## Running on Startup { #running-on-startup }

In most cases, when you create a web API, you want it to be **always running**, uninterrupted, so that your clients can always access it. This is of course, unless you have a specific reason why you want it to run only in certain situations, but most of the time you want it constantly running and **available**.

### In a Remote Server { #in-a-remote-server }

    *   Pod Security Policy can now manage access to specific FlexVolume drivers.([#53179](https://github.com/kubernetes/kubernetes/pull/53179),[ @wanghaoran1988](https://github.com/wanghaoran1988))
    *   To prevent unauthorized access to CHAP Secrets, you can now set the secretNamespace storage class parameters for the following volume types:

* The kubelet API is now secured, only cluster admins are allowed to access it.
* Insecure access to the API Server over `localhost:8080` is now disabled.
* The control plane components now talk securely to each other. The API Server talks securely to the kubelets in the cluster.
