Getting Started Tutorial: Debug Reaction in GitHub Codespaces setting shows 404 due to ingress host header mismatch #194
Description
Issue:
Following the step 4 of Getting Started guide on Drasi website, under the GitHub Codespaces setup, noticed that the browser is showing 404 page not found.
Details:
The port-forward on 8080 is pointing at the traefik ingress controller, and the ingress expects the host header hello-world-debug.drasi.127.0.0.1.nip.io. But when I access it via the Codespaces URL, the host header is congenial-fishstick-...app.github.dev, which doesn't match — so traefik returns 404.
$ kubectl get svc -n drasi-system | grep hello-world-debug

Kill the traefik port-forward and port-forward directly to the gateway service:
kubectl port-forward svc/hello-world-debug-gateway 8080:8080 -n drasi-system
Suggested fix:
Update the setup script to port-forward to the gateway service instead of traefik, or document this (at _index.md) as a known issue.
Happy to submit a PR to fix this :)
