Kubernetes (K8S) works wonders for scaling up and down applications based on their CPU and Memory usage, but it is not so straightforward when it comes down to applications like Selenium Grid.

The issue is described quite well in this blog post. But in short, the Horizontal Pod AutoScaler (HPA) that is built into Kubernetes checks (by default) for resource consumption to determine if a deployment needs to be scaled up or down. This becomes an issue for Selenium Grid for a couple reasons:
