This chart bootstraps a private WebPageTest Server deployment on a Kubernetes cluster using the Helm package manager.
Depending on your configuration you can then use Official WPT agent instances to test your websites.
This chart provides support for ingress resources. If you have an ingress controller installed on your cluster, such as nginx-ingress or traefik you can utilize the ingress controller to service your WebPageTest application.
To enable ingress integration, please set ingress.enabled to true.
Most likely you will only want to have one hostname that maps to this WebPageTest installation for scripts or end users to interact, then a separate instance for the AMI’s to operate on (see AgentIngress below). It is, however, possible to have more than one host. To facilitate this, the ingress. hosts object is an array.
For each item, please indicate a name, tls, tlsSecret, and any annotations that you may want the ingress controller to know about.
Indicating TLS will cause WebPageTest generate HTTPS urls, and WebPageTest will be connected to at port 443. The actual secret that tlsSecret references does not have to be generated by this chart. However, please note that if TLS is enabled, the ingress record will not work until this secret exists.
For annotations, please see this document. Not all annotations are supported by all ingress controllers, but this document does a good job of indicating which annotation is supported by many popular ingress controllers.
This chart will facilitate the creation of TLS secrets for use with the ingress controller, however, this is not required. There are three common use cases:
helm generates / manages certificate secrets
user generates / manages certificates separately
an additional tool (like kube-lego) manages the secrets for the application
Generally speaking WebPageTest is difficult to secure / restrict access. In creating this chart the design is that a user would use the ingress listed above. The ingress above would have appropriate access restrictions using either whitelisted IP’s, http basic auth or both. This however would block access to the agents without significant additional config. Agents in a remote region would probably need a region to region VPN to get access. Rather than doing that we create a second host header and restrict the url path to /work, /cron and /jpeginfo. The agents use /work and the server connects to itself on /cron and /jpeginfo. This way 3rd parties do not have access to create tests, but any host (with the correct keys) can get work units and post results.
