SeaweedFS

SeaweedFS exposes an S3 endpoint via its s3 server.

#YAML

backends:
  - id: seaweedfs
    name: "SeaweedFS"
    type: s3v4
    endpoint: http://seaweedfs:8333
    region: us-east-1
    access_key_env: SEAWEED_ACCESS_KEY
    secret_key_env: SEAWEED_SECRET_KEY
    path_style: true

#What works

• Bucket and object CRUD.
• Multipart uploads.
• The embedded SigV4 proxy.

#Notes

• Path-style only.
• SeaweedFS supports a subset of S3 features. Versioning, lifecycle, and bucket policy support depends on the SeaweedFS release — Stowage surfaces upstream errors directly rather than pre-flighting.
• The native admin API for SeaweedFS is not yet implemented (Capabilities.AdminAPI="").
