kubeadm: Promoted the feature gate `ControlPlaneKubeletLocalMode` to Beta. By default, kubeadm will use the local kube-apiserver endpoint for the kubelet when creating a cluster with `kubeadm init` or when joining control plane nodes with `kubeadm join`. Enabling the feature gate also affects the `kubeadm init phase kubeconfig kubelet` phase, where the flag `--control-plane-endpoint` no longer affects the generated kubeconfig `Server` field, but the flag `--apiserver-advertise-address` can now be used...

Es hängt **stark** davon ab, wie Sie **Ihr System deployen**, und hängt wahrscheinlich mit der Art und Weise zusammen, wie Sie Programme starten, Neustarts durchführen, usw.

Hier sind einige mögliche Ideen:

* Ein „Init-Container“ in Kubernetes, der vor Ihrem Anwendungs-Container ausgeführt wird
* Ein Bash-Skript, das die Vorab-Schritte ausführt und dann Ihre Anwendung startet

This will **depend heavily** on the way you **deploy your system**, and it would probably be connected to the way you start programs, handling restarts, etc.

Here are some possible ideas:

* An "Init Container" in Kubernetes that runs before your app container
* A bash script that runs the previous steps and then starts your application
    * You would still need a way to start/restart *that* bash script, detect errors, etc.

Variables may also be initialized using functions named <code>init</code>
declared in the package block, with no arguments and no result parameters.
</p>

<pre>
func init() { … }
</pre>

<p>
Multiple such functions may be defined per package, even within a single
source file. In the package block, the <code>init</code> identifier can
be used only to declare <code>init</code> functions, yet the identifier

/// info

如果你使用 Kubernetes，这可能是 <a href="https://kubernetes.io/docs/concepts/workloads/pods/init-containers/" class="external-link" target="_blank">Init Container</a>。

如果在你的用例中，运行前面的步骤**并行多次**没有问题（例如，如果你没有运行数据库迁移，而只是检查数据库是否已准备好），那么你也可以将它们放在开始主进程之前在每个容器中。

- The flag `--experimental-patches` is now deprecated and will be removed in a future release. You can migrate to using the new flag `--patches`. Add a new field `{Init|Join}Configuration.patches.directory` that can be used for the same purpose. For `init` and `join` it is now recommended that you migrate to configure patches via `{Init|Join}Configuration.patches.directory`. For the time being, these flags can be mixed with `--config`, but that might change in the future. On a command line, the last...
