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
