Selenium Grid Docker Images Are Now Mirrored to GHCR

Sat, 04 Apr 2026 00:00:00 +0000

The request started with a simple question in issue #2939: can we publish Selenium Grid Docker images to GitHub Container Registry as well as Docker Hub?

The answer is now yes.

Official Selenium Grid Docker images are now available from GitHub Container Registry (GHCR) under:

ghcr.io/seleniumhq

This is a mirror, not a replacement. Docker Hub remains available, and existing users do not need to change anything. But if your environment prefers GHCR, blocks Docker Hub, or simply wants another official source for the same images, you now have one.

Selenium Grid 4.41.0: What's New and Why It Matters

Sun, 22 Feb 2026 00:00:00 +0000

We are excited to ship Selenium Grid 4.41.0 🎉 — and this might be one of impactful releases in recent memory. Whether you are running Grid in a bare-metal lab, a Docker Compose stack, or a sprawling Kubernetes cluster, this release brings something meaningful for you. From a brand-new Dynamic Grid for Kubernetes, a powerful Session Event API, to smarter video recording and a rock-solid Distributor, let’s dig in.

1. Dynamic Grid, Now Native on Kubernetes

The headline feature of 4.41.0 is unambiguous: Dynamic Grid now runs natively inside Kubernetes clusters (selenium#17092, docker-selenium#3082).

Multi-Arch Images via Docker Selenium

Thu, 23 May 2024 00:00:00 +0000

We’re very happy to announce the landing of Multi-Arch Images for Selenium Grid Server on the Selenium Docker Hub registry!

Motivation

For experimental Docker container images that are able to run on platforms such as the Apple M-series or Raspberry Pi, the community-driven repository initiative hosted at SeleniumHQ-Community/docker-seleniarm. These images are built for separate architectures: linux/arm64 (aarch64), linux/arm/v7 (armhf), and linux/amd64 and published on Seleniarm Docker Hub registry.

In order to bring more awareness to the existence of the Multi-Arch Docker container images, provide more insight and transparency on how the container images are built, as well as overcome challenges in building and maintaining them. We have decided to merge the fork into the main project Docker Selenium and published multi-arch images on Selenium Docker Hub registry.

Dev and Beta Channel Browsers via Docker Selenium

Tue, 23 Aug 2022 00:00:00 +0000

The Docker Selenium browser Beta and Dev channel releases are now regularly published to Docker Hub and updated every two days. This enables testers and developers to test their applications on pre-release versions of Google Chrome, Mozilla Firefox, and Microsoft Edge before their official releases, using container tools, such as Docker. This empowers teams to stay ahead of the curve and catch potential showstoppers in their CI environment before those issues have an impact on their users.
