Hi I’m trying to conver pulumi output object to string that can be assign to variable and used as a parameter in curl request. Im following documentation https://www.pulumi.com/docs/intro/concepts/programming-model/#outputs

repo_id = gitlab_repo.id.apply(lambda repo_id: repo_id)

when I try to print this variable I all the time getting

<pulumi.output.Output object at 0x10acc5a00>

how I can get raw string that can be used in curl request

I want to add gitlab environment

And I need repo id for a request

Lambda converts from Output to Output. If your need to do something with the actual value you need to do that inside the apply

hmm ?

steep-alligator-79173

08/28/2020, 7:45 PM

gilab_repo.id.apply(function_that_receives_the_id)

i create resource :

gitlab_repo = pulumi_gitlab.Project(
        f"{repo}",
        name=repo,
        namespace_id=qtx_arc_group.id
    )

steep-alligator-79173

08/28/2020, 7:45 PM

and now I need repo id in raw string

steep-alligator-79173

08/28/2020, 7:45 PM

not as a output

green-school-95910

08/28/2020, 7:46 PM

Isolated the logic that need the id and pass it to the apply, as I showed above

steep-alligator-79173

08/28/2020, 7:49 PM

repo_id = gitlab_repo.id.apply(lambda repo_id: f"dupa+{repo_id}")
    pulumi.export("DUPA", repo_id)

steep-alligator-79173

08/28/2020, 7:49 PM

Outputs:
  + DUPA: "dupa+20804159"

steep-alligator-79173

08/28/2020, 7:49 PM

results are as expected

steep-alligator-79173

08/28/2020, 7:50 PM

but I don’t understand part with

can you explain this in more details. ?

steep-alligator-79173

08/28/2020, 7:51 PM

as i understand in side apply i should execute function that need this raw id

Yes, the code inside the apply is executed during the deployment, when that information (the id) is guaranteed to be available The code outside is executed before the deployment, it is the code that define the graph of resources. When that code is running, the id is not known, only the reference to its future value (the Output object) is available.

So any code that needs the actual value of a resource should go inside the apply. Normally you only need to transform it to something else

repo_id = gitlab_repo.id.apply(lambda repo_id: f"dupa+{repo_id}")

repo_id

here is an

Output

object representing a value that, during the deployment, will be available and equal to the result of the lambda function The

pulumi.export("DUPA", repo_id)

don't export anything. It adds to the plan that after the deployment the values that was made available on that Output should be exported.

You can just treat it as if it exported things for most cases, but if you need more control you also need to understand this difference

I get to the point:

repo_id = gitlab_repo.id.apply(lambda repo_id:
      print(f"<https://gitlab.com/api/v4/projects/{repo_id}/environments>")
      
)

steep-alligator-79173

08/28/2020, 8:20 PM

output looks ok

steep-alligator-79173

08/28/2020, 8:20 PM

now I will try to execute requests inside with paramteres

steep-alligator-79173

08/28/2020, 8:21 PM

repo_id = gitlab_repo.id.apply(lambda repo_id:
      print(f"<https://gitlab.com/api/v4/projects/{repo_id}/environments>")
      requests.get("<https://gitlab.com>")  
    )
