For a [distributed MinIO setup](https://min.io/docs/minio/kubernetes/upstream/operations/installation.html#procedure), where there are multiple pods with different domain names expected to run, you will either need wildcard certificates valid for all the domains or have specific certificates for each domain. If you are going to use specific certificates, make sure to create Kubernetes secrets accordingly.
