A small framework for creating flexible Pulumi programs.
Table of Contents
Installation
npm install --save @webiny/pulumi
Or if you prefer yarn:
yarn add @webiny/pulumi
Overview
The @webiny/pulumi
package enables creation of flexible Pulumi apps (programs).
More specifically, a Pulumi app not only encapsulates the essential Pulumi program code defined by developers, but also, once defined, provides a way to adjust any defined cloud infrastructure resource configuration and even add new resources into the mix.
This is useful when you just want to export a simple constructor function to the user, and not bother them with all the internals. And, as mentioned, in those rare cases when the user actually needs to perform further adjustments, a Pulumi app provides a way to do it.
💡 TIP
Pulumi apps are heavily used in real Webiny projects. As mentioned, this is because of their ability to abstract the actual cloud infrastructure code from the user, and, at the same time, provide a way for the user to perform adjustments when needed.
The following example shows how a Pulumi app looks in the actual code:
import createXyzApp from "@webiny/xyz-app";
export = async () => {
const xyzApp = createXyzApp({
pulumi: app => {
app.resources.bucket.config.acl(aws.s3.CannedAcl.Private);
app.resources.bucket.config.forceDestroy(true);
}
});
return xyzApp.run();
};

Type Declaration
export interface CreatePulumiAppParams<TResources extends Record<string, unknown>> {
name: string;
path: string;
config?: Record<string, any>;
program(app: PulumiApp): TResources | Promise<TResources>;
}
export declare function createPulumiApp<TResources extends Record<string, unknown>>(params: CreatePulumiAppParams<TResources>): PulumiApp<TResources>;
Creates a new Pulumi app.
import * as aws from "@pulumi/aws";
import { createPulumiApp } from "@webiny/pulumi";
export interface CreateMyAppParams {
pulumi?: (app: ReturnType<typeof createMyApp>) => void;
}
const createMyApp = (projectAppConfig: CreateMyAppParams) => {
const app = createPulumiApp({
name: "my-app",
path: "relative/path/from/cwd",
program: async app => {
const bucket = app.addResource(aws.s3.Bucket, {
name: "my-app",
config: {
acl: aws.s3.CannedAcl.PublicRead,
forceDestroy: false,
website: {
indexDocument: "index.html",
errorDocument: "index.html"
}
}
});
app.addOutputs({
appStorage: bucket.output.id
});
return {
bucket
};
}
});
if (projectAppConfig.pulumi) {
projectAppConfig.pulumi(app);
}
return app;
};
