### Description As part of fixing https://github.com/pulumi/pulumi-converter-terraform/issues/186 we need to be able to express resources and packages in PCL that are coming from parameterized providers. Today in PCL we will extract the package name from the token of a resource definition and load that package based on the name (using `LoadReference`) . For parameterized packages, this will not work because the schema of the parameterized resource is only available after we figure out which base provider is being parameterized and what the parameters are. In this PR we fix this problem by implementing top-level `package` blocks that are full package descriptors that contain sufficient information to load both classic resource plugins and parameterized packages. The block will looks like: ```tf package <name> { baseProviderName = <name> baseProviderVersion = <version> baseProviderDownloadUrl = <url> parameterization { name = <name> version = <version> value = <base64-encoded-value> } } ``` Example of a package descriptors for a `terraform-provider` provider parameterized with `hashicorp/random`: ```tf package "random" { baseProviderName = "terraform-provider" baseProviderVersion = "0.0.27" parameterization { name = "random" version = "3.6.2" value = "eyJyZW1vdGUiOnsidXJsIjoicmVnaXN0cnkub3BlbnRvZnUub3JnL2hhc2hpY29ycC9yYW5kb20iLCJ2ZXJzaW9uIjoiMy42LjIifX0=" } } resource "randomPet" "random:index/pet:Pet" { length = 10 } ``` Now when we extract the package name from `random:index/pet:Pet => random` we check if there is a package descriptor for it and use that descriptor to load the package, parameterizing the base provider when necessary. Otherwise if the package name doesn't have a descriptor, we fallback to old package loader that expects plugin `pulumi-resource-<packageName>` to be available in the plugin cache or PATH. These blocks are not mapped to specific `Program` nodes, they are read from the AST after the PCL files have been parsed. This information can be easily made available to `pcl.Program` if needed since it has access to the source binder. ### Conformance Tests With the ability to parameterize packages from a PCL program, we can support conformance testing parameterized providers! I've implemented a new test `l2-parameterized-resource` which implements a parameterized provider that has a schema and runtime behaviour dictated by the values it was parameterized with. ### Test this locally You can test this locally with different parameterized providers, you will need their parameter values which you can retrieve from the schema: ``` pulumi package get-schema terraform-provider hashicorp/random > random-schema.json ``` In `random-schema.json` you will find values you need in `$.parameterization` ### Converted Code The program above can be successfully converted to TypeScript for example and generates the following: ```ts import * as pulumi from "@pulumi/pulumi"; import * as random from "@pulumi/random"; const randomPet = new random.Pet("randomPet", {length: 10}); ``` This program loaded the parameterized schema and used it to generate the resource definition correctly. However the following still need to be addressed: - The `pulumi convert` doesn't generate the local SDKs are part of the conversion. Doing this might make https://github.com/pulumi/pulumi-converter-terraform/issues/186 a lot easier than expected. cc @brandonpollack23 - Program generators do not understand parameterized packages so they reference them like any of our provider sdk `"@pulumi/random": "3.6.2"` (this is wrong because there is not such sdk on npm). They should expect the SDK to be available locally and reference it via a relative path - ~We need a good way to (conformance) test these~ DONE ✅ |
