A Pulumi package to safely use randomness in Pulumi programs.

Random Provider

The random provider allows the safe use of randomness in a Pulumi program. This allows you to generate resource properties, such as names, that contain randomness in a way that works with Pulumi's goal state oriented approach. Using randomness as usual would not work well with Pulumi, because by definition, each time the program is evaluated, a new random state would be produced, necessitating re-convergence on the goal state. This provider understands how to work with the Pulumi resource lifecycle to accomplish randomness safely and in a way that works as desired.


This package is available in many languages in the standard packaging formats.

Node.js (Java/TypeScript)

To use from JavaScript or TypeScript in Node.js, install using either npm:

$ npm install @pulumi/random

or yarn:

$ yarn add @pulumi/random


To use from Python, install using pip:

$ pip install pulumi_random


To use from Go, use go get to grab the latest version of the library

$ go get


To use from .NET, install using dotnet add package:

$ dotnet add package Pulumi.Random


For example, to generate a random password, allocate a RandomPassword resource and then use its result output property (of type Output<string>) to pass to another resource.

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

const password = new random.RandomPassword("password", {
    length: 16,
    overrideSpecial: "_%@",
    special: true,
const example = new aws.rds.Instance("example", {
    password: password.result,
