kubernetes - 在Kubernetes中运行蝗虫时无法从 'HttpUser'错误导入名称 'locust'

Question

我正在使用Helm Charts(https://github.com/helm/charts/tree/master/stable/locust)在Kubernetes上部署蝗虫
2 Worker Pod正在运行，没有错误，但是master处于CrashLoopBackOff状态。
当我检查失败的Pod的日志时，看到以下错误:

如果有人可以帮助我了解我在做什么错，我将不胜感激。我的想法是我使用的是 HttpUser，并且在我拖动的图像(greenbirdit /蝗虫)中仍然是 LocustUser，但是我不知道如何解决。
谢谢你的帮助!

您到Locust Helm Chart的链接说它正在使用Locust容器0.9.0。在Locust 1.0之前，HttpUser是HttpLocust。您可以在此处查看0.9.0的文档:https://docs.locust.io/en/0.9.0/
我没有使用Helm，但可以肯定的是，您似乎要重写locustfile以使用HttpLocust和其他1.0之前的API，直到Helm将图表更新为使用1.0+。
