creates an API key, and provisions a bucket.
  • Both services expose S3 endpoints (SeaweedFS on 8333, Garage on 3900) that the shared Node.js test script validates for PutObject, GetObject, multipart upload, and pre‑signed URLs.
  • SeaweedFS uses ~60‑100 MiB idle RAM, Garage ~30‑60 MiB, compared to MinIO’s ~300‑400 MiB, making them suitable for CI runners and laptops.

Engineers building CI pipelines or developing locally who need S3‑compatible storage without MinIO’s resource or licensing overhead should consider this SeaweedFS‑and‑Garage combo.

  4. Accelerating the borderless Lakehouse: Announcing preview of cross-cloud caching

    Google Cloud previewed cross‑cloud caching for its Borderless Lakehouse. The feature caches sub‑file Parquet blocks in Google Cloud, encrypts them with GMEK, isolates cache per tenant/region, and validates freshness via metadata checks. In tests it can reduce cross‑cloud data transfer to <5% of the original size, lowering query latency and cost for Iceberg tables stored in other clouds. BigQuery…
