Ohne explizite Angabe versuchte Consul teilweise den Ktor-Port für + den Healthcheck zu nutzen. +2. **Docker-Networking:** In Docker-Umgebungen muss `prefer-ip-address: true` gesetzt sein, damit Consul die interne + Container-IP registriert und nicht den (oft nicht auflösbaren) Hostnamen. +3. **Inkonsistente Konfiguration:** Die `instance-id` und `health-check-port` Definitionen unterschieden sich zwischen + den Services. + +## 2.
