kubelet 启动失败failed to build map of initial containers from runtime no Podsand
kubelet 启动失败，报错为：failed to build map of initial containers from runtime: no PodsandBox found with Id ‘d08297f6a1a3c25c88c6155005778e36be90b8919383c88dfe22b7313a984d89’
详细如下：
May 31 19:36:53 sh-saas-k8s1-node-qa-52 kubelet: Flag --logtostderr has been deprecated, will be removed in a future release, see https://github.com/kubernetes/enhancements/tree/master/keps/sig-instrumentation/2845-deprecate-klog-specific-flags-in-k8s-components

主要是找不到runtime内对应ID的容器，id为’d08297f6a1a3c25c88c6155005778e36be90b8919383c88dfe22b7313a984d89′
解决办法：
通过下面的命令找到容器id:
docker ps -a --filter "label=io.kubernetes.sandbox.id=d08297f6a1a3c25c88c6155005778e36be90b8919383c88dfe22b7313a984d89"
再删除容器：
docker rm ID
如果找不到容器ID了，可以：
- 踢掉节点,停掉kubelet:
systemctl stop kubelet - 删除所有容器:
docker rm $(docker ps -a -q) - 使用
docker system prune -a -f --volumes清理容器 - 重启kubelet
