Running Kubernetes in production requires careful planning and adherence to best practices. Here are the essential guidelines every team should follow.
Resource Management
Proper resource management is crucial for stable Kubernetes clusters. Always set resource requests and limits for your pods to prevent resource contention and ensure predictable performance.
Security Considerations
- Use non-root containers whenever possible
- Implement network policies to control traffic
- Regularly update base images and dependencies
- Use RBAC to control access to cluster resources
Monitoring and Observability
Implement comprehensive monitoring from day one. Use tools like Prometheus and Grafana to monitor cluster health, application metrics, and resource usage.
Backup and Disaster Recovery
Regular backups of etcd and persistent volumes are essential. Test your disaster recovery procedures regularly to ensure they work when needed.
