Docker is the most useful web development tool you’re not using. This course is your guide for building all kinds of web applications with Docker.

You will be introduced to Docker basics including its architecture, images, and containers. Then you'll run various databases and view them via CLI or Adminer. Next, you will learn how easy it is to use WordPress with Docker. After that is the Node.js app and its live editing and debugging with Chrome's devTools. Finally, you will make your own project to practice your Docker knowledge.

By the end of the course, you will be able to confidently use Docker in any of your further projects.

Docker for Web Developers

# Solution overview

An overview of the solution is provided below. More details will be discussed in the coming lessons.

## MongoDB database (`mongodb` container)

This container should use a Docker volume (`quizdata`) for question storage and expose the database on port `27017`. Create a collection named `quiz` in the `quiz` database that is accessed with the user ID `quizuser` and password `quizpass`.


## Node.js application (`nodejs` container)

The Node.js container has two functions:

1. `index.js` should launch an Express.js application exposed on port `8000`, which:

   * Fetches questions and answers from the [Open Trivia Database API](https://opentdb.com/) on start-up. These should be formatted and stored in the MongoDB database.

   * Provides a single `/question` endpoint. This should query the database and return the details of the next question as JSON-encoded data.

   During development, any changes to the Node.js files trigger an application restart using [Nodemon](https://nodemon.io/).

1. Client-side HTML, CSS, and JavaScript implement the application logic to fetch questions and keep score. Source code contained in the `src` directory is built using npm scripts, which run [pug](https://pugjs.org/), [PostCSS](https://postcss.org/), and [Rollup.js](https://rollupjs.org/). The resulting files are output to a `static` directory (a shared Docker volume).

   In production, this processing occurs when the Docker image is built. During development, changes to `src` files in the host's project directory trigger a `static` file rebuild and source maps are appended.


## NGINX reverse proxy (`nginx` container)

An NGINX web server container serves files from the shared `static` volume. This is more efficient than serving via Express.js.

Other HTTP requests (such as the `/question` endpoint) are forwarded to the `nodejs` container. NGINX acts as a reverse proxy.
