## Selenium on Kubernetes
Selenium is a browser automation tool used primarily for testing web applications. However when Selenium is used in a CI pipeline to test applications, there is often contention around the use of Selenium resources. This example shows you how to deploy Selenium to Kubernetes in a scalable fashion.
### Prerequisites
This example assumes you have a working Kubernetes cluster and a properly configured kubectl client. See the [Getting Started Guides](https://kubernetes.io/docs/getting-started-guides/) for details.
Google Container Engine is also a quick way to get Kubernetes up and running: https://cloud.google.com/container-engine/
Your cluster must have 4 CPU and 6 GB of RAM to complete the example up to the scaling portion.
### Deploy Selenium Grid Hub:
We will be using Selenium Grid Hub to make our Selenium install scalable via a master/worker model. The Selenium Hub is the master, and the Selenium Nodes are the workers(not to be confused with Kubernetes nodes). We only need one hub, but we're using a replication controller to ensure that the hub is always running:
```console
kubectl create --filename=staging/selenium/selenium-hub-deployment.yaml
```
