Expected Behavior

When creating a PubSub Topic Lite there should be two options for location: Regional or Zonal.

Actual Behavior

For deploying Zonal Topic, it is straight forward since you only need to provide a region and a zone. (No issue)
For deploying Regional Location, there is no clear way to choose this option. If the zone is removed from the arguments it throws and error that a zone must be provided. So it seems, regional location for PubSub Lite Topic is not an option at the moment.

@flpablo it is fine with me with either zone or region provided. Can you try one like below?

resource "google_pubsub_lite_topic" "example" {
  name = "example-topic"
  project = data.google_project.project.number

  partition_config {
    count = 1
    capacity {
      publish_mib_per_sec = 4
      subscribe_mib_per_sec = 8
    }
  }

  retention_config {
    per_partition_bytes = 32212254720
  }

  reservation_config {
    throughput_reservation = google_pubsub_lite_reservation.example.name
  }

  region = "us-west1"
  //zone = "us-west1-a"
}

@edwardmedia I tried as mentioned but still I got the error of not determine the zone:

`% terraform apply google_pubsub_lite_reservation.example-reservation: Refreshing state... Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:

Terraform will perform the following actions:

Let me know if you need more information. Thank you for your help.

edwardmedia commented 2 years ago

@flpablo I see what is going on. Do you have below environment variables available? Please set them if you don't have. Those become required if you don't have them setup.

https://registry.terraform.io/providers/hashicorp/google/latest/docs/guides/provider_reference#zone

flpablo commented 2 years ago

@edwardmedia Yes, I've tried setting the environment variables, but the problem is that it creates (by default) the topic to be "Zonal lite topic". I can't figure out how to "overcome" this behavior and create a "Regional lite topic". In the example code you provided a few days ago, did it created a "Regional" topic?

jessee-kung commented 2 years ago

Same question here. It seems that there's no option to configure the Pub/Sub Lite topic as Regional or Zonal?

Providing region and left the zone argument empty leads the same 400 error:

resource "google_pubsub_lite_topic" "topic" {
  name    = "my_topic"
  project = data.google_project.project.number
  region  = "us-west1"
  ...
}

Result:

Error: Cannot determine zone: set in this resource, or set provider-level zone.
│ 
│   with module.infra.module.pubsublite["my_topic"].google_pubsub_lite_topic.topic,
│   on ../../modules/infra/pubsublite/deployment.tf line 10, in resource "google_pubsub_lite_topic" "topic":
│   10: resource "google_pubsub_lite_topic" "topic" {
│

Provding both region and zone argument as the value of region argument (e.g., all filled in us-west1, which looks weird), it creates regional topic:

resource "google_pubsub_lite_topic" "topic" {
  name    = "my_topic"
  project = data.google_project.project.number
  region  = "us-west1"
  zone = "us-west1"
  ...
}

Result:

Apply complete! Resources: 1 added, 0 changed, 0 destroyed.

It should be unexpected behavior.

edwardmedia commented 2 years ago

I see where the problem is. To fix it, 1) Need to update all urls like below to dynamically assign {{location}} with either region or zone whichever is available. If region is picked, the regional resource is created. When zone is used, the resource becomes zonal.

{{PubsubLiteBasePath}}projects/{{project}}/locations/{{location}}/topics?topicId={{name}

2) ExactlyOneOf needs to be added to both region and zone as only one of them is used. But this is breaking-change.

edwardmedia commented 2 years ago

It might be better to add the new field location, and remove both region and zone. It is a feature request and add the label with enhancement accordingly
