我正在运行Argo工作流，并在pod的日志中得到以下错误：
error: a container name must be specified for pod <name>, choose one of: [wait main]
这个错误只在某些时候发生，而且只发生在我的一些模板上，但当它发生时，它是工作流中稍后运行的模板(即不是第一次运行模板(。我还没有能够确定将成功运行的参数，所以我会很乐意提供调试技巧。我已经粘贴了下面描述的输出。
基于搜索，我认为解决方案很简单，我需要附加"-"c主"；在某个地方，但我不知道在哪里，也无法在Argo文档中找到信息。

当您试图查看具有多个容器的pod的日志，而没有指定要查看日志的容器时，就会发生这种情况。查看日志的典型命令：
kubectl logs <podname>
但你的Pod有两个容器，一个名为"；等待"；以及一个名为"；主要"；。您可以从名为"的容器中看到日志；主"；带有：
kubectl logs <podname> -c main
或者你可以看到所有带有的容器的日志
kubectl logs <podname> --all-containers
