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

- Kubernetes cluster with `kubectl` configured.

- Acquire TLS certificates, either from a CA or [create self-signed certificates](https://docs.min.io/community/minio-object-store/operations/network-encryption.html).

## Let's Encrypt { #lets-encrypt }

Before Let's Encrypt, these **HTTPS certificates** were sold by trusted third parties.

The process to acquire one of these certificates used to be cumbersome, require quite some paperwork and the certificates were quite expensive.

But then **<a href="https://letsencrypt.org/" class="external-link" target="_blank">Let's Encrypt</a>** was created.
