The easiest thing we can do is use Puppeteer to open a webpage and take a screenshot of it. A Minimal Puppeteer Exampleīefore we embark upon our Docker journey, we need a simple Puppeteer program we can test with. In this article, we’ll see why this combination is problematic and how to solve it. However, since deploying a browser is fundamentally more complicated than your average API, Puppeteer and Docker are a little tricky to get working together.
