### SIG AWS

In v1.13 we worked on tighter integrations of Kubernetes API objects with AWS services. These include three out-of-tree alpha feature releases:

1) Alpha for AWS ALB (Application Load Balancer) integration to Kubernetes Ingress resources.

* Allow kube- and cloud-controller-manager to listen on ports up to 65535. ([#65860](https://github.com/kubernetes/kubernetes/pull/65860), [@sttts](https://github.com/sttts))
* Allow kube-scheduler to listen on ports up to 65535. ([#65833](https://github.com/kubernetes/kubernetes/pull/65833), [@sttts](https://github.com/sttts))

  // volumeNamespace specifies the scope of the volume within StorageOS.  If no
  // namespace is specified then the Pod's namespace will be used.  This allows the
  // Kubernetes name scoping to be mirrored within StorageOS for tighter integration.
  // Set VolumeName to any name to override the default behaviour.
  // Set to "default" if you are not using namespaces within StorageOS.
  // Namespaces that do not pre-exist within StorageOS will be created.

- Add --permit-address-sharing flag to `kube-apiserver` to listen with `SO_REUSEADDR`. While allowing to listen on wildcard IPs like 0.0.0.0 and specific IPs in parallel, it avoids waiting for the kernel to release socket in `TIME_WAIT` state, and hence, considerably reducing `kube-apiserver` restart times under certain conditions.

* Performance test framework and basic tests for the IPAM controller, to simulate behavior of the four supported modes under lightly loaded and loaded conditions, where load is defined as the number of operations to perform as against the configured kubernetes.

- 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:

cluster-internal resources installed by kubeadm will be overwritten when upgrading from v1.6 to v1.7. ([#47081](https://github.com/kubernetes/kubernetes/pull/47081), [@luxas](https://github.com/luxas))

* kubeadm deb/rpm packages: cAdvisor doesn't listen on `0.0.0.0:4194` without authentication/authorization because of the possible information leakage. The cAdvisor API can still be accessed via `https://{node-ip}:10250/stats/`, though. ([kubernetes/release#356](https://github.com/kubernetes/release/pull/356),...
