Hi, Can I use SQL queries within a pulumi deployment project to check for the existence of a record, and create it if it doesn't exist?

I have a network stack that is creating a vpc and a bunch of public subnets:

[Output] public Output<string> VpcId { get; set; }
[Output] public Output<ImmutableArray<string>> PublicSubnetIds { get; set; }

and am trying to reference these from another stack. I can reference the stack and can get the VpcId back using:

var network = new StackReference(SeparateNetworkStackName);
var vpcId = network.GetOutput("VpcId").Apply(x => x.ToString());

However, I can't work out how to retrieve the array of public subnets. These would seems like a fairly common operation. Anyone know how to do it?

Appear to have got this working. Can't believe this is the right way to do it, so if someone knows the right way, please let me know. This is what I did:

Output<object> publicSubnetIds = network.GetOutput("PublicSubnetIds");
Output<ImmutableArray<object>> subnets = publicSubnetIds.Apply(x => (ImmutableArray<object>) x);
var secondPublicSubnetId = subnets.Apply(x => x[1].ToString());

You should be able to do something like:

stack.GetOuput("output").Apply(x => x as string[]);

Thanks Phillip. I tried this but I don't think it works if your Output is ImmutableArray<string>>. I guess, I could change the stack output to be Output<string[]>, but will leave as is for the moment.

Very cool. Not played with the automation api yet, but planning to and examples are handy. Pulumi is fantastic, but sometimes there is a lack of examples - perhaps due to the fact that is supports a number of languages.

TIL how to compile a project against a local .NET Pulumi SDK. Replace

<PackageReference Include="Pulumi" Version="3.9.1" />

with

<ProjectReference Include="..\..\..\..\pulumi\sdk\dotnet\Pulumi\Pulumi.csproj" />

everywhere and add

<AssemblyVersion>3.9.0.0</AssemblyVersion>

Pulumi.csproj

. Not as seamless as

replace

command I got used to in

go.mod

but it helped me a lot making iterative changes. Is that how folks do it or is there an easier way?

Hi, I'm new to Pulumi and I was wondering if someone could point me to an example of a real life implementation of a ComponentResource in dotNet. My apologies if this question has already been addressed and answered in the past.

As we don't have dynamic resource provides in .NET, is there a way to detect when a stack is being destroyed? My scenario is that we've implemented a

CustomResource

that adds some database entries. I'd like to remove those entries if the resource is being destroyed. I'm pretty sure that the answer, if there is one, is that something will need to be executed outside of the

CustomResource

derived class.

Hi, I'm using the azure native provider and I can't find a way to create an empty data disk and then attach it to a new vm. Any help is much appreciated. Thank you !

is it possible to have a component resource inherit from another component resource? We've got a component resource that we'd like to make some of the methods virtual and overwrite them in a child class, but it looks like it might not be possible, particuarly because we can't register the child class with the component resource class

Ok I have to be doing something dumb. I have read inputs and outputs a hundred times and I still can't figure out how to get an output value to resolve as a string when I need it to build a say a script value for another resource. I have tried

var x = resource.prop.Apply(x => x)

bulky-policeman-29913

09/05/2021, 7:10 PM

etc and still it just shows Pulumi.Output as the value (ie: tostring in c# of an object)

09/05/2021, 7:40 PM

nevermind it just registered you cant pass a string to an input it has to be an input or an output to resolve dependencies...light bulb moment 💡

Using the pulumi/pulumi-dotnet docker image to integrate pulumi into a deployment pipeline. Although just found that it's still using .NET Core 3.1 (and not .NET 5). Any suggestion on my best course of action here? I could write my own docker image - I don't really see another way? Thanks 🙂

We provision a “hub and spoke” network topology with several projects and stacks that span subscriptions. When provisioning spokes we use two providers to provision peering from hub to spoke and spoke to hub. When a spoke stack is destroyed peerings are properly removed, all good. When the hub is updated all subnet peerings are dropped, not so good. Running Pulumi refresh and Pulumi up on each spoke stack restores the missing peerings but is there a better way? All spokes could be provisioned with a single stack but that feels wrong. Thoughts?

How to structure your .net files? What is the best practice for structuring the .cs files in a large stack within a project. In Terraform, you would typically group all of the resource related to the same "thing" into a .tf file For example for an Azure Function, the app service plan, storage and app service itself might all go into one .tf file. What is the equivalent for Pulumi to avoid having one giant .cs file for the stack (or is the answer that I should have a stack for each "thing" in my system and use Stack References to create inter-stack dependencies?). I have thought about using

partial class

but wanted to reach out to see if there are any conventions?

I keep fighting outputs... given an

Output<ImmutableArray<string>>

(of aws subnet ids fwiw), I need to create a bunch of aws resources for each subnet. Unless I'm missing something, there doesn't seem to be a nice way to enumerate the array outside of apply, since there's no way to get the array length, unless I use

OutputUtilities

Appsettings.json and Secrets.json in Pulumi. What are the best practices for using

appsettings.json

and

secrets.json

in C# Pulumi projects? My scenario is that I want to use a connection string for a resource on a completely different resource group. not controlled by pulumi as an application setting for my azure app service. I want to store the value of this connection string in

secrets.json

like I would for any typicaly .net application. The only docs I can find is this https://www.pulumi.com/blog/7-ways-to-deal-with-application-secrets-in-azure/#2-configuration-files but this simply says "_With some configuration not shown here, the properties are filled at startup_", but it is the stuff that is not shown that I would love to see.

Quick one. I have an args property of

Input<string>

and I need to assign it to an

object

type in my values object map, but implicit typing doesn't kick in so the assigned value is Input<T>. See below... the

args.DatadogApiKey

is `Input<string>`:

var datadogChart = new Chart("datadog-chart",
                new ChartArgs
                {
                    Chart = "datadog",
                    Version = args.DatadogChartVersion,
                    Namespace = "default",
                    Values = new Dictionary<string, object>
                    {
                        ["datadog"] = new Dictionary<string, object>
                        {
                            ["apiKey"] = args.DatadogApiKey,
                            ["site"] = "<http://datadoghq.eu|datadoghq.eu>"
                        },
                    }
                });

Hi, I've tried to import existing resources with import command. The case is that the code seems incorrect, as I get some errors, for example look below

var aks_mypool_12128392_vmss = new AzureNative.Compute.VirtualMachineScaleSet("aks-mypool-12128392-vmss", new AzureNative.Compute.VirtualMachineScaleSetArgs
{
    DoNotRunExtensionsOnOverprovisionedVMs = false,
    Identity = new AzureNative.Compute.Inputs.VirtualMachineScaleSetIdentityArgs
    {
        Type = "UserAssigned",

The Type property is of type Input<Pulumi.AzureNative.Compute.ResourceIdentityType>? and it seems there's no implicit conversion from string. Is it a bug ?

Is it possible to specify JsonSerializerOptions to use with the Pulumi.Config.Get/Require methods or would I need to specify it manually as an attribute for each property in my model?

Hi everyone, I'm having an issue that hopefully someone can help with 🙂 I am building my dotnet project and then setting

runtime:options:binary

in my Pulumi.yaml pointing to the built DLL. However, now when running

pulumi preview

, I get

Error: no resource plugin 'azure-native-v1.34.0' found in the workspace or on your $PATH

. Without the binary option, pulumi is working, and strangely my stack is using v1.33 of the azure-native plugin

Hello friends! I’m running into some difficulty deeply converting

inputShape(T)

style records to

Input<T>

with the facilities in the SDK, specifically Inputs.GetAmiIdsFilterInputArgs to Inputs.GetAmiIdsFilterArgs from the AWS provider. GetAmiIdsFilterInputArgs essentially is a record that’s deeply transformed by codegen to insert

Input<_>

layer everywhere to make it easier for the users to pass outputs in. In my work I need to “unnest” all these inputs back. I found a different way forward but it’s striking me as not exactly elegant and it will make the implementation diverge from what we have in some other language SDKs. So I’d like to solicit feedback here, perhaps I’m missing something obvious.

That's a lot to take in, so rather than try to understand it all I'll just ask some dumb questions... • is this a problem to be solved at compile time or run time? • if codegen is used to create one type, can't it be used to create the other?

enough-garden-22763

10/04/2021, 8:13 PM

Both compile-time and runtime solutions are acceptable here

Codegen doesn’t seem to be smart enough at the moment to be able to create a function that auto-converts between the two types. So I was hoping that runtime can.

The runtime is, it seems, capable of serializing both types to the same underlying structure.

I’d prefer a runtime solution as not to generate too much converter code.
