説明

Feature and motivation

Currently when running Selenium Grid in Kubernetes via the Helm-chart, the hub becomes unreachable when deploying changes. This is due to there only being one replica.

Given multiple replicas, a rollout will keep the hub reachable during a deploy.

Usage example

Having multiple replicas will make the Grid more robust.

調査方針: Review the existing Helm chart configuration in the repository, particularly the values.yaml and templates/deployment.yaml files. Look for comments in this issue (#1849) discussing how to implement multiple replicas and any maintainer feedback. Consider the need for leader election or session persistence when running multiple Hub pods. Test with a simple replica count change in your Kubernetes cluster.
