This folder contains information and tools for debugging the Kubernetes node agent (kubelet).

1. Check Kubelet Logs:

   • Use journalctl -u kubelet to view logs on the node.
   • Look for errors related to pod creation, health checks, or resource usage.

2. Verify Node Health:

   • Run kubectl get nodes to check the status of nodes.
   • Use kubectl describe node <node-name> for detailed information.

3. Inspect Pod Status:

   • Use kubectl get pods -o wide to check pod status and node assignment.
   • Use kubectl describe pod <pod-name> for more details.

4. Check Resource Usage:

   • Use tools like top or htop on the node to monitor CPU and memory usage.

5. Inspect Configuration:

   • Review the kubelet configuration file (e.g., /var/lib/kubelet/config.yaml).

• kubectl
• journalctl
• Node monitoring tools like top, htop, or nmon.

Problem: Pods are not starting on a node.

Solution:

1. Check kubelet logs: journalctl -u kubelet.
2. Verify node status: kubectl get nodes.
3. Inspect pod events: kubectl describe pod <pod-name>.
4. Check resource availability on the node: top or htop.
