This chart enables the creation of a Selenium Grid Server in Kubernetes.
If you want to install the latest master version of Selenium Grid onto your cluster you can do that by using the helm charts repository located at https://www.selenium.dev/docker-selenium.
# Add docker-selenium helm repository
helm repo add docker-selenium https://www.selenium.dev/docker-selenium
# Update charts from docker-selenium repo
helm repo update
# List all versions present in the docker-selenium repo
helm search repo docker-selenium --versions
# Install basic grid latest version
helm install selenium-grid docker-selenium/selenium-grid
# Or install full grid (Router, Distributor, EventBus, SessionMap and SessionQueue components separated)
helm install selenium-grid docker-selenium/selenium-grid --set isolateComponents=true
# Or install specified version
helm install selenium-grid docker-selenium/selenium-grid --version 0.3.0Once you have a new chart version, you can update your selenium-grid running:
helm upgrade selenium-grid docker-selenium/selenium-gridTo uninstall:
helm uninstall selenium-gridFor now, global configuration supported is:
