# How to secure access to MinIO on Kubernetes with TLS [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

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.

        // In this test, we expect IOException when project ID is blank
        try {
            conn.connect();
            fail("Should throw IOException when project ID is not set");
        } catch (IOException e) {
            assertTrue(e.getMessage().contains("GCS_PROJECT_ID is blank"));
        }

## Introduction

first connect fails. This is necessary for IPv4+IPv6 and services hosted in redundant data
centers. OkHttp supports modern TLS features (TLS 1.3, ALPN, certificate pinning). It can be
configured to fall back for broad connectivity.

Using OkHttp is easy. Its request/response API is designed with fluent builders and immutability. It
supports both synchronous blocking calls and async calls with callbacks.

A well behaved user agent
