阿里云k8s应用最新日志采集不到的问题

问题描述：阿里云k8s应用日志之前一直都是可以正常的采集，先出现一问题，通过kibana 和阿里云的日志服务都没法展示最新的k8s应用的日志，部分应用的最新日志有被采集到，但大部分应用日志没有做采集到。

通过 命令 curl '17*****0:9200/_cat/indices?v'   查看 
 
部分应用没有建立今天的日志索引

删除了elasticsearch组件，再重新安装以后，问题依然存在

通过  
 kubectl delete DaemonSet log-pilot -n kube-system 
   kubectl delete DaemonSet logtail-ds  -n kube-system 
 
删除了日志采集工具 log-pilot, logtail 后再尝试重新安装

重新安装 log-pilot组件 
 
kubectl apply -f https://acs-logging.oss-cn-hangzhou.aliyuncs.com/log-pilot.yml
daemonset.extensions/log-pilot created<br>

kubectl get DaemonSet -n kube-system 
NAME                       DESIRED   CURRENT   READY     UP-TO-DATE   AVAILABLE   NODE SELECTOR                     AGE

kube-flannel-ds            6         6         6         6            6           beta.kubernetes.io/arch=amd64     76d
kube-proxy-master          3         3         3         3            3           node-role.kubernetes.io/master=   76d
kube-proxy-worker          3         3         3         3            3           <none>                            76d
log-pilot                  6         6         6         6            6           <none>                            3s

再次通过命令查看日志索引 ， 已经可以看到最新的应用日志索引
 
 curl '172.21.7.210:9200/_cat/indices?v'

重新安装 logtail  组件
