Has someone tried HPA for selenium node. I not able to scale up as the CPU consumption is very low.
What does HPA mean in the context of Selenium node?
I did try and you can see my talk here - https://www.slideshare.net/aragavan/selenium-grid-based-on-kubernetes-docker-traefik-and-helm (slides 19-21) but not yet 100% successful. My issue is, Kubernetes still not able to get the mertics even though metrics server is running fine. @russel
Hi Nice Article. But How do I scale Selenium HUB because that is single point of failure.
While Selenium Hub is a single-point-of-failure, the recovery time of a failure is almost instant because Kubernetes will schedule a replacement container right away.
Sometimes removing a single-point-of-failure results in a more confusing and difficult to operate system. I didn't want to take on that risk.
In my situation, I had no need for HA (high availability) because the mean-time-to-recovery of a Selenium Hub is so fast and without any real consequence.
I think you should review your requirements to see if you really need a HA Hub.
