- Fix an error when using external etcd but storing etcd certificates in the same folder with the same name used by kubeadm for local etcd certificates; for an older version of kubeadm, the workaround is to avoid file name used by kubeadm for local etcd. ([#80867](https://github.com/kubernetes/kubernetes/pull/80867), [@fabriziopandini](ht...

### Failing Test

- Kubelet: the HostPort implementation in dockershim was not taking into consideration the HostIP field, causing that the same HostPort can not be used with different IP addresses.

				epstest.MakeEndpointAddress("1.2.3.5", "unnamed"),
			},
			[]api.EndpointPort{
				epstest.MakeEndpointPort("", 80),
			}),
		epstest.MakeEndpoints("named",
			[]api.EndpointAddress{
				epstest.MakeEndpointAddress("1.2.3.6", "named"),
			},
			[]api.EndpointPort{
				epstest.MakeEndpointPort("p", 80),
				epstest.MakeEndpointPort("q", 81),
			}),

- Multiple Kubernetes clusters can now share the same resource group
    - When upgrading from previous releases, issues will arise with public IPs if multiple clusters share the same resource group. To solve these problems, make the following changes to the cluster:

* fix vmss dirty cache issue in disk attach/detach on vmss node ([#85158](https://github.com/kubernetes/kubernetes/pull/85158), [@andyzhangx](https://github.com/andyzhangx))
* fix race condition when attach/delete azure disk in same time ([#84917](https://github.com/kubernetes/kubernetes/pull/84917), [@andyzhangx](https://github.com/andyzhangx))

* Add note to docs: [Include the same router multiple times with different `prefix`](https://fastapi.tiangolo.com/tutorial/bigger-applications/#include-the-same-router-multiple-times-with-different-prefix). PR [#348](https://github.com/tiangolo/fastapi/pull/348).

* Fix OpenAPI/JSON Schema generation for two functions with the same name (in different modules) with the same composite bodies.

- `oc describe quota` used has the same unit format as hard ([#102177](https://github.com/kubernetes/kubernetes/pull/102177),...

	// if both fields are non-empty, they must have the same value. For backwards
	// compatibility, when namespace isn't specified in dataSourceRef,
	// both fields (dataSource and dataSourceRef) will be set to the same
	// value automatically if one of them is empty and the other is non-empty.
	// When namespace is specified in dataSourceRef,
	// dataSource isn't set to the same value and must be empty.

- Fix a bug in port-forward: named port not working with service ([#85511](https://github.com/kubernetes/kubernetes/pull/85511), [@oke-py](https://github.com/oke-py)) [SIG CLI]

* The validated docker versions are the same as for v1.9: 1.11.2 to 1.13.1 and 17.03.x ([ref](https://github.com/kubernetes/kubernetes/blob/release-1.10/test/e2e_node/system/docker_validator_test.go))
* The Go version is go1.9.3, as compared to go1.9.2 in v1.9. ([#59012](https://github.com/kubernetes/kubernetes/pull/59012))
