背景

刚写asm项目时，爬虫服务是通过service对外提供服务。

爬虫服务容器编排yaml文件见 https://github.com/leveryd-asm/asm/blob/f6c481efbe/templates/crawler.yaml

工作流中调用服务的例子见 https://github.com/leveryd-asm/asm/blob/f6c481efbe5820fb682bc1dc4113ec168cd2275e/templates/argo-workflow-template/argo-workflow-atom-template-crawler.yaml

但现在工作流中直接调用爬虫二进制文件

背景

中间有一段时间没有数据

如果重启proxify pod，es就会又有数据。就像图中那样

为什么会这样？
