There are three production Kubernetes must-haves—skip any one and you’ll get a surprise post-deploy. This article summarizes the critical checklist based on K8s 1.31+.

Resource Limits

        
        
        
    
resources:
  requests:
    memory: "256Mi"
    cpu: "250m"
  limits:
    memory: "512Mi"
    cpu: "500m"

Health Checks

        
        
        
    
livenessProbe:
  httpGet:
    path: /healthz
    port: 8080
  initialDelaySeconds: 30
  periodSeconds: 10

readinessProbe:
  httpGet:
    path: /ready
    port: 8080
  initialDelaySeconds: 5
  periodSeconds: 5

Rolling Updates

        
strategy:
  type: RollingUpdate
  rollingUpdate:
    maxSurge: 25%
    maxUnavailable: 25%

Conclusion

Kubernetes production trio: resource limits + health checks + rolling updates.

Skip these three, don’t go to production.
