This recipe showed you how to provision a completely Amazon S3 API-compatible service using MinIO deployed on Kubernetes. This service will be used later for disaster recovery and backing up applications running on Kubernetes.

In the Creating a MinIO S3 service recipe, in Step 1, when we deploy MinIO, it creates a LoadBalancer service at port 9000. Since we set the number of nodes to 4, a StatefulSet will be created with four replicas. Each will use the information set under the volumeClaimTemplates section to create a PVC. If storageClassName is not defined specifically, then the default storage class will be used. As a result, you will see four instance of PersistentVolumesClaim (PVC) created on the cluster to provide a highly available MinIO service.
