Selenium

TL;DR;

$ helm install stable/selenium

Introduction

This chart bootstraps a Selenium deployment on a Kubernetes cluster using the Helm package manager.

Prerequisites

• Kubernetes 1.5+ with Beta APIs enabled

Installing the Chart

To install the chart with the release name my-release:

$ helm install --name my-release stable/selenium

The command deploys Selenium on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.

Tip: List all releases using helm list

Uninstalling the Chart

To uninstall/delete the my-release deployment:

$ helm delete my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

$ helm install --name my-release \
  --set chrome.enabled=true \
    stable/selenium

Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,

$ helm install --name my-release -f values.yaml stable/selenium

Tip: You can use the default values.yaml
