Choose an Object Storage Provider

Panoramica​

Ilum runs entirely on S3-compatible object storage. The bundled helm_aio chart supports two providers natively (RustFS e MinIO) and integrates with any external S3 service that the cluster can reach. Two further providers (Garage e AlgaFS) are on the roadmap and already accommodated by the provider registry. This page documents the trade-offs and helps an operator decide which path to take.

Decision tree​

Three short branches cover the common deployment shapes.

"I want zero-ops bundled storage"​

Use the default. MinIO is enabled out of the box in the 6.7.x line.

helm install ilum ilum/helm_aio

To opt into RustFS (the planned default from 6.8.0) instead, enable it and disable MinIO:

helm install ilum ilum/helm_aio \
  --mettere rustfs.enabled=vero \
  --mettere minio.enabled=falso

Either choice creates the ilum-objectstorage Service alias and wires every bundled consumer through it.

"I already operate an S3-compatible backend"​

Disable both bundled providers and point Ilum at the existing service.

helm install ilum ilum/helm_aio \
  --mettere rustfs.enabled=falso \
  --mettere minio.enabled=falso \
  --mettere objectStorage.endpoint=https://s3.us-east-1.amazonaws.com

For provider-specific configuration recipes, refer to Provider Reference: External S3.

"I want to benchmark providers side by side"​

Run two providers concurrently and route user traffic through the alias. Set objectStorage.activeProvider explicitly when more than one provider is enabled. The alias selector flips on a single helm upgrade --set.

helm install ilum ilum/helm_aio \
  --mettere minio.enabled=vero \
  --mettere rustfs.enabled=vero \
  --mettere objectStorage.activeProvider=rustfs

Reversibility​

Switching providers is a single helm upgrade --set away. The ilum-objectstorage Service alias selector flips atomically; every bundled consumer picks up the new endpoint on its next connection.

The data side is not reversible without a migration. Refer to Migrate Between Providers for the mirror procedure that runs before the alias flip.

Constraints to be aware of​

  • RustFS alpha distributed mode. The bundled chart configures standalone mode. Erasure coding and multi-replica distribution are available upstream but marked "under testing".
  • MinIO console pin. Le MinIO console binds itself to the absolute URL configured by MINIO_BROWSER_REDIRECT_URL. The bundled default pins it to /esterno/minio/. The Ilum UI's /external/object-storage/ alias path redirects to that absolute URL when MinIO is the active provider.
  • No simultaneous writes across providers. The cutover model assumes a single active provider at any given time. Operators that want multi-region replication should configure it at the provider layer, not by enabling two Ilum providers concurrently.
