Developed a configurable replicas feature for Selenium Grid within the SeleniumHQ/docker-selenium repository, focusing on enhancing scalability and availability in Kubernetes environments. Leveraged Helm and Kubernetes, working primarily with YAML, to enable per-component replica counts and enforce a minimum of one replica per deployment. Updated deployment templates and configuration documentation to support flexible scaling and align with high-availability best practices. The work addressed the need for dynamic resource allocation in containerized Selenium Grid deployments, allowing users to tailor replica counts for each component. This feature improved operational flexibility and reliability for teams running Selenium Grid on Kubernetes clusters.
