Optimizely Agent Helm Chart

This repository contains a Helm chart to make it easy to host Optimizely Agent in your own Kubernetes infrastructure. The Optimizely Agent allows you to run a proxy to Optimizely in your own infrastructure, to help prevent adblockers from interfering with A/B tests.

Installation

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

helm repo add optimizely-agent https://optimizely.github.io/optimizely-agent-helm
helm install my-agent optimizely-agent/agent

Modifying values

• To override values in a chart:
  • use the --values flag and pass in a file.
  • use the --set flag and pass configuration from the command line.
• Use the --set-file flag to set individual values from a file when the value itself is too long for the command line or is dynamically generated.
• To force a string value use --set-string.

For example:

helm install --values myvalues.yaml my-agent optimizely-agent/agent --version [CURRENT_VERSION]

or

helm install --set nameOverride=abc123 my-agent optimizely-agent/agent --version [CURRENT_VERSION]

For more information, view the Helm install documentation or install through Artifact Hub.

Uninstalling the Chart

To uninstall/delete the my-agent deployment:

helm delete my-agent
