whoami (echo server)

A tiny page that shows what the request looked like.

About

A tiny page that shows what the request looked like. The smallest possible test that a domain, certificate and routing all work.

Notes

Tiny HTTP server (traefik/whoami) that returns the request headers, client IP and container hostname. Used as the smallest possible sanity-check for the v2 install pipeline and for Caddy ingress binding — bind a domain to it and curl the response to verify TLS, routing and DNS in one shot.

Run it on your own hardware.

Obacht is in a closed pilot phase. Put yourself on the list. We let people in a few at a time, so it can take a while.
