Bucket Storage Links (*-bucket)

Links to MinIO bucket sub-components provide S3-compatible object storage access

🪣 What These Links Do

Inject S3 endpoint URL into environment variables

Provide bucket-specific access credentials

Configure bucket name for the application

Set region (minio) for S3 compatibility

🔗 Supported Link Types

⚙️ Generated Environment Variables

# Automatically configured when you create a bucket link
S3_ENDPOINT=auto-configured
S3_BUCKET={bucket_name}
S3_ACCESS_KEY={bucket_access_key}
S3_SECRET_KEY={bucket_secret_key}
S3_REGION=minio
S3_USE_PATH_STYLE=true

💡 Key Points

Multiple buckets: You can link to multiple bucket sub-components

Separate credentials: Each bucket uses its own access credentials, not MinIO root credentials

Auto-configuration: All connection details are automatically configured
