Pulumi TypeScript Stack References to µs Converter

This program converts stack references in Pulumi TypeScript projects to µs remotes and wishes, and stack outputs to µs offers.

Usage

You can use this program with a local Node.js setup or within an interactive shell session of a Node.js docker container, which you can start in this directory:

docker run --rm -ti -v $(pwd):/var/converter node:16.2.0-alpine3.13 /bin/sh /var/converter/init-container.sh

The container is automatically disposed when you exit the shell.

Install Dependencies

npm install

Run the Converter

node translate.js

This executes the conversion on all files in ./repos. Please note that the conversion is not idempotent and, thus, should only be executed once.

Example

To give an example, we provide the aws-ts-stackreference project from the Pulumi examples in ./repos/example. Running the converter once, converts all three included programs. For instance, ./repos/example/team/index.ts gets converted to the following content:

// Copyright 2016-2019, Pulumi Corporation.  All rights reserved.

import * as aws from "@pulumi/aws";
import * as pulumi from "@pulumi/pulumi";
import * as mjuz from '@mjuz/core/resources'

/**
 *   company
 *   └─ department
 *      └─ team
 */

const config = new pulumi.Config();

const companyStack = new mjuz.Remote<{ companyName: any }>(config.require("companyStack"),
            { host: config.require('companyStackHost'), port: config.require('companyStackPort') });
const departmentStack = new mjuz.Remote<{ departmentName: any }>(config.require("departmentStack"),
            { host: config.require('departmentStackHost'), port: config.require('departmentStackPort') });

const combinedTags = {
    /* from company stack    */ company: companyStack.wishes.exports.companyName,
    /* from department stack */ department: departmentStack.wishes.exports.departmentName,
    /* from team config      */ team: config.require("teamName"),
    "Managed By": "Pulumi",
};

const amiId = aws.getAmi({
    owners: ["099720109477"], // Ubuntu
    mostRecent: true,
    filters: [
        { name: "name", values: ["ubuntu/images/hvm-ssd/ubuntu-bionic-18.04-amd64-server-*"] },
    ],
}, { async: true }).then(ami => ami.id);

const instance = new aws.ec2.Instance("tagged", {
    ami: amiId,
    instanceType: "t2.medium",
    tags: combinedTags,
});

export const instanceId = instance.id;
export const instanceTags = instance.tags;

new mjuz.Offer(
    new mjuz.RemoteConnection('beneficiary', { host: config.require('beneficiaryHost'), port: config.require('beneficiaryPort') }), 
    'exports', { instanceId, instanceTags })
