Back-Off-Neustart fehlgeschlagener Container - Fehler beim Synchronisieren des Pods in Minikube

Beim Versuch, Pods zu erstellen, tritt dieser Fehler auf. Es kommt sogar bei sehr verbreiteten Bildern wie Ubuntu, Alpine vor. Ich bin ziemlich neu in Kubernetes und benutze einen Minikube-Knoten (Version v0.24.1).

Befehl:

kubectl run ubuntu --image==ubuntu

Fehler :

Back-off restarting failed container - Error syncing pod

Seltsamerweise funktioniert es für das Nginx-Image.

Gemäß der Describe PodBefehlsliste wurde Ihr Container im Pod bereits fertiggestellt exit code 0, was über einen erfolgreichen Abschluss ohne Fehler / Probleme aussagt, aber der Lebenszyklus für den Podwar sehr kurz. Damit Pod kontinuierlich ausgeführt wird, müssen Sie eine Aufgabe angeben, die niemals abgeschlossen wird.
