The dependency injection system requires pre-registration of the dependencies and the dependencies are solved based on the declared types. So, it's not possible to declare more than one "component" that provides a certain type.

## Known Issues

	// Use bitwise-AND and check if the result is non-zero.
	return h&flag != 0

// s3APIMiddleware - performs some common handler functionality for S3 API
// handlers.

// It is set per-"handler function registration" in the router to allow for
// behavior modification via flags.

// This middleware always calls `collectAPIStats` to collect API stats.

// - sets up call to send AuditLog
//
// While this is a middleware function (i.e. it takes a handler function and
// returns one), due to flags being passed based on required conditions, it is
// done per-"handler function registration" in the router.
//
// The passed in handler function must be a method of `adminAPIHandlers` for the
// name displayed in logs and trace to be accurate. The name is extracted via
// reflection.

- Added a health check for the device plugin gRPC registration server. When the registration server is down, kubelet is marked as unhealthy. If systemd watchdog is configured, this will result in a kubelet restart. ([#128432](https://github.com/kubernetes/kubernetes/pull/128432), [@zhifei92](https://github.com/zhifei92))...

* Kubernetes 1.12 also enables [Kubelet device plugin registration](https://github.com/kubernetes/enhancements/issues/595) feature by default. Before upgrading to 1.12, ensure the `driver-registrar` CSI sidecar container for your CSI driver is configured to handle plugin registration (set the `--kubelet-registration-path` parameter on `driver-registrar` to expose a new unix domain socket to handle Kubelet Plugin Registration).

### Other notable changes

* Make logdump support kubemark and support gke with 'use_custom_instance_list' ([#51834](https://github.com/kubernetes/kubernetes/pull/51834), [@shyamjvs](https://github.com/shyamjvs))
* Fixes an issue with APIService auto-registration affecting rolling HA apiserver restarts that add or remove API groups being served. ([#51921](https://github.com/kubernetes/kubernetes/pull/51921), [@liggitt](https://github.com/liggitt))
