Hi all, has anyone implemented unit tests against a stack with required config values? How are you setting/mocking config values for the tests?

I'm trying to create a resource that depends on an

Output<ImmutableArray<T>>

, if I try to use Linq it doesn't create the resources. I have a workaround where I don't use Linq, but is there a better way to write this? I put my use case here https://gist.github.com/fracek/a94ff73d42b8f1aa180abe885982f7a4

General guidance is to avoid defining resources inside

Apply

calls. I think they should still be created but you may not see them in preview. A solution with a outside

Apply

would be preferred.

I see, so the best way is to define a list/array outside the

Apply

and Add the resources inside the

Apply

Code inside Apply won't run until the Output is resolved which may not happen during preview. So, whatever you do inside Apply may not be visible. If you can, do not new-up resources there.

Is there a way to explicitly mark an output as secret? I'm generating a connection string with

Output.Format

with a couple of sensitive values. In the old async stack system I used

Output.CreateSecret()

successfully, but I discovered in the new stack model that it wraps the output I give it, resulting in a signature of

Output<Output<string>>

, so I'm guessing it was never supposed to work that way.

I did try specifying

AdditionalSecretOutputs

on the resource property I wanted hidden, but that didn't do anything and I still got a plaintext string as the output.

It might be a stupid question, but how do you pass GetClientConfig in your stack ? I used to have everything in Program.cs before Pulumi 2.0. Now I have seen that in all the samples the infrastructure is defined in the constructors of classes that inherit from Stack. However I can't call InvokeAsync from GetClientConfig in constructors and if I call it in my Main method of Program.cs I don't know how to pass it to the stack constructor. Any idea how to do that ? It seems pretty basic but I can't find how to handle this.

Hi! Is there any guidance on how to overcome the chicken-and-egg-problem that you need a storage account (pulumi state) and an Azure Key Vault (secrets provider) to use Pulumi? Right now I use the Azure CLI in order to create those resources, but it would be nice if I could use Pulumi instead. 🤔

Hi. I have creates an Azure App Service using C# and specified the following (abbreviated) args

Copy code

var webApp = new AppService(name, new AppServiceArgs
{
    ClientAffinityEnabled = false,
    HttpsOnly = true,
}

I then wanted to create a deployment slot with the same setting. I was hoping to be able to pass the webApp in and read the settings in its AppServiceArgs and use them to apply to the SlotArgs (to ensure that they ended up identical) e.g.

Copy code

var webAppSlot = new Slot(name, new SlotArgs
{
    ClientAffinityEnabled = webApp.ClientAffinityEnabled,
    HttpsOnly = webApp.HttpsOnly,
}

This seems to work for the ClientAffinityEnabled setting but for the HttpsOnly setting I get an error... Cannot implicitly convert type 'Pulumi.Output<bool?>' to 'Pulumi.Input<bool>' Why are ClientAffinityEnabled and HttpsOnly behaving differently and is there a way to be able to read the HttpsOnly setting from the webApp and apply it to the slot App? Thanks Alan

I'm hoping someone with more knowledge on reflection can help me here... I'm trying use reflection in order to loop through all of the properties in a Pulumi.Azure.AppService.Inputs.AppServiceArgs object and copy them to a Pulumi.Azure.AppService.Inputs.SlotArgs object. I can manage the first level of boolean and string values like this (source is the AppServiceArgs object and target is the SlotArgs object)

Copy code

private static void CopyArgs(Object source, Object target)
{
    foreach (var sourceProp in source.GetType().GetProperties())
    {
        var targetProp = target.GetType().GetProperty(sourceProp.Name);

        switch (sourceProp.PropertyType.ToString())
        {
            case "Pulumi.Input`1[System.Boolean]": 
            case "Pulumi.Input`1[System.String]": 
                if (targetProp != null) targetProp.SetValue(child, sourceProp.GetValue(parent), null);
                break;
            default:
                break;
        }
    }
}

The problem comes when handling more complex types such as the SiteConfig which is of Type Pulumi.Azure.AppService.Inputs.AppServiceSiteConfigArgs in the parent object That is wrapped as a Pulumi.Input which means I need to call Apply to get at the contents I can manage that adding another case like this that determines the Types of the new, next level objects (e,g, the AppServiceSiteConfigArgs and SlotSiteConfigArgs in the case of SiteConfig) and then recursively calls the CopyArgs method with them as arguments...

Copy code

case "Pulumi.Input`1[Pulumi.Azure.AppService.Inputs.AppServiceSiteConfigArgs]":
                var newSource = (Input<AppServiceSiteConfigArgs>)sourceProp.GetValue(source)!;
                if (newSource != null)
                {
                    newSource.Apply(x => 
                    {
                        var newTargetProp = target.GetType().GetProperty(sourceProp.Name);
                        if (newTargetProp != null) 
                        {
                            var newTarget = (Input<SlotSiteConfigArgs>)newTargetProp.GetValue(target)!;
                            if (newTarget != null)
                            {
                                newTarget.Apply(y => 
                                {
                                    CopyArgs(x, y);
                                    return y;
                                });
                            }
                        }
                        return x;
                    });
                }
                break;

The problem with the above is that I have hard coded in casts for (Input<AppServiceSiteConfigArgs>) and (Input<SlotSiteConfigArgs>) which means I would need a new case for each potential type. What I'd really like to do is to be able to determine the types by reflection (so I can create newSource and newTarget in the above without the fixed casts) and call the appropriate Apply methods, presumably using an Invoke command. Unfortunately I haven't been able to work out how to do that and successfully. It seems quite complicated with the mix of generics and extension methods :( If anyone has any tips they would be greatly appreciated! Thanks Alan

Is it possible to build the pulumi project first and then just run the pre-compiled version or do I have to run

pulumi up

with the raw source available?

@tall-librarian-49374, what is the best way to create a

InputUnion.op_Implicit(80)

, and that isn't pretty 🙂

If i use

Copy code

var resourceGroup = ResourceGroup.Get("resourceGBla", "/subscriptions/4711/resourceGroups/resourceGBla")

and use it for a storage account, ResourceGroupName = resourceGroup.Name or ResourceGroupName = resourceGroup.Name.ToString() , it doesn't work. If i read in an existing resource, it is then possible to import the resource inside the stack ?

  ApplicationId = application.ApplicationId,

Is the best approach today to writing integration / acceptance tests in .NET is to shell out to pulumi.exe?

We are moving to using istioctl to install onto our Kubernetes clusters but this requires running that cli tool to generate the manifests so they can be created using pulumi. 1. pulumi runs istioctl manifest genetate 2. pulumi creates/updates resources. Right now the .net provider cannot run cli commands since dynamic providers are not yet supported. Is there an update when that will be supported or will we have to manually generate them for now?

How can I run async code once that is not supported by Pulumi? I would like to use Azure Key Vault (AKV) client to import a key from another AKV (based on a given certificate).

await akvClient.ImportKeyAsync("***.<http://vault.azure.net|vault.azure.net>", "MyKey", existingJsonWebkey);

I'm looking to create an EC2 instance per availability zone. I thought there used to be a C# demo that did this, but cannot find it. I check the examples project on github, but it is not there. Can anyone point me in the right direction for the code to loop through each availability zone in a given region?

var hostnames = new List<Input<string>>();
var ips = new List<Input<string>>();
foreach (var az in azs.Names)
{
