Pulumi Packages are a central technology within Pulumi's cloud infrastructure provisioning framework that allows resources to be defined in one language and utilized across all Pulumi-supported languages. Initially, these packages were limited to low-level Pulumi Resources, but with Pulumi 3.0, they can now include high-level Pulumi Components, enabling multi-language support and broader usability. This advancement allows developers to create components in their preferred language, making them accessible to others regardless of the programming language they use. Users can easily integrate Pulumi Packages into their projects by finding and installing them via various registries such as npm, PyPI, or NuGet. Pulumi Packages can be native providers, bridged from existing ecosystems like Terraform, or custom components, expanding the variety of resources available to developers. The community is encouraged to author and share Pulumi Packages to enhance the platform's capabilities further, with ongoing improvements to simplify their creation and distribution.
