I am deploying Locust on Kubernetes using Helm Charts(https://github.com/helm/charts/tree/master/stable/locust)
2 Worker pods are running with no errors, but master is in CrashLoopBackOff status.
When I check the logs for the failing pod I see following error:

I will appreciate if someone could help me understand what I am doing wrong. My thought was that I am using HttpUser and in the image that I am pulling (greenbirdit/locust) the is still LocustUser, but I don't know how to fix it.
Thank you for help!
Your link to Locust Helm Chart says it's using Locust container 0.9.0. Before Locust 1.0 HttpUser was HttpLocust. You can see the documentation for 0.9.0 here: https://docs.locust.io/en/0.9.0/
I don't use Helm, but it sure looks like you'll want to rewrite your locustfile to use HttpLocust and other pre-1.0 APIs until Helm updates the chart to use 1.0+.
