Using PodSecurityPolicy for MinIO Pods 
This document explains how to apply PodSecurityPolicy to MinIO Pods created by the MinIO Operator. A Pod Security Policy is a cluster-level resource that controls security sensitive aspects of the pod specification. Read more in Kubernetes PodSecurityPolicy Documentation.
Getting Started
Use the example to apply a custom PodSecurityPolicy to all the MinIO Pods created by the Operator.
kubectl create -f https://github.com/minio/operator/tree/master/examples/tenant-pod-security-policy.yaml
This file creates a custom PodSecurityPolicy. Then it creates a ClusterRole attached to the PodSecurityPolicy. Finally a ClusterRoleBinding bounds the ClusterRole to a ServiceAccount which is added to all the MinIO Pods created by the MinIO Operator.
