#### kube-dns
* Updates kube-dns to 1.14.2 ([#45684](https://github.com/kubernetes/kubernetes/pull/45684), [@bowei](https://github.com/bowei))

   * Support kube-master-url flag without kubeconfig

   * Fix concurrent R/Ws in dns.go

   * Fix confusing logging when initialize server

   * Fix printf in cmd/kube-dns/app/server.go

  // Set DNS policy for the pod.
  // Defaults to "ClusterFirst".
  // Valid values are 'ClusterFirstWithHostNet', 'ClusterFirst', 'Default' or 'None'.
  // DNS parameters given in DNSConfig will be merged with the policy selected with DNSPolicy.
  // To have DNS options set along with hostNetwork, you have to specify DNS policy
  // explicitly to 'ClusterFirstWithHostNet'.

* Revert [#63905](https://github.com/kubernetes/kubernetes/pull/63905): Setup dns servers and search domains for Windows Pods. DNS for Windows containers will be set by CNI plugins. ([#66587](https://github.com/kubernetes/kubernetes/pull/66587), [@feiskyer](https://github.com/feiskyer))

### 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.

* 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.

* 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.

- Bind dns-horizontal containers to linux nodes to avoid Windows scheduling on kubernetes cluster includes linux nodes and windows nodes ([#83364](https://github.com/kubernetes/kubernetes/pull/83364), [@wawa0210](https://github.com/wawa0210)) [SIG Cluster Lifecycle and Windows]

- This PR sets the --cluster-dns flag value to kube-dns service IP whether or not NodeLocal DNSCache is enabled. NodeLocal DNSCache will listen on both the link-local as well as the service IP. ([#84383](https://github.com/kubernetes/kubernetes/pull/84383), [@prameshj](https://github.com/prameshj))
- kube-dns add-on:
  - All containers are now being executed under more restrictive privileges.
