Kubernetes in Production
There are big differences between using Kubernetes in development and production environments.
Security
RBAC
Role-Based Access Control must be active. Minimum privilege principle should be applied for each service.
Network Policies
Network policies restricting traffic between pods should be defined.
Secrets Management
Secrets should be managed with tools like HashiCorp Vault or AWS Secrets Manager.
High Availability
Multi-Node Cluster
Use at least 3 master nodes. Quorum should be ensured for etcd.
Pod Disruption Budgets
Ensure minimum replica count during maintenance.
Monitoring
Conclusion
Kubernetes is a powerful platform but requires careful planning in production.
