Pulumi YAML 1.0 has achieved General Availability, offering a stable, simple, declarative interface for Pulumi's Universal Infrastructure as Code platform, which is ideal for smaller-scale projects and serves as an entry point into Pulumi's ecosystem. This release includes key features such as full support for the pulumi convert feature, allowing seamless transition of YAML programs into other Pulumi-supported languages like Python, Java, Go, TypeScript, and C#, thus aiding in scaling up infrastructure complexity. Additionally, it provides improved IDE support with extensions for VS Code and Emacs, enhanced type checking and diagnostics, and a new str package for string manipulation. Pulumi YAML also enables the Pulumi Kubernetes Operator to define resources directly within Kubernetes YAML, offering a streamlined approach to manage cloud resources. This launch aims to cater to cloud teams familiar with markup languages by providing an on-ramp to more complex infrastructure management while retaining the ability to evolve with organizational needs.
