@MahmoudDolah well something in the chain is setting the port to an invalid number. https://github.com/GoogleChrome/lighthouse-ci/pull/270 should add more debug information to help track it down.

Okay I have found out the issue here @patrickhulce. The system documented in Kubernetes doesn’t take into account a deployment or a service being attached (this is how we would set up a Kube system). In the situation of an lhci server we would define:

A deployment with LHCI container
A service linking to the LHCI container
An ingress connected to such service

In the kubernetes world, a service linked to a deployment automatically creates SERVICE_PORT and SERVICE_HOST ENV vars. This means if your service is named lhci then the env vars filtered down are LHCI_PORT=tcp://.... This is the issue people are encountering above.

Should we amend the documentation to highlight this clash?
