Nothing unexpected. That zoo story was weird.

We can test webhook callbacks with a little http server and a localtunnel.

Run server.js to spin up a local http server on port 8080. It just exposes a top-level route and will print the received header and payload of any request. Then create a localtunnel to have a non-local url that proxies all requests to localhost:8080.

---

First, install dependencies with npm install.

Then start the express server with npm start.

$ kube-proxy --help
The Kubernetes network proxy runs on each node. This
reflects services as defined in the Kubernetes API on each node and can do simple
TCP,UDP stream forwarding or round robin TCP,UDP forwarding across a set of backends.
Service cluster ips and ports are currently found through Docker-links-compatible
environment variables specifying ports opened by the service proxy. There is an optional
addon that provides cluster DNS for these cluster IPs. The user must create a service
with the apiserver API to configure the proxy.
