* Default values differ between the Kubelet's componentconfig (config file) API and the Kubelet's command line. Be sure to review the default values when migrating to using a config file. For example, the authz mode is set to "AlwaysAllow" if you rely on the command line, but defaults to the more secure "Webhook" mode if you load config from a file.

for the kubelet in the dropin, a structured configuration file for the kubelet is used, and is expected to be present in `/var/lib/kubelet/config.yaml`. For runtime-detected, instance-specific configuration values, a environment file with dynamically-generated flags at `kubeadm init` or `kubeadm join` run time is used. Finally, if you want to override something specific for the kubelet that can't be done via the kubeadm Configuration file (which is preferred), you might add flags to the `KUBELET_EXTRA_ARGS`...

#### Configuration file changes:

#### kube-apiserver:

  * The `--audit-policy-file` option is required if the `AdvancedAuditing` feature is not explicitly turned off (`--feature-gates=AdvancedAuditing=false`) on the API server.
  * The audit log file defaults to JSON encoding when using the advanced auditing feature gate.
  * An audit policy file without either an `apiVersion` or a `kind` field may be treated as invalid.
  * The webhook and log file now output the `v1beta1` event format.

- kube-apiserver: The `ResourceQuota` admission plugin configuration referenced from `--admission-control-config-file` admission config has been promoted to `apiVersion: apiserver.config.k8s.io/v1`,...

    - the secret is a serialized version of `azure.json` file with key cloud-config. And the secret name is azure-cloud-provider.
    - A new option cloudConfigType has been added to the cloud-config file. Supported values are: `file`, `secret` and `merge` (`merge` is the default value).
