Description

This adds support to the Firebase Functions CLI to deploy onGraphRequest functions. The deployed function will by default be IAM restricted to the Firebase Data Connect P4SA, with any explicitly specified invokers also granted access.

In addition, if schemaFilePath is specified in the onGraphRequest options, the CLI will pull in the schema GQL source files at schemaFilePath and bundle them with the functions deploy payload.

Summary of Changes

Hello @rosalyntan, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the Firebase Functions CLI to properly support the deployment of onGraphRequest functions by integrating the necessary IAM permissions for the Firebase Data Connect service. It introduces mechanisms to identify the correct Data Connect service account for different environments and ensures that this service account is granted the cloudrun.invoker role, which is essential for Data Connect to interact with Cloud Run functions.

Highlights

  • Data Connect IAM Bindings: Introduced new logic to determine and apply necessary IAM bindings for the Firebase Data Connect service agent, specifically granting the cloudrun.invoker role to enable interaction with Cloud Run functions.
  • Environment-Specific Service Accounts: Implemented dynamic determination of the Data Connect service account based on the deployment environment (autopush, staging, or production) to ensure correct permissions are applied.
  • Deployment Flow Integration: Updated the dataconnectService configuration to utilize the new obtainDataConnectBindings function, integrating these essential IAM permissions directly into the functions deployment process.

this would end up clearing up the invoker setting to "private", including getting rid of access for FDC P4SA 🤔 wondering if that's what we want

I think this is addressed with my changes in fabricator.ts -- what is a test case that would trigger this? I've verified that removing the invoker from the options when redeploying does not remove access for the FDC P4SA.

i don't think it's useful to print trigger url for FDC urls, esp. since it's not meant to be a public function.

We need the URL printed so developers can copy-paste it into their dataconnect.yaml files. However, I realized that this logic wasn't actually working, so updated with a fix. In addition, it seems like only the non-deterministic run.app URL gets returned from the backend, so I manually construct the deterministic URL here (it's a little hacky).
