How Do I Build a Command Local Command With Pulumi?

In this guide, we will build a local command using Pulumi in TypeScript. Pulumi is an Infrastructure as Code (IaC) tool that allows you to define and manage cloud resources using familiar programming languages. In this example, we will use Pulumi to execute a local command on our machine. This can be useful for running scripts, automating tasks, or performing any other command-line operations as part of your Pulumi deployment.

Introduction

Pulumi is a powerful IaC tool that enables developers to define and manage cloud infrastructure using programming languages like TypeScript, Python, Go, C#, and Java. In this guide, we will demonstrate how to use Pulumi to execute a local command on your machine. This can be particularly useful for running custom scripts, automating tasks, or performing any other command-line operations as part of your Pulumi deployment.

Step-by-Step Explanation

Step 1: Install Pulumi and Create a New Project

1. Install Pulumi CLI by following the instructions on the Pulumi website.
2. Create a new Pulumi project by running pulumi new typescript in your terminal and following the prompts.

Step 2: Install the Pulumi Command Package

1. Navigate to your project directory.
2. Install the Pulumi Command package by running npm install @pulumi/command.

Step 3: Define the Local Command Resource

1. Open the index.ts file in your project directory.
2. Import the necessary Pulumi and Pulumi Command modules.
3. Define a new local command resource using the local.Command class from the Pulumi Command package.
4. Specify the command to be executed and any necessary arguments or environment variables.

Step 4: Run the Pulumi Program

1. Run pulumi up in your terminal to preview and deploy the changes.
2. Confirm the deployment to execute the local command.

Key Points

• Pulumi allows you to define and manage cloud infrastructure using familiar programming languages.
• The Pulumi Command package enables you to execute local commands as part of your Pulumi deployment.
• You can specify the command to be executed, along with any necessary arguments or environment variables.
• Running pulumi up will preview and deploy the changes, executing the specified local command.

Conclusion

In this guide, we demonstrated how to use Pulumi to execute a local command on your machine using TypeScript. By leveraging the Pulumi Command package, you can easily integrate custom scripts and command-line operations into your Pulumi deployments. This can help automate tasks, streamline workflows, and enhance the overall efficiency of your infrastructure management.

Full Code Example

import * as pulumi from "@pulumi/pulumi";
import * as command from "@pulumi/command";

const localCommand = new command.local.Command("localCommand", {
    create: "echo 'Hello, Pulumi!'",
});

export const stdout = localCommand.stdout;
export const stderr = localCommand.stderr;
