What's a reliable way to build a Pulumi Terraform "Plugin Framework" bridge provider? Toying with https://github.com/joneshf/terraform-provider-openwrt/tree/main/openwrt I tried manually, but the tf-bridge development seems in flux, and got lost. Got further along with the cookiecutter project, but now I'm running into this error - which makes no sense since I didn't publish anything yet. Why would it try to download it for the ts example project? I'm still very much "in dev mode", trying to sort things out.

Code here: https://github.com/deposition-cloud/pulumi-openwrt - in case anyone familiar with the bridging workflow wants to have a look; what am I missing? ...after the second run of 
make tfgen
I noticed the 
.dirty
suffix—what exactly is happening here?

Have you run 
make provider
to build the provider binary so it's on $PATH?
s
Not sure I follow, the Makefile does:
Copy code
provider:: tfgen install_plugins # build the provider binary
	(cd provider && go build -o $(WORKING_DIR)/bin/${PROVIDER} -ldflags "-X ${PROJECT}/${VERSION_PATH}=${VERSION}" ${PROJECT}/${PROVIDER_PATH}/cmd/${PROVIDER})
Had to inquire ChatGPT: The command performs the following actions: 1. Change Directory: It changes the current directory to 
provider
using 
cd provider
. 2. _Go Build: It then runs 
go build
to compile the Go code located in 
${PROJECT}/${PROVIDER_PATH}/cmd/${PROVIDER}
._ 3. _Output: The compiled binary is saved to 
$(WORKING_DIR)/bin/${PROVIDER}
._ 4. Linker Flags: It sets some linker flags to embed the version information into the binary. This make task doesn't seem to add anything to the PATH, so I symlinked 
./bin/pulumi-resource-openwrt
to 
~/go/bin/pulumi-resource-openwrt
and it was picked up ✅. Next error 🙂

I can only guess it's complaining about this line: https://github.com/deposition-cloud/pulumi-openwrt/blob/109b949f89b1cb83cbdc3be8244cdd3eb5d97900/provider/resources.go#L83 (?) Am I returning the right thing here: https://github.com/deposition-cloud/pulumi-openwrt/blob/109b949f89b1cb83cbdc3be8244cdd3eb5d97900/provider/resources.go#L187
Copy code
return pf.ProviderInfo{
		ProviderInfo: prov,
		NewProvider: func() pfprovider.Provider {
			return openwrt.New(version.Version, os.LookupEnv)
		},

Ah right some of our provider makefiles build directly to /go/bin, assumed this one was the same. Just symlinking works.

That pluginUrl looks fine. It might be you just need to update the deps in go.mod to the lastest version of github.com/pulumi/pulumi-terraform-bridge/v3 and github.com/pulumi/pulumi-terraform-bridge/pf

Only as a small sidenote. I always perform intial tests for a new Pulumi provider, e.g. which has been wrapped by using the TF bridge, with a YAML program. The advantage of Pulumi YAML is that the provider executable only needs to be present in the path. The complete (correct) setup, e.g. for Node via yarn link, can then be omitted for the time being.

@echoing-dinner-19531 hm, upgrading seems to break the contract https://github.com/pulumi/pulumi-terraform-bridge/blob/master/pf/tfbridge/main.go doesn't export a 
ProviderInfo
struct anymore, so the code I shared above breaks @big-architect-71258 - any plans to upgrade your cookiecutter?
b
@straight-cartoon-24485 Mind opening an issue in my repo? And I think the issue might stem from a breaking change in TF PF mentioned by @orange-policeman-59119 a couple of weeks ago. But I didn't have any time to look at it or even incorporate the required changes into the template yet.
@straight-cartoon-24485 I just published v0.0.12 of the Cookiecutter Template with fixes to the breaking change mentioned in the issue you opened. @billowy-army-68599
