Description

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.

Contributor guide

Research direction
Examine the Helm chart for Selenium Grid, understand the current deployment config for the hub, and implement support for multiple replicas with leader election or stateless design.
