How do i programatically determine whether a pod is in crashloopbackoff
问题
有没有办法通过编程确定一个 pod 是否处于 crashloopbackoff 状态？
我尝试了以下代码：
pods, err := client.CoreV1().Pods(namespace).List(context.TODO(), metav1.ListOptions{})
if err != nil {
return err
}
for _, item := range pods.Items {
log.Printf("found pod %v with state %v reason %v and phase %v that started at %v",
item.Name, item.Status.Message, item.Status.Reason, item.Status.Phase, item.CreationTimestamp.Time)
}
然而，这只会打印出状态和原因为空，但会打印出阶段信息。

I tried the following
pods,err := client.CoreV1().Pods(namespace).List(context.TODO(), metav1.ListOptions{})
if err != nil {
return err
}
for _, item := range pods.Items {
log.Printf("found pod %v with state %v reason %v and phase %v that started at %v",
item.Name, item.Status.Message, item.Status.Reason, item.Status.Phase, item.CreationTimestamp.Time)
}
However this just prints blank for state and reason, tough it prints the phase.

kubectl get po -o jsonpath='{.items[*].status.containerStatuses[*].state.waiting.reason}'
>需要注意的是，它只会间歇性地显示在那里，因为它是容器的间歇性状态；也许更加程序化的方法是检查restartCount和Error状态。

kubectl get po -o jsonpath='{.items[*].status.containerStatuses[*].state.waiting.reason}'
