Recuo ao reiniciar o contêiner com falha - Erro ao sincronizar o pod no Minikube

Estou enfrentando esse erro ao tentar criar pods. Está ocorrendo com imagens muito comuns, como o Ubuntu, o Alpine também. Sou bastante novo no Kubernetes e estou usando um Minikube Node (versão v0.24.1)

Comando:

kubectl run ubuntu --image==ubuntu

Erro :

Back-off restarting failed container - Error syncing pod

Descrever o comando Pod:

Curiosamente, ele funciona para a imagem nginx.

De acordo com a Describe Podlista de comandos, seu contêiner dentro do Pod já foi concluído exit code 0, o que indica a conclusão bem-sucedida sem erros / problemas, mas o ciclo de vida do mesmo Podfoi muito curto. Para manter o Pod funcionando continuamente, você deve especificar uma tarefa que nunca será concluída.

apiVersion: v1
kind: Pod
metadata:
  name: ubuntu
spec:
  containers:
  - name: ubuntu
    image: ubuntu
    command: [ "/bin/bash", "-ce", "tail -f /dev/null" ]
