How would one get the latest of a SpotInstanceRequest? Are there any examples out there? I'm trying to do something like:

var spotOutput = Pulumi.Aws.Ec2.SpotInstanceRequest.Get(spotRequest.GetResourceName(), spotRequest.Id, null, new CustomResourceOptions
                {
                    DependsOn = spotRequest
                });

But it keeps giving me an error: of

aws:ec2:SpotInstanceRequest (dev-request-1):
    error: resource 'urn:pulumi:dev::aws-spot::aws:ec2/spotInstanceRequest:SpotInstanceRequest::dev-request-1' registered twice (create and read)
    error: resource 'urn:pulumi:dev::aws-spot::aws:ec2/spotInstanceRequest:SpotInstanceRequest::dev-request-1' registered twice (create and read)

I'm not aware of a specific spot instance example, but that error is a general error about re-using the same logical name for the same resource/lookup. Specifically, you can change the first argument in

.Get(spotRequest.GetResourceName(), ...

to a different value to avoid that error.

Thanks. The way the doc read, I was thinking it wanted the name of the existing resource to lookup. How do I get the value out of it now though, @gentle-diamond-70147? I've tried:

var spotOutput = Output.Create(Pulumi.Aws.Ec2.SpotInstanceRequest.Get($"{spotRequest.GetResourceName()}-{i}", spotRequest.Id, null, new CustomResourceOptions
                {
                    DependsOn = spotRequest
                }));

                
                Console.WriteLine($"{spotOutput.Apply(x => x.SpotInstanceId)}");

And

var spotOutput = Pulumi.Aws.Ec2.SpotInstanceRequest.Get($"{spotRequest.GetResourceName()}-{i}", spotRequest.Id, null, new CustomResourceOptions
                {
                    DependsOn = spotRequest
                });

                
                Console.WriteLine($"{spotOutput.SpotInstanceId.Apply(x => x)}");

Can you switch it up...

spotOutput.SpotInstanceId.Apply(x => Console.WriteLine(x));

? Apologies, C# isn't my go-to language, but that's how you would do it in one of the other languages.

That gives a syntax error, but let me see if there's a way to change it up.

Do you get the same `Pulumi.Output`1[System.String]` output? Or are you getting an error?

Syntax error:

Hmm, let me get someone more knowledgeable than me to chime in. 🙂

@best-receptionist-98400 this should give you a little more guidance about how to make a get request and then use it

Thanks! I will check it out soon!

Spotinst itself may not have a datasource i.e. GetSpotInstanceRequest, but the Get should work the same

Ok, I didn't think so. I don't have a repo yet, but it would be easy enough to spin one up if I don't figure it out tonight. Thanks, @broad-dog-22463! Have a good evening!

I haven’t tested it but this would be my approach: https://github.com/efleming18/pulumi-examples/pull/1

@tall-librarian-49374 This looks to be working! I was able to leverage the SDK in there to tag the instances. This is great to be able to just run the one command and have everything created and tagged appropriately even given some the AWS limitations. One thing I was wondering. Do I even need to do the "Wait" approach here if I use the

DependsOn

on the

SpotInstanceRequest.Get

? I've run this a few times this morning and it's always worked the first try. I'm assuming because I have the DependsOn as well as the

WaitForFulfillment

set on the initial spot request? Or am I just getting lucky that the value has always been ready the first time?

This depends on AWS behavior. The ID should always be there, but I thought you said that the AWS SDK operation may fail for a while.

The AWS SDK operation should only fail if the instance isn't there yet. But with how we currently have it set up, that would never be possible now since we check to make sure the

SpotInstanceId

is there before running the SDK operation.
