Kubernetes Best Practices for Production

Kubernetes is powerful but complex. Misconfigurations can lead to security vulnerabilities and downtime.

Resource Limits

Always set CPU and memory requests and limits for your containers. This prevents a single runaway container from starving the entire node.

resources:
  requests:
    memory: "64Mi"
    cpu: "250m"
  limits:
    memory: "128Mi"
    cpu: "500m"

Health Checks

Configure Liveness and Readiness probes.

  • Liveness: Restarts the container if it crashes.
  • Readiness: Stops sending traffic to the container until it’s ready.

Security Context

Run containers as non-root users whenever possible to minimize the attack surface.

Conclusion

Following these best practices ensures your Kubernetes clusters remain stable, secure, and performant.
