Selenium

MAINTENANCE NOTICE

• [2021-03-12] This chart is cloned from a deprecated chart at Stable Helm repo, and continued developing by LogiGear EPG Dept. Since Selenium 4 is still under beta phase and not ready for production yet, this would help any of us, who want to have a "Helm way" to deploy Selenium 3 Grid to Kubernetes Cluster.

TL;DR;

$ helm repo add ta-chart https://chart.testarchitect.com
$ helm repo update
$ helm install my-grid ta-chart/selenium3

Introduction

This chart bootstraps a Selenium 3 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-grid:

$ helm repo add ta-chart https://chart.testarchitect.com
$ helm repo update
$ helm install my-grid ta-chart/selenium3

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-grid deployment:

$ helm delete my-grid

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 my-grid \
  --set chrome.enabled=true \
  ta-chart/selenium3

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

$ helm install my-grid -f values.yaml ta-chart/selenium3

Tip: You can use the default values.yaml
