Description

In September 2020 GCP introduced Workload identity federation that allows external workloads to use AWS, Azure or OIDC credentials to get a Google Cloud accessToken without using a service account key. This is a very important feature for multi-cloud workloads and it would be great if we can use Terraform to provision 'WorkloadIdentityPools' and 'WorkloadIdentityPoolProviders'

New or Affected Resource(s)

I would expect new resources/data sources for:

• google_project_workload_identity_pool
• google_project_workload_identity_pool_provider although the arguments are different for the two types of providers, so perhaps it is easier to split this into two resources: google_project_workload_identity_pool_provider_aws and google_project_workload_identity_pool_provider_oidc

A pools and providers are created/changed async, so they return an Operation that we need to poll, which is similar to many other google cloud resources.

@rileykarson I think this should be left open until WorkloadIdentityPoolProviders is also created since both are in the criteria and description of the issue?

Yep- whoops! Over-aggressive Fixes statement 🙂

Thanks!

Now that the first data source is merged, I’ll create the second data source which should complete this issue.
