Use Cases

I'm a Terraform Cloud customer and I run hosted agents on linux/amd64 while me my coworkers and are working on darwin/arm64.

To make the provider cache work in tfc-agent, the hashes of the agent's platform providers must be present in the workspaces lock files, otherwise the agent will download all the providers at each run.

As we are working on MacOS, our terraform init or terraform init -upgrade commands ran in our workspace only vendor the hash for darwin/arm64. We also need to run terraform providers lock -platform=darwin_arm64 -platform=linux_amd64 to vendor hashes for multiple platforms.

I wonder if we could have a configuration in the workspace that automatically forces terraform init to lock providers for a given set of platforms so that we don't have to run the provider lock command. This would ensure that we don't forget to vendor tfc-agent's platform.

Proposal

terraform {
  required_providers {
    aws = {
      source    = "hashicorp/aws"
      version   = "~> 5.70"
      platforms = ["linux_amd64", "darwin_arm64"]
    }
  }
}
