patriksvensson/cupboard: A framework for provisioning local environments to a desired state, using the .NET SDK.

A framework for provisioning local environments to a desired state, using the .NET SDK.

Currently in preview. Use at own risk.

In Cupboard, you define catalogs, manifests, and resources.

• Resources:
  A resource describes the desired state for some part of a system.
  This might be a file, directory, package, etc.
• Manifests:
  A manifest contains one or many resources.
  Used to specify how to assemble parts that uses many resources.
• Catalogs:
  A catalog contains one or many manifests.
  Used as a logical grouping of machines and/or platforms.

Start by creating a new console application targeting .NET 8.0.
Add a reference to the Cupboard NuGet package.

> dotnet new console
> dotnet add package Cupboard

Let's start by creating a manifest that defines what should be run.

Note that resources don't do anything when they're declared.
They describe what WILL be done when executed.

public sealed class Chocolatey : Manifest
{
    public override void Execute(ManifestContext context)
    {
        // Download
        context.Resource<Download>("https://chocolatey.org/install.ps1")
            .ToFile("~/install-chocolatey.ps1");

        // Set execution policy
        context.Resource<RegistryValue>("Set execution policy")
            .Path(@"HKLM:\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell")
            .Value("ExecutionPolicy")
            .Data("Unrestricted", RegistryValueKind.String);

        // Install
        context.Resource<PowerShell>("Install Chocolatey")
            .Script("~/install-chocolatey.ps1")
            .Flavor(PowerShellFlavor.PowerShell)
            .RequireAdministrator()
            .Unless("if (Test-Path \"$($env:ProgramData)/chocolatey/choco.exe\") { exit 1 }")
            .After<RegistryValue>("Set execution policy")
            .After<Download>("https://chocolatey.org/install.ps1");

        // Install VSCode via Chocolatey
        context.Resource<ChocolateyPackage>("vscode")
            .Ensure(PackageState.Installed)
            .After<PowerShell>("Install Chocolatey");
    }
}

When we have a Manifest, we need to create a Catalog containing the manifest.
We'll also add a condition that excludes non-Windows environments.

public sealed class MyWindowsComputer : Catalog
{
    public override void Execute(CatalogContext context)
    {
        if (!context.Facts.IsWindows())
        {
            return;
        }

        context.UseManifest<Chocolatey>();
    }
}

To run the application, we need to add an application entry-point and create a CupboardHost.
We must also explicitly add the catalogs to the CupboardHostBuilder instance.

public static class Program
{
    public static int Main(string[] args)
    {
        return CupboardHost.CreateBuilder()
            .AddCatalog<MyWindowsComputer>()
            .Run(args);
    }
}

Now, open up a terminal in administrator mode and execute the build.

Cupboard will show you a summary of what will be changed, which you will have to approve.

WARNING: This will change the state of the current machine.
Are you sure you want to continue? [y/n] (n): _

We're using Cake as a dotnet tool for building. So make sure that you've restored Cake by running the following in the repository root:

After that, running the build is as easy as writing:
