|---|---|
| Cluster Creation | Build a production-ready cluster with initial baseline settings |
| Node Pool Operations | Add, scale, cordon, drain, and retire node pools safely |
| Upgrades | Upgrade Kubernetes versions and node images with validation |
| Scaling Operations | Operate HPA, VPA, and cluster autoscaler safely |
| Monitoring and Logging | Configure observability, alerts, and diagnostic collection |
| Maintenance Windows | Align upgrades and platform maintenance with business windows |
| Credential Rotation | Rotate certificates, identities, kubeconfig access, and secrets |
Advanced Topics¶
- Treat every operational change as a runbook with pre-checks and post-checks.
- Keep non-production clusters close enough to production that upgrades and scaling tests are meaningful.
