How do I troubleshoot Calico networking issues?

I'm having trouble with Calico networking in my Kubernetes cluster. What should I check first?

First, check the Calico pods' status using kubectl get pods -n kube-system. Ensure all pods are running.

Some pods are in a CrashLoopBackOff state. What does that mean?

A CrashLoopBackOff indicates that a pod is failing to start repeatedly. Check the pod logs with kubectl logs <pod-name> -n kube-system for errors.

I see an error about IP address conflicts. How can I resolve that?

IP address conflicts can occur if multiple nodes are trying to use the same IP. Ensure your IP pool is correctly configured and that no overlapping CIDRs exist.

Thanks! What if I need to reset the Calico configuration?

You can reset Calico by deleting the Calico resources and reapplying the configuration files. Make sure to back up any important settings first.
