Implementing assurance pipeline for Amazon EKS Platform

This article details how to build a comprehensive assurance pipeline for Amazon EKS clusters using six validation frameworks integrated into a GitLab CI/CD pipeline.

• Infrastructure validation using Terraform test framework catches configuration errors early
• Behavioral testing with Pytest BDD verifies cluster operations and component interactions
• Helm testing validates application deployments and service accessibility
• Policy compliance testing with Chainsaw ensures security policies are enforced
• Performance assessment using Locust identifies bottlenecks under load conditions
• Resilience testing with AWS Resilience Hub and FIS validates failure recovery
• Pipeline includes stages for validation, deployment, testing, and resilience assessment
• Automated validation reduces manual testing, catches issues early, and improves reliability
• Framework provides confidence in production-ready Kubernetes environments

The assurance pipeline provides systematic validation across infrastructure, applications, policies, and resilience to ensure EKS clusters meet organizational standards and production requirements.
