Behebungsmethode: Anleitung oder Infrastruktur-Patch

Update workloads to consume secrets as mounted files instead of environment variables. Replace env[].valueFrom.secretKeyRef and envFrom[].secretRef usage with Kubernetes Secret volumes or the AWS Secrets and Configuration Provider with the Secrets Store CSI Driver, then update the application to read the secret from the mounted file path. This reduces the chance of secret values appearing in logs and aligns with the AWS-recommended file-based delivery pattern for EKS workloads. Replace secret environment variables with mounted secret files and update the application to read from the mounted path.
