The Pulumi Kubernetes Operator 2.0 introduces significant improvements in scalability and security for managing and deploying cloud infrastructure within Kubernetes environments. This updated version features a new architecture that assigns a dedicated "workspace" pod to each Pulumi stack, enhancing isolation and resource management. The Operator allows cloud deployments to be triggered based on changes in the Kubernetes Custom Resource, with support for various Pulumi languages and a wide range of cloud providers. Key enhancements include the ability to customize stack environments, use custom Docker images, and manage compute and storage resources. The 2.0 release addresses previous limitations by prohibiting cross-namespace references and requiring cluster-wide installation, ensuring that each stack's operations are isolated and secure. Security measures include using Kubernetes RBAC and minimal permissions for workspace pods. The system also supports efficient scaling by allowing resource customization and offers tools for inspecting and interacting with stack operations. With improved stability and new customization options, the Operator is designed to streamline the deployment of complex Kubernetes and cloud infrastructure setups.
