knative-proxy

A node.js proxy for invoking Knative services on behalf of XHRs. This code exists because Knative by default requires a certain value in the HOST header. That value by default is servicename.namespace.example.com. Unfortunately, XHRs aren't allowed to set the HOST header value, so they can't access Knative services.

This repo is part of an interactive Knative and serverless tutorial, the Compile Driver, a ride at an imaginary theme park called Coderland.

Environment variables

There are three environment variables you can set when you run npm start:

  1. PORT - the port number for the service. Default is 8888.
  2. PROXY_URL - The URL for the Knative cluster. Default is http://192.168.99.100:31380/overlayImage.
  3. PROXY_HOST - The value for the HOST header. Default is overlayimage.knativetutorial.example.com.nip.io.
