This repository provides Docker images and Kubernetes Helm charts for deploying Selenium Grid, the industry-standard browser automation framework. It covers all major browser backends (Chrome, Firefox, Edge, Chromium) and supports multiple deployment modes: standalone single-container, hub-and-node, fully distributed grid, and dynamic grid with Docker-in-Docker or Kubernetes backends. The architecture follows a microservice pattern where each Grid component (Router, Distributor, Session Queue, Nodes, etc.) runs in its own container, orchestrated by supervisord. Beyond core Grid images, the repo includes a comprehensive monitoring stack with a Go-based Prometheus exporter that scrapes the Grid GraphQL endpoint, pre-built Grafana dashboards, and a KEDA external scaler for Kubernetes native autoscaling. Video recording and upload services are provided as sidecar containers, with both event-driven (ZeroMQ) and polling-based implementations. The CI/CD pipeline is extensive, with GitHub Actions workflows for building multi-architecture images (amd64/arm64), running integration tests, scanning for vulnerabilities, and publishing to Docker Hub and GHCR. The codebase is well-tested with unit tests for Go components, Python integration tests for autoscaling, and Java/Playwright browser tests. Despite its complexity, the repository demonstrates solid engineering practices with clear separation of concerns, reusable shell libraries, and automated dependency management via Renovate and Dependabot.
