SILO gives existing MinIO deployments an open release and security-maintenance path while preserving the S3 API, configuration, and operational contracts that make migration practical. This site covers installation, migration, administration, development, releases, and compatibility boundaries.

## Quickstart {#quickstart}

**Docker**

The commands below pin the current SILO server release. Example credentials are suitable only for a local evaluation.

See the [container deployment guide](/operations/deployments/baremetal-deploy-minio-as-a-container/) for persistent host paths, service management, and production considerations.

**Linux packages**

Use [Download & Install](/download/#server) to select the RPM, DEB, APK, or standalone archive for your architecture. Published release assets include SHA-256 checksums and build-provenance attestations.

Native packages install the server as `/usr/bin/silo`; the service keeps the established `MINIO_*` environment-variable contract. Review the [binary and package compatibility notes](/compatibility/binary/) before replacing an existing `minio` package.

**Existing MinIO**

Read the [migration guide](/compatibility/migration/) before changing images or binaries. Preserve the data volumes and configuration, stop every node running the old binary, and then start every node on the same pinned SILO release. Do not perform a mixed-binary rolling migration, and never use `docker compose down -v` on data you intend to keep.

**Kubernetes**

The archived MinIO Operator `v7.1.1` can run a SILO Tenant when its image is overridden to `pgsty/silo` with a tested tag or digest. Follow the [Tenant Helm guide](/operations/deployments/k8s-deploy-minio-tenant-helm-on-kubernetes/) and treat that Operator version as a frozen compatibility baseline, not an actively maintained dependency.
