Kubernetes Node Not Ready? Here’s What to Check First

Seeing a NotReady node can impact pod scheduling and cluster stability.

Steps to Fix:

1. Check node status: kubectl get nodes
2. SSH into the node:
   • Run systemctl status kubelet
   • Check disk space: df -h
   • Inspect network: is DNS working?
3. Use: journalctl -u kubelet to see kubelet errors.

Resolution:

• Restart kubelet or the node VM
• Clear disk if full
• Reconfigure cloud provider settings (e.g., IAM roles, security groups)
