8.Pod的状态和探针
https://kubernetes.io/zh/docs/concepts/workloads/pods/pod-lifecycle/
8.1 Pod状态
第一阶段:
Pending:
#正在创建Pod但是Pod中的容器还没有全部被创建完成,处于此状态的Pod应该检查Pod依赖的存储是否有权限挂载、镜像是否可以下载、调度是否正常等。
Failed
#Pod中有容器启动失败而导致pod工作异常。
Unknown
#由于某种原因无法获得pod的当前状态,通常是由于与pod所在的node节点通信错误。
Succeeded
#Pod中的所有容器都被成功终止即pod里所有的containers均已terminated。
第二阶段:
Unschedulable:
#Pod不能被调度,kube-scheduler没有匹配到合适的node节点
PodScheduled
#pod正处于调度中,在kube-scheduler刚开始调度的时候,还没有将pod分配到指定的pid,在筛选出合适的节点后就会更新etcd数据,将pod分配到指定的pod
