<h3 id="Bootstrapping">Bootstrapping</h3>

<p>
Current implementations provide several built-in functions useful during
bootstrapping. These functions are documented for completeness but are not
guaranteed to stay in the language. They do not return a result.

- Kubectl create job command has been added. ([#60316](https://github.com/kubernetes/kubernetes/pull/60316), [@soltysh](https://github.com/soltysh)) Courtesy of SIG CLI
- Kubelet serving certificate bootstrapping and rotation has been promoted to beta status. ([#66726](https://github.com/kubernetes/kubernetes/pull/66726), [@liggitt](https://github.com/liggitt)) Courtesy of SIG Auth, and SIG Node

- Add the following metrics:
  - network_plugin_operations_total
  - network_plugin_operations_errors_total ([#93066](https://github.com/kubernetes/kubernetes/pull/93066), [@AnishShah](https://github.com/AnishShah))

* kubelet: fix fail to close kubelet->API connections on heartbeat failure when bootstrapping or client certificate rotation is disabled ([#78016](https://github.com/kubernetes/kubernetes/pull/78016), [@gaorong](https://github.com/gaorong))

- Kubeadm increased to 5 minutes its timeout for the TLS bootstrapping process to complete upon join ([#89735](https://github.com/kubernetes/kubernetes/pull/89735), [@rosti](https://github.com/rosti)) [SIG Cluster Lifecycle]

* corrects a race condition in bootstrapping aggregated cluster roles in new HA clusters ([#63761](https://github.com/kubernetes/kubernetes/pull/63761), [@liggitt](https://github.com/liggitt))
