Add model serving to stackit terraform provider

[rubenhoenle]

Could you add some examples for your new resource and datasource please?

Added the examples

[h3adex]

Please also runmake generate-docsand push the model_serving docs to this PR :-)

[PatrickKoss]

will come back to this pr once the stackit-go-sdk is released because I need the wait handler

@h3adex @rubenhoenle can you check again? Is this the right way to implement the default region if not in the provider specified?

[h3adex]

provider "stackit" {
  default_region           = var.stackit_region
  service_account_key_path = var.stackit_service_account_key_path
  enable_beta_resources    = true
}

resource "time_rotating" "rotate" {
  rotation_minutes = 1
}

resource "stackit_modelserving_token" "example" {
  project_id = var.stackit_project_id
  region     = "eu01"
  name       = "Example token"

  rotate_when_changed = {
    rotation = time_rotating.rotate.id
  }
}

Creating the datasource still has some issues:
when using the following terraform file:

resource "time_rotating" "rotate" {
  rotation_minutes = 60
}

resource "stackit_modelserving_token" "example" {
  project_id = var.project_id
  region     = "eu01"
  name       = "Example token"

  rotate_when_changed = {
    rotation = time_rotating.rotate.id
  }
}

data "stackit_modelserving_token" "exampleds" {
  project_id = var.project_id
  token_id   = stackit_modelserving_token.example.token_id
}

output "testoutput" {
  value = [
    "token id: ${data.stackit_modelserving_token.exampleds.token_id}",
  ]
}

the following error occurs

│ Error: Value Conversion Error
│ 
│   with data.stackit_modelserving_token.exampleds,
│ An unexpected error was encountered trying to convert tftypes.Value into token.Model. This
│ is always an error in the provider. Please report the following to the provider developer:
│ 
│ mismatch between struct and object: Struct defines fields not found in object: ttl_duration
│ and rotate_when_changed.
╵

The datasource has a different structure as the resource, so we probably need a dedicated model for the datasource

I also got a region error on the data-source.

fixed it

should be fixed

Ok, looks good now. Could you please provide a sample terraform file and some testing instructions, so we can do some acceptance testsing for this change. If it works, we can merge it asap. For future PR please try to avoid reformatting of existing code when not necessary to keep the diffs as small as possible

where do I need to add these instructions? I see there is some kind of acceptance test in each service.

[bahkauv70]

The testing instructions are commonly added to the JIRA issues (for this one it would be STACKITTPR-147. Note that due to permission issues the TPR project is most suitable. In this case however the terraform config is sufficient.

[bahkauv70]

Looks good now, all tests from my side worked
