Kubespray Troubleshooting

Overview

Diagnose and fix common Kubespray deployment failures. Most failures stem from network misconfiguration, etcd issues, or stale state from previous attempts.

Core principle: Read the exact task name that failed, check logs on that specific node, then fix and re-run (Ansible is idempotent).

When to Use

• Deployment fails mid-playbook
• kubeadm join errors
• etcd health check timeouts
• Nodes stuck in NotReady state
• Certificate-related failures

Not for: Initial deployment setup (use kubespray-deployment), upgrades (use kubespray-operations), certificate renewal (use kubespray-certificates)
