How to manage Kubernetes secrets on AWS EKS

Kubernetes, a widely adopted platform for managing container workloads, faces challenges in handling sensitive information securely. Various solutions like HashiCorp Vault and AWS Secret Manager exist to address these issues, but using Mozilla's SOPS on Kubernetes, particularly within Amazon's EKS, offers a streamlined approach to safeguarding secrets. SOPS, an encrypted file editor, supports multiple formats and encryption methods, simplifying CI/CD pipelines without scalability issues. The guide outlines a method to use SOPS for managing secrets through AWS KMS keys, enabling specific permissions for different environments and users. It details deploying a WordPress application using AWS RDS MySQL for backend storage, emphasizing the importance of database maintenance and security. By leveraging tools such as Helm and Kubernetes External Secrets operator, SOPS allows secure management of sensitive data, preventing exposure while stored in version control systems like Git. These practices enhance security by encrypting secrets, limiting access through RBAC, and regularly rotating them, ensuring a robust and automated secret management system within Kubernetes environments.
