use the --node-ip flag with one of the unspecified addresses 0.0.0.0 or ::, to create the Node with the IP of the default gateway of the corresponding IP family and then delegating the responsibility to the external cloud provider. This solve the bootstrap problems of out of tree cloud providers that are deployed as Pods within the cluster.

- kubeadm now deletes the bootstrap-kubelet.conf file after TLS bootstrap
  User relying on bootstrap-kubelet.conf should switch to kubelet.conf that contains node credentials ([#80676](https://github.com/kubernetes/kubernetes/pull/80676), [@fabriziopandini](https://github.com/fabriziopandini))

  * Automatically install updates on boot & reboot
  * Use optimized image based on Jessie by default
  * Add support for Ubuntu Wily
  * Master is configured with automatic restart-on-failure, via CloudWatch
  * Bootstrap reworked to be more similar to GCE; better supports reboots/restarts
  * Use an elastic IP for the master by default
  * Experimental support for node spot instances (set NODE\_SPOT\_PRICE=0.05)

#### GCE

* Fix a typo in prometheus-to-sd configuration, that drops some stackdriver metrics. ([#56473](https://github.com/kubernetes/kubernetes/pull/56473), [@loburm](https://github.com/loburm))
* Update jquery and bootstrap dependencies ([#56447](https://github.com/kubernetes/kubernetes/pull/56447), [@dashpole](https://github.com/dashpole))
