The karrot-frontend nginx template hardcodes Docker's DNS resolver (127.0.0.11) which doesn't exist in Kubernetes. Added a ConfigMap to override the template, removing the Docker DNS resolver by using a direct proxy_pass with no nginx variable (which would force runtime resolution). Also adds a README with usage instructions. Documents lessons learned in ADDING-APPS-NOTES.md: - Note 24: nginx Docker DNS resolver doesn't work in Kubernetes; any nginx variable in proxy_pass (including $request_uri) forces runtime DNS resolution requiring a resolver directive - Note 25: ConfigMap changes don't restart pods; subPath mounts never auto-update; always follow with kubectl rollout restart - Note 26: includeSelectors mismatch affects every deployment in an app — check all endpoints, not just the web-facing one Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
