Description

What happened?

Hi all!
I have been trying to deploy selenium grid via helm chart v0.33.0 and noticed high level of workload memory usage.
In this case, azure runs autoscaling and adds a second machine to kubernates when we run tests.

I loaded selenium using kubernates helm chart by changing the following parameters:

  • isolateComponents=true (for full services Router, Distributor, EventBus, SessionMap and SessionQueue, ...)
  • tls
  • 1 node for each browser (chrome, edge, ff)
  • INFO log level
  • basic authenticator true
  • other params by default
  • I remove the resource request and limit after deployment(browsers)

kubernates version 1.29.5
chart 0.33.0
selenium images latest

It's probably not a defect, but I need to figure out what's going wrong.
Thanks!

Research direction

Start by reproducing the documented helm install with isolateComponents=true, the stated Kubernetes, chart, and image versions, and the listed component settings. Inspect memory usage for each resulting workload and compare it with the reported autoscaling behavior; done means identifying an evidence-backed cause or confirming that more diagnostics are needed.
