Windows節點上使用logtail

環境要求

• 創建Linux託管集羣，添加OS爲Windows的節點池來使用Windows節點
• 集羣已經部署了日誌組件

添加Windows節點的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節點的daemonset

目前logtail僅限於支持採集stdout的輸出至日誌服務，後續會支持對日誌文件的採集

部署完成後可以使用如下應用去驗證是否可用：
