This chart enables the creation of a Selenium grid server in Kubernetes.
To install the selenium-grid helm chart, you can run:
# Clone the project
git clone https://github.com/seleniumhq/docker-selenium.git
# Install basic grid
helm install selenium-grid docker-selenium/chart/selenium-grid/.
# Or install full grid (Router, Distributor, EventBus, SessionMap and SessionQueue components separated)
helm install selenium-grid --set isolateComponents=true docker-selenium/chart/selenium-grid/.Once you have a new chart version, you can update your selenium-grid running:
helm upgrade selenium-grid docker-selenium/chart/selenium-grid/.To uninstall:
helm uninstall selenium-gridFor now, global configuration supported is:
