Selenium grid is setup using 4 files

They can be run using the following commands

kubectl create --filename=examples/selenium-hub-deployment.yaml
watch -n 1 kubectl get pods # wait for the selenium hub pod to be in Running state
kubectl create --filename=examples/selenium-hub-svc.yaml
kubectl create --filename=examples/selenium-node-chrome-deployment.yaml
kubectl create --filename=examples/selenium-node-firefox-deployment.yaml
watch -n 1 kubectl get pods # wait for the selenium firefox and chrome pods to be in Running state. The necessary containers are fetched from the registry if required

Miscellaneous

By now, the selenium hub and the associated nodes should be up and running. The selenium hub runs on one of the nodes. To identify the hub url, run the following on the shell:

NODENAME=`kubectl get pod -ojsonpath='{.items[0].spec.nodeName}' -lapp=selenium-hub`
NODEPORT=`kubectl get svc selenium-hub -ojsonpath="{.spec.ports[0].nodePort}"`
echo "http://$NODENAME:$NODEPORT/grid/console"  # this is the selenium grid URL
