Migrate MinIO to External S3 Bucket for Scalability and Storage Management

[rapidfix]

Problem Summary

MinIO storage has reached its capacity limit (100% usage), causing critical storage issues for Milvus operations. This is impacting job execution and system stability. The current MinIO setup is not scalable for long-term use.

Proposed Solution

1. Migrate to External S3

   • Create a Hetzner S3 bucket
   • Transfer all data from MinIO to the S3 bucket
   • Configure Milvus to use the external S3 bucket

2. Implementation Steps

   • Backup all MinIO data
   • Create S3 bucket on Hetzner
   • Transfer data using S3-compatible tools
   • Update Milvus configuration to use external S3
   • Validate data integrity and system functionality

3. Contingency Plan

   • If migration fails, re-deploy MinIO with S3 integration
   • Restore from backup if data loss occurs

4. Documentation

   • Update deployment guides for S3 configuration
   • Add monitoring for S3 storage metrics

Required Configuration Changes

# Example S3 configuration for Milvus
objectStorage:
  s3:
    endpoint: "https://your-hetzner-s3-bucket.example.com"
    accessKey: "YOUR_ACCESS_KEY"
    secretKey: "YOUR_SECRET_KEY"
    bucket: "tee-worker-storage"
    useSSL: true
