Convert String Array to Pulumi StringArrayInput

Introduction

In this guide, we will demonstrate how to convert a standard string array to a Pulumi StringArrayInput in TypeScript. Pulumi is an Infrastructure as Code (IaC) tool that allows you to define and manage cloud resources using familiar programming languages. The StringArrayInput type is part of Pulumi’s input types, which are used to define resource properties that can accept dynamic values.

Step-by-Step Explanation

Step 1: Import Pulumi

First, we need to import the Pulumi library in our TypeScript file. This will give us access to the necessary types and functions.

Step 2: Define the String Array

Next, we define a standard string array that we want to convert to a StringArrayInput.

Step 3: Convert to StringArrayInput

We then use the pulumi.output function to convert the string array to a StringArrayInput. This function wraps the array in a Pulumi Output object, which is compatible with StringArrayInput.

Step 4: Use the StringArrayInput

Finally, we can use the StringArrayInput in our Pulumi resource definitions. This allows us to pass dynamic values to resource properties.

Key Points

• Pulumi is an IaC tool that uses familiar programming languages to define and manage cloud resources.
• The StringArrayInput type is used to define resource properties that can accept dynamic values.
• The pulumi.output function is used to convert a standard string array to a StringArrayInput.
• This conversion allows us to pass dynamic values to Pulumi resource properties.

Conclusion

In this guide, we demonstrated how to convert a standard string array to a Pulumi StringArrayInput in TypeScript. By following the steps outlined above, you can easily use dynamic values in your Pulumi resource definitions. This approach leverages Pulumi’s powerful input types to create flexible and dynamic infrastructure configurations.

Full Code Example

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

// Step 2: Define the String Array
const stringArray: string[] = ["value1", "value2", "value3"];

// Step 3: Convert to StringArrayInput
const stringArrayInput: pulumi.Input<pulumi.Input<string>[]> = pulumi.output(stringArray);

// Step 4: Use the StringArrayInput
const bucket = new aws.s3.Bucket("my-bucket", {
    tags: stringArrayInput.apply(values => ({
        Tag1: values[0],
        Tag2: values[1],
        Tag3: values[2]
    }))
});

export const bucketName = bucket.id;
