Version 3.0 of the Pulumi EKS Provider simplifies the process of managing role-based access control (RBAC) on Kubernetes, which is traditionally a complex and often mishandled task. By replacing the need for YAML configurations with TypeScript or JavaScript, Pulumi allows users to program Kubernetes objects directly using cloud SDKs, enhancing development speed and ease of updates. Pulumi's approach enables automated workflow for RBAC at scale, integrating easily with CI/CD tools like GitHub, GitLab, and others. The traditional sequential method of creating IAM roles and EKS clusters is contrasted with Pulumi's streamlined process, which involves updating a TypeScript file and running a single command to deploy all components simultaneously. This approach reduces complexity, particularly in environments with multiple users, namespaces, and clusters, by allowing all configurations and updates to be managed through code, thus improving security and maintainability. Pulumi also simplifies the process of mapping IAM roles to Kubernetes usernames during cluster creation, eliminating the need for additional configmap updates and ensuring that permissions are applied correctly and efficiently.
