Add 'silo healthcheck [live|ready|cluster|cluster-read]', a thin
anonymous HTTP client for the server's own /minio/health/* endpoints,
so containers without a shell, curl, or mc can still run health
checks. Design: silo.pgsty.com/compatibility/feature/healthcheck/
The check vocabulary maps 1:1 onto the health API paths; the probe
target is derived from the server's own --address/MINIO_ADDRESS
contract with HTTPS auto-detected from the certs directory, and can
be overridden with --url. Exit codes are 0/1 only (Docker reserves 2);
diagnostics (x-minio-server-status, quorum headers) go into a single
output line for docker inspect. The request is strictly anonymous (a
credentialed request would be rejected by the reserved-path guard),
the transport bypasses HTTP_PROXY, and certificate verification is
skipped to match kubelet HTTPS probe behavior. Cluster checks default
to a 15s deadline so the server's 10s cluster_deadline can elapse.
Compatibility notes: the preserved /minio/health/* path literals and
the MINIO_ADDRESS env var are upstream wire/config surface, reused on
purpose; the rebrand-guard baseline is regenerated for the new route
literals (tests included) with zero new exported symbols. The docker
entrypoint argv translation learns the new command name.
Verified: unit tests, entrypoint tests, go vet, plus an end-to-end
run against a live server covering all four checks, --maintenance
(412), --json, usage errors, unreachable and timeout paths.

README, README_ZH, SECURITY, COMPLIANCE, CONTRIBUTING, NOTICE,
code_of_conduct, the vulnerability and PR-etiquette documents, the GitHub issue
and pull request templates, and the docs/ tree all present Silo as the product.
The Grafana dashboards under docs/metrics/prometheus/grafana/ have their panel
titles and descriptions rebranded while every minio_* query, label and
expression is left alone, so existing alerts and recording rules keep matching.
The distinction the review demanded is applied per hit rather than by
search-and-replace:
- Product and command text becomes Silo and silo: install and run instructions,
systemd examples, compose services, download links, badges.
- Protocol and interface text keeps MinIO: MINIO_* variables, minio_* metrics,
x-minio-* headers, /minio/* routes, .minio.sys, arn:minio, and API field and
error names.
- Attribution keeps MinIO and gains the fork's own: the AGPL obligations,
original copyright, CREDITS and NOTICE stay, with the modification notice
added alongside rather than replacing them.
- Historical and third-party references are left as facts, not rewritten for
brand tidiness.
README and README_ZH each carry an explicit non-affiliation notice, document
the side-by-side package migration including the
/etc/systemd/system/silo.service.d/10-legacy-user.conf drop-in for keeping a
legacy UID/GID, and state that recursive chown is never performed. The trademark
attribution uses the policy's approved "based on MinIO technology" wording, not
the shortened form the policy rejects.
github.com/pgsty/minio links are left in place and labelled transitional. The
repository has not been renamed, and rewriting them now would produce documented
URLs that 404 until the cutover; they change in the cutover commit together with
the goreleaser release target, the OCI source label and the raw-content branch.

Readiness as no reasoning to be cluster scope
because that is not how the k8s networking works
for pods, all the pods to a deployment are not
sharing the network in a singleton. Instead they
are run as local scopes to themselves, with
readiness failures the pod is potentially taken
out of the network to be resolvable - this
affects the distributed setup in myriad of
different ways.
Instead readiness should behave like liveness
with local scope alone, and should be a dummy
implementation.
This PR all the startup times and overal k8s
startup time dramatically improves.
Added another handler called as `/minio/health/cluster`
to understand the cluster scope health.
Minio server supports healthcheck and prometheus related
unauthenticated endpoints. This document summarizes this
information in a single place and add links for more detailed
documentation if needed.
