Description

Currently, there doesn't seem to be a way to reference a secret stored in Google's Secret manager when creating a function with the TF resource (available in the UI)

New or Affected Resource(s)

• google_cloudfunctions_function

Potential Terraform Configuration

resource "google_cloudfunctions_function" "func" {
  project   = var.project_id
  name        = "my-func"
  runtime     = "python38"

  ...

  secrets {
      secret_id = "my-secret-1"
      reference_method = "VOLUME"
      mount_path = "/my-secret-1"
      paths = [
        {
          path = "/v1"
          version = "1"
        }
      ]
  }

  secrets {
      secret_id = "my-secret-2"
      reference_method = "ENVIRONMENT_VARIABLE"
      variables = [
        {
          name = "MY_SECRET_2"
          version = "latest"
        }
      ]
  }
}

Hi

The provider doesn't implement features in Private Preview. Also, the provider doesn't support the new version of Functions yet as it is in Private Preview.

Thank you

As a side note: while the support for this feature is yet to be added to the provider, assuming the other dependencies are met, an interim option to automate this secret manager integration is by wrapping the gcloud command in a gcloud module or as a local-exec step.

When we can see this feature in the google or google-beta provider?

[upodroid]

Hmm

The feature exists in v1 of the API but it isn't undocumented here https://cloud.google.com/functions/docs/reference/rest/v1/projects.locations.functions

The command gcloud beta functions deploy NAME(this function has to exist) --runtime dev --set-secrets '/etc/foo=dev:latest' --log-http

yields a payload that looks like this:

Lets wait a bit for the API docs to be updated.

the feature has arrived in beta

[--clear-secrets
          | --set-secrets=[SECRET_ENV_VAR=SECRET_VALUE_REF,
          /secret_path=SECRET_VALUE_REF,
          /mount_path:/secret_file_path=SECRET_VALUE_REF,...]
          | --remove-secrets=[SECRET_ENV_VAR,
          /secret_path,/mount_path:/secret_file_path,...]
          --update-secrets=[SECRET_ENV_VAR=SECRET_VALUE_REF,
          /secret_path=SECRET_VALUE_REF,
          /mount_path:/secret_file_path=SECRET_VALUE_REF,...]]

Any updates on this?

This is blocking us from adopting Terraform for our cloud functions. Eagerly awaiting support for function secrets in the provider.

[kakarott1511]

Really need this feature in terraform as we are blocked and can't go in prod. We don't want to do workaround to use this feature.

[binamov]

This should've rolled out already, can we close this?
