Create a new directory called google-account-creator and navigate into it:

mkdir google-account-creator
cd google-account-creator

Create a creds directory to store your Google account credentials:

mkdir creds

Create a src directory to store your Node.js application code:

mkdir src

Navigate to the src directory:

cd src

Create a new file called index.js and paste the following code into it:

const puppeteer = require('puppeteer');
const randomstring = require('randomstring');

(async () => {
  const browser = await puppeteer.launch({ args: ['--no-sandbox'] });
  const page = await browser.newPage();
  await page.goto('https://accounts.google.com/signup');

  const firstName = randomstring.generate();
  const lastName = randomstring.generate();
  const username = randomstring.generate({ length: 8, readable: true });
  const password = randomstring.generate({ length: 10, readable: true });

  await page.type('input[name="firstName"]', firstName);
  await page.type('input[name="lastName"]', lastName);
  await page.type('input[name="Username"]', username);
  await page.type('input[name="Passwd"]', password);
  await page.type('input[name="ConfirmPasswd"]', password);

  await page.click('div[jsname="Cuz2Ue"] button');

  console.log(`Account created with the following details:\nUsername: ${username}\nPassword: ${password}`);

  await browser.close();
})();

Create a new file called package.json and paste the following code into it:

{
  "name": "google-account-creator",
  "version": "1.0.0",
  "description": "Create a Google account using Puppeteer",
  "main": "index.js",
  "dependencies": {
    "puppeteer": "^10.2.0",
    "randomstring": "^1.4.0"
  }
}

Create a new file called Dockerfile and paste the following code into it:

FROM node:14-alpine
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
CMD ["npm", "start"]

Create a new file called docker-compose.yml and paste the following code into it:

version: "3.9"
services:
  app:
    build: .
    environment:
      - PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=true
      - PUPPETEER_EXECUTABLE_PATH=/usr/bin/chromium-browser
    volumes:
      - ../creds:/app/creds
    networks:
      - backend

networks:
  backend:
    driver: bridge

Now you can run docker-compose up -d from the google-account-creator directory to start the application in a Docker container. The creds directory will be mounted into the container so that your credentials can be accessed by the Node.js application.
