(sdkgen)=
SDKs
Provider SDKs ("software development kits") are generated from a
Pulumi Schema definition. Often referred to as "SDKgen", this process
is used by the myriad providers supported by Pulumi to expose their resources,
components, and functions in an idiomatic way for a given language. SDKgen is
generally exposed through the
method of a language host, which in turn is exposed by the
CLI's pulumi package gen-sdk
command. At a code level, SDKgen starts with the relevant GeneratePackage Go
function in gen.go -- see gh-file:pulumi#pkg/codegen/nodejs/gen.go for
NodeJS, gh-file:pulumi#pkg/codegen/python/gen.go for Python, and so on.
:::{note}
The pulumi package gen-sdk command is not really intended to be used by
external users or customers, and instead offers a convenient interface for
generating provider SDKs as part of e.g. the various provider CI jobs used
to automate provider build and release processes.
