Condensing the READMEs dropped the systemd drop-in that keeps data ownership stable when silo.service takes over an existing minio.service, which the rebrand guard pins in both files precisely so it cannot vanish quietly. The path is back as a clause in the install note rather than a section, so the guard is satisfied and the migration-critical detail stays discoverable in the repository, not only on the portal.

S3-compatible object storage — a MinIO fork maintained by PGSTY

Important
PGSTY Silo (hereinafter “Silo”) is an independent, community-maintained fork of the open-source MinIO server, published by Pigsty from
pgsty/silo. It is not affiliated with, endorsed by, or sponsored by MinIO, Inc. “MinIO” is used only to identify the upstream project and compatibility lineage.
Note
Renamed from
pgsty/miniotopgsty/silo, default branchmaster→main, on 2026-08-06. Artifacts under the original MinIO identity stay published on the archivedminiobranch and in releases up toRELEASE.2026-08-04T00-00-00Z.
Overview
PGSTY SILO keeps one maintained release line of the open-source MinIO server alive after upstream ended community distribution: builds, packages, multi-arch images, security fixes, and the full web console. Pigsty runs it in production as its PostgreSQL backup repository.
It follows one rule — the product and its delivery surfaces are renamed; the protocol and your data are not. Everything else lives on silo.pgsty.com.

Quick Start
docker run -d --name silo -p 9000:9000 -p 9001:9001 \
-e MINIO_ROOT_USER=minioadmin \
-e MINIO_ROOT_PASSWORD=change-me-long-password \
-v "$PWD/data:/data" \
docker.io/pgsty/silo:latest server /data --console-address ":9001"
Console on http://localhost:9001, S3 API on http://localhost:9000. The image bundles the client as mcli:
docker exec silo mcli alias set local http://127.0.0.1:9000 minioadmin change-me-long-password
docker exec silo mcli mb local/demo && docker exec silo mcli ls local
Warning
For production, pin a release, use unique credentials and TLS, monitor the service, keep independent backups, and test recovery. Start from the documentation.
Install
| Method | Where |
|---|---|
| Container | pgsty/silo, multi-arch for linux/amd64 and linux/arm64 |
| Binaries | GitHub Releases — Linux, macOS, Windows on amd64 and arm64 |
| Packages | RPM, DEB, and APK, also via the Pigsty repository |
| Kubernetes | Helm chart, see Download & Install |
| Source | go build -o silo . && ./silo --version |
Every release ships checksums, SPDX SBOMs, Sigstore-signed manifests, and GitHub build attestations. Installation methods and verification commands are documented at Download & Install; migrating from upstream MinIO — taking over an existing minio.service and its /etc/default/minio, and keeping data ownership stable with a /etc/systemd/system/silo.service.d/10-legacy-user.conf drop-in — is covered by the migration guide and the binary & service notes.
Compatibility
The S3 API, MINIO_* variables, minio_* metrics, x-minio-* headers, /minio/* routes, the github.com/minio/* import paths, and the on-disk format (including .minio.sys) are preserved and held in place by a CI compatibility check. Only Silo-owned delivery surfaces change: the silo executable, package, service, Helm chart, and container image — no minio binary alias is installed.
Every divergence from upstream is listed in the code-verified compatibility audit. Treat each release as a downstream upgrade: pin versions, read the release notes, and keep a rollback path.
Security & Contributing
Report vulnerabilities privately as described in SECURITY.md; every fix ships with a public advisory. Contributions are accepted inbound=outbound under AGPL-3.0-or-later with no CLA — only DCO sign-off (git commit -s) is required; see CONTRIBUTING.md.

GitHub does not generate a contributor graph for forks, so CONTRIBUTORS.md — not the Insights page — is this project's attribution record. It names everyone alongside the change or report they contributed.
Background
Upstream wound down its community edition: the web console was cut back to a stub, prebuilt community binaries stopped, and the community repository was archived. Silo exists to keep those deployments running. The fork is a means, not an identity — if upstream restores its community edition, we will narrow our scope and offer the fixes back.
The Manifesto is the project's public commitment in eleven articles, under one discipline: every article is either something already done with public evidence, or something explicitly refused. In short:
- Compatibility contract — the protocol and your data do not change, and every release documents its tested rollback target and path.
- The license cannot change — AGPLv3, no CLA, no copyright aggregation; nobody here, ourselves included, holds enough copyright to relicense on everyone else's behalf.
- The never list, append-only — no paywalling existing features, no registration wall on downloads, no telemetry (upstream's phone-home paths are removed outright), no CLA, no license change, no trademark enforcement against normal use.
- Security and release discipline — a public advisory for every fix, and a release every one to two months, at most a quarter apart. Judge both against the public record.
