Quick Start

Kubernetes (K8s) orchestrates clusters of machines running containers. It declarative states (YAML) to manage Deployments, Services, and Ingresses.

kubectl apply -f deployment.yaml

Production Patterns

Operators

For complex stateful applications (like Postgres or Redis), do not manually manage StatefulSets. Use Kubernetes Operators (e.g., CrunchyData Postgres Operator) to handle backups, failovers, and version upgrades automatically.

Architecture & Scaling

Probes

Always define livenessProbe and readinessProbe. The liveness probe determines if the pod needs to be restarted. The readiness probe determines if the pod is ready to receive network traffic from the Service load balancer.

Error Recovery

If pods frequently crash with OOMKilled (Out of Memory), ensure your resources.limits.memory is set correctly and matches the memory allocation limits of your runtime (e.g., Node.js --max-old-space-size).

Security Notes

Enable RBAC (Role-Based Access Control). Do not grant default Service Accounts cluster-admin privileges. Utilize Network Policies to restrict pod-to-pod communication (e.g., only the backend can talk to the database).

Why use this skill

Use this when your agent works with kubernetes — structured patterns beat pasted docs and prevent common hallucinations.

AI pitfalls

• Referencing CLI flags or config keys that do not exist
• Using outdated major versions of tools
• Skipping lockfile or version pinning in examples

Production checklist

• [ ] Secrets in environment variables, not source code
• [ ] Error handling and logging in place
• [ ] Rate limits and timeouts configured
