To troubleshoot connectivity issues with new services in Kubernetes using Traefik, systematically check the status of pods and services, ensuring they are both running and correctly configured. Use logs to diagnose errors, keeping in mind that too many errors may complicate troubleshooting. It's beneficial to deploy a network-checking pod within the same namespace to validate connectivity. Issues can range from pod failures to misconfigured routing rules and exposed ports. Monitoring Traefik not only helps in managing ingress but also aids in identifying where traffic is misrouted or blocked.
First, check if the pod is running properly using 'kubectl get pod -n <namespace>'. Then create a pod in the same namespace for further networking checks.
Evaluating the traffic path through Traefik is crucial, as errors may arise from wrong routing rules or exposed ports that hinder direct communication.
