Azure Functions Docker image with support for Puppeteer

Why use this image?

You probably want to use Puppeteer in your Azure Function. This Docker image got you covered.

Usage

Initialize a new project for your Azure Functions:

func init --docker

Update the Dockerfile with the following contents:

FROM estruyf/azure-function-node-puppeteer

COPY . /home/site/wwwroot

Using Puppeteer

Once you create a new Azure Function, you can use it like this sample:

const puppeteer = require('puppeteer');

module.exports = async (context, req) => {    
    const browser = await puppeteer.launch({
        args: [
            '--no-sandbox',
            '--disable-setuid-sandbox'
        ]
    });

    const page = await browser.newPage();
    await page.goto('https://www.eliostruyf.com');
    const pageTitle = await page.title();
    await browser.close();

    context.res = {
        // status: 200, /* Defaults to 200 */
        body: `Page title: ${pageTitle}`
    };
};


## Publishing to Docker hub
One time only:
 - Create repo on docker hub
 - Make sure your docker user can write to it
 - `docker login` (with your hub.docker.com credentials on your terminal)

Each time you want to publish:
 - `docker build -t <org>/azure-function-node-puppeteer:1.0.0 .`
   - `-t ...` tags this image
   - `.` the current directory with the Dockerfile in it
 - Copy the tag to other tags:
   - `docker tag <org>/azure-function-node-puppeteer:1.0.0 <org>/azure-function-node-puppeteer:1`
   - `docker tag <org>/azure-function-node-puppeteer:1.0.0 <org>/azure-function-node-puppeteer:1.0`
   - `docker tag <org>/azure-function-node-puppeteer:1.0.0 <org>/azure-function-node-puppeteer:latest`
 - Push all the tags to Dockerhub:
   - `docker push <org>/azure-function-node-puppeteer:1.0.0`
   - `docker push <org>/azure-function-node-puppeteer:1.0`
   - `docker push <org>/azure-function-node-puppeteer:1`
   - `docker push <org>/azure-function-node-puppeteer:latest`
