Also, note that the certificate has to contain the `Extended Key Usage: TLS Web Client Authentication`. Otherwise, MinIO would not accept the certificate as client certificate.

Now, the STS certificate-based authentication happens in 4 steps:

- Client sends HTTP `POST` request over a TLS connection hitting the MinIO TLS STS API.
- MinIO verifies that the client certificate is valid.

### TLS with SNI Extension { #tls-with-sni-extension }

**Only one process** in the server can be listening on a specific **port** in a specific **IP address**. There could be other processes listening on other ports in the same IP address, but only one for each combination of IP address and port.

This document explains how to configure MinIO server with TLS certificates on Kubernetes.

## 1. Prerequisites

- Familiarity with [MinIO deployment process on Kubernetes](https://docs.min.io/community/minio-object-store/operations/deployments/kubernetes.html).

- Kubernetes cluster with `kubectl` configured.

mountPath: {{ $casPath }} {{- end }} {{- end -}} {{/* Formats volume for Minio tls keys and trusted certs */}} {{- define "minio.tlsKeysVolume" -}} {{- if .Values.tls.enabled }} - name: cert-secret-volume secret: secretName: {{ .Values.tls.certSecret }} items: - key: {{ .Values.tls.publicCrt }} path: public.crt - key: {{ .Values.tls.privateKey }} path: private.key {{- end }} {{- if or .Values.tls.enabled (ne .Values.trustedCertsSecret "") }} {{- $certSecret := eq .Values.trustedCertsSecret "" | ternary ...

    * 上で述べたように、特定のIPとポートでリッスンできるプロセスは1つだけです。
    * これは、同じTLS Termination Proxyが証明書の更新処理も行う場合に非常に便利な理由の1つです。
    * そうでなければ、TLS Termination Proxyを一時的に停止し、証明書を取得するために更新プログラムを起動し、TLS Termination Proxyで証明書を設定し、TLS Termination Proxyを再起動しなければならないかもしれません。TLS Termination Proxyが停止している間はアプリが利用できなくなるため、これは理想的ではありません。


アプリを提供しながらこのような更新処理を行うことは、アプリケーション・サーバー（Uvicornなど）でTLS証明書を直接使用するのではなく、TLS Termination Proxyを使用して**HTTPSを処理する別のシステム**を用意したくなる主な理由の1つです。
