无法启动 busybox pod

如果我像这样启动 Kubernetes pod，它会失败：

k run bb --image=busybox

k describe pod bb

...
Events:
  Type     Reason   Age                     From     Message
  ----     ------   ----                    ----     -------
  Normal   Pulling  14m (x35 over 164m)     kubelet  Pulling image "busybox"
  Warning  BackOff  4m23s (x736 over 164m)  kubelet  Back-off restarting failed container

是什么原因？

该run命令对于图像来说运行良好nginx。

答案1

busybox不是服务器。它不会启动无休止的“监听输入”循环。

对于图像来说也是同样的情况alpine。

但你可以创建一个像这样的无限循环：

apiVersion: v1
kind: Pod
metadata:
  name: bb
spec:
  containers:
  - image: busybox
    command: ['sh', '-c', 'while true; do date; sleep 3; done']
    name: bb

k apply -f bb.yaml

k describe pod bb

...
Events:
  Type    Reason     Age   From               Message
  ----    ------     ----  ----               -------
  Normal  Scheduled  6s    default-scheduler  Successfully assigned default/bb to minikube-m02

  Normal  Created    3s    kubelet            Created container bb
  Normal  Started    3s    kubelet            Started container bb

您可以看到日志：

guettli@p15:~/.kube$ k logs bb
