Automate Your Infrastructure with Pulumi

Managing infrastructure can be frustratingly hard. Combing through byzantine interfaces with poor documentation and hidden features, clicking through hundreds of menus - these experiences are all too familiar to DevOps engineers using AWS. A DevOps engineer's worst fear is that the business will ask for a new instance of the application for a client, and they will have to repeat all those manual steps again. (Hopefully in the correct order, and not forgetting anything along the way!)

At Hashrocket we are big fans of automation, and part of that means we use the

import * as Pulumi from '@pulumi/pulumi';
import * as DigitalOcean from '@pulumi/digitalocean';
import * as fs from 'fs';

const projectName = Pulumi.getProject();
const config = new Pulumi.Config();

const sshPubKeyFilename = config.require('sshPubKeyFilename');
const publicKey = fs.readFileSync(sshPubKeyFilename).toString();
