### Configure TLS

To enable TLS for MinIO containers, acquire TLS certificates from a CA or create self-signed certificates. While creating / acquiring certificates ensure the corresponding domain names are set as per the standard [DNS naming conventions](https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/#pod-identity) in a Kubernetes StatefulSet (for a distributed MinIO setup). Then create a secret using

* Make CoreDNS be the default DNS server in kube-up (instead of kube-dns formerly).  ([#67569](https://github.com/kubernetes/kubernetes/pull/67569), [@fturib](https://github.com/fturib))
    * It is still possible to deploy kube-dns by setting CLUSTER_DNS_CORE_DNS=false.

### SIG Network

For 1.13, the areas of focus were in IPv6, DNS improvements and some smaller items:
CoreDNS is now the default cluster DNS passing all of the scale/resource usage tests
Node-local DNS cache feature is available in Alpha. This feature deploys a lightweight DNS caching Daemonset that avoids the conntrack and converts queries from UDP to more reliable TCP.

### Other notable changes

* Update kube-dns to Version 1.14.10. Major changes: ([#62676](https://github.com/kubernetes/kubernetes/pull/62676), [@MrHohn](https://github.com/MrHohn))
    * - Fix a bug in DNS resolution for externalName services
    * and PTR records that need to query from upstream nameserver.
