Kubernetes Production Deployment (Recommended)

# Deploy using a standard Deployment and Service
kubectl create deployment orangehrm --image=orangehrm/orangehrm:latest
kubectl expose deployment orangehrm --port=80

• High Availability: Scale your web pods to ensure that project data is always accessible.
• Stateful Management: Use PersistentVolumeClaims to manage your HR data and uploaded employee documents.
• Secure Persistence: Use Kubernetes Secrets to manage your MySQL credentials and platform-level configurations.

Scaling & Performance

• Database Performance: For large organizations, optimize your MySQL instance and use read-replicas for heavy HR reporting.
• Document Offloading: Use shared persistent volumes or cloud object storage (S3) for all employee-uploaded documents.
• Load Balancing: Use a load balancer to distribute traffic across multiple OrangeHRM pods in the cluster.
• PHP Tuning: Correctly tune your PHP-FPM pool settings to handle high numbers of concurrent employee self-service users.

Backup & Safety

• Database Snapshots: Automate daily MySQL backups and store them offsite securely.
• Volume Backups: Regularly backup the persistent volumes containing employee documents and profile data.
• Security Updates: Monitor OrangeHRM's GitHub for updates and security patches.
• HTTPS Everywhere: Always run OrangeHRM behind a secure reverse proxy with SSL/TLS enabled to protect sensitive employee PII.
• Audit Logging: Enable and regularly monitor HR activity logs to ensure data access compliance.
