The Pulumi Kubernetes Operator 1.0 release introduces significant enhancements and improvements in scalability, performance, and quality, building on its initial launch as a cloud-native tool for managing and deploying cloud infrastructure within Kubernetes environments. This operator defines a Kubernetes Custom Resource called pulumi.com/v1/Stack, which allows users to deploy and manage cloud resources in various supported clouds using languages like TypeScript, Python, Go, and .NET. The 1.0 version supports GitOps workflows with branch tracking, private Git repositories, and integrates with the Pulumi Automation API, which simplifies operator implementation and enhances compatibility with numerous projects. Furthermore, the operator offers support for diverse state and secrets management backends, including S3 and Azure Blob for state storage and KMS and Vault for secrets management. To ensure minimal disruption during upgrades, features such as Leader Election and Graceful Shutdown have been added, alongside Prometheus-compatible metrics for better operational insights. Enhanced documentation and guides are also available to facilitate easier adoption and deployment of the Pulumi Kubernetes Operator.
