With Kubernetes 1.24, the [gRPC probes functionality](https://github.com/kubernetes/enhancements/issues/2727)
has entered beta and is available by default. You can now [configure startup, liveness, and readiness probes](https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/#configure-probes) for your gRPC app
natively within Kubernetes, without exposing an HTTP endpoint or
using an extra executable.

* **[alpha]** New Bootstrap Token authentication and management method. Works well with kubeadm. kubeadm now supports managing tokens, including time based expiration, after...

* allow authentication through a front-proxy ([#35452](https://github.com/kubernetes/kubernetes/pull/35452), [@deads2k](https://github.com/deads2k))
* On GCI, cleanup kubelet startup ([#35319](https://github.com/kubernetes/kubernetes/pull/35319), [@vishh](https://github.com/vishh))

- Fix image pulling failure when IMDS is unavailable in kubelet startup ([#110523](https://github.com/kubernetes/kubernetes/pull/110523), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider]

			s.end -= s.start
			s.start = 0
		}
		// Is the buffer full? If so, resize.

* Ein Bash-Skript, das die Vorab-Schritte ausführt und dann Ihre Anwendung startet
    * Sie benötigen immer noch eine Möglichkeit, *dieses* Bash-Skript zu starten/neu zu starten, Fehler zu erkennen, usw.

Konkretere Beispiele hierfür mit Containern gebe ich Ihnen in einem späteren Kapitel: [FastAPI in Containern – Docker](docker.md){.internal-link target=_blank}.

- Fixed a bug where init containers may fail to start due to a temporary container runtime failure. ([#127213](https://github.com/kubernetes/kubernetes/pull/127213), [@SergeyKanzhelev](https://github.com/SergeyKanzhelev)) [SIG Node]

- Reduced GCE log rotation check from 1 hour to every 5 minutes.  Rotation policy is unchanged (new day starts, log file size > 100MB). ([#76352](https://github.com/kubernetes/kubernetes/pull/76352), [@jpbetz](https://github.com/jpbetz))
- GCE/Windows: disabled stackdriver logging agent to prevent node startup failures ([#76099](https://github.com/kubernetes/kubernetes/pull/76099), [@yujuhong](https://github.com/yujuhong))
