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

　　

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

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 


helm del --purge alibaba-log-controller
release "alibaba-log-controller" deleted
