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/selenium3Introduction
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/selenium3The 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-gridThe 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/selenium3Alternatively, 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/selenium3Tip: You can use the default values.yaml
