Hanzo AI
409a4c8390
Replaces all ghcr.io/hanzoai/<svc>:latest pins with the latest published semver tag for each service. Per CLAUDE.md auto-bump policy: mutable branch tags (:latest, :main, :dev) are deprecated for cluster pins — only immutable semver permitted. Bulk update across services with published v* tags. Services without a published semver remain on :latest until their release pipeline cuts a v* tag.

Verify Connectivity
Use any S3-compatible client. With the Hanzo S3 CLI (s3):
s3 alias set hanzo http://localhost:9000 admin changeme123
s3 admin info hanzo
s3 mb hanzo/my-bucket
s3 cp ~/data/model.safetensors hanzo/my-bucket/
s3 ls hanzo/my-bucket/
SDKs
Hanzo S3 is fully S3-compatible. Use any S3 SDK:
| Language | Package |
|---|---|
| Go | @hanzo/s3-go |
| JavaScript / TypeScript | @hanzo/s3 |
| Python | hanzo-s3 |
Standard AWS SDKs (aws-sdk-go, boto3, @aws-sdk/client-s3) also work without modification.
