In Kubernetes, particularly with Traefik ingress, several factors can cause connectivity issues. Key points include verifying whether the pod is running, checking if the service and port are correctly exposed, and confirming that Traefik routes traffic properly. There can be complexities when using a single Traefik instance for multiple namespaces. Access logs, while informative, can be overwhelming due to the volume of errors, and essential details about source and destination IP addresses are often found in logs. Tools like curl and telnet can assist in checking connectivity from within pods.
When experiencing issues with Kubernetes services and Traefik ingress, ensure the pod is running, verify service and port configurations, and confirm Traefik's ability to route traffic accurately.
Deploying Traefik with Helm in a single namespace allows access to ingress routes across all namespaces, but this might introduce complexity in routing configuration.
Analyzing access logs can be challenging due to verbosity, yet crucial details like source host IPs and error messages indicate where traffic issues may arise.
Troubleshooting connectivity can begin with checking pod status in the namespace, and further network diagnostics can be performed using tools like curl or telnet.
