Windows节点上使用logtail

环境要求

• 创建Linux托管集群，添加OS为Windows的节点池来使用Windows节点
• 集群已经部署了日志组件

添加Windows节点的logtail

• 在kube-system下的configmap alibaba-log-configuration中添加item

win-log-config-path: C:\Program Files (x86)\Alibaba\Logtail\conf\ap-southeast-1\ilogtail_config.json

• 部署Windows节点的daemonset

目前logtail仅限于支持采集stdout的输出至日志服务，后续会支持对日志文件的采集

部署完成后可以使用如下应用去验证是否可用：
