Installation

Recommended (via agent helm chart)

All extensions provide a helm chart that is also integrated in the helm-chart of the agent.

You must provide additional values to activate this extension.

--set extension-k6.enabled=true \

If you want to use K6 Cloud you need to provide a k6 cloud api token. You can add it for example with --set extension-k6.k6.cloudApiToken="111-222-333"

Additional configuration options can be found in the helm-chart of the extension.

Alternative (via own helm chart)

If you need more control, you can install the extension via its dedicated helm-chart.

Extension registration

Make sure that the extension is registered with the agent. In most cases this is done automatically. Please refer to the documentation for more information about extension registration and how to verify.

Proxy

To communicate to K6 Cloud via a proxy, we need the environment variable https_proxy to be set. This can be set via helm using the extraEnv variable

--set "extraEnv[0].name=HTTPS_PROXY" \
--set "extraEnv[0].value=https:\\user:pwd@CompanyProxy.com:8888"
