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

# Necessary services

The required files are provided for editing. The changes you need to make in them are also explained in this lesson. 

Three services are needed in our main Compose file, namely, `mongodb`, `nodejs`, `nginx`.

## Docker network:

Connect the three containers/services with a Docker network named `quiznet`.


## MongoDB database (`mongodb` container)

Add the following configurations under the service of `mongodb` in **_`docker-compose.yml`_**: 

1. Define the variables for accessing the database with the user ID `quizuser` and password `quizpass`. 
1. Specify the image, name of the container, and network. Also, expose the default port of MongoDB.
1. Specify the Docker volume, `quizdata`, for question storage. The folders `/data/db` should be mounted to `quizdata`.
1. Also add `logging` property with `driver` set as `none`.

This completes our setting up of `mongodb`.

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

### Making Dockerfile for nodejs

Specify the Dockerfile commands that you need for your Node application in **_`/nodejs/nodejs.Dockerfile`_**. The Docker file should include the commands for specifying the image, environment variables, and work directories. There should also be commands for setting the user, copying required files, installing application modules, building `npm`, sharing the volume, and exposing the port of `8000`. Finally, there should be a command to launch the application

> 📌 You can add the following in addition to the commands added:
>```Dockerfile
>##environment variables
>ENV HOME=/home/node/app
>ENV PATH=${PATH}:${HOME}/node_modules/.bin
>#share volume
>VOLUME ${HOME}/static
>```

> 📌 We are building Dockerfile for development purposes. Make sure to set the required environment variables.

### Adding `nodejs` to Compose

Add the following configurations under the service of `nodejs` in **_`docker-compose.yml`_**: 
1. Add the environment variable, name of the container, dependencies, and network. Specify the command for the `npm`, and expose the required ports.

1. Specify the Dockerfile to be used and the following volumes:
   ```yaml
   - ./nodejs:/home/node/app
   - nodejsfiles:/home/node/app/static
   - nodejsfiles:/home/node/app/.config
   - nodejsfiles:/home/node/app/.npm
   - nodejsfiles:/home/node/app/node_modules
   ```

This completes our setting up of `nodejs`.

## NGINX reverse proxy (`nginx` container)

An NGINX web server container will be used to serve files from the shared `static` volume. This is more efficient than serving via Express.js as NGINX is faster. The NGINX is prefered for its performance and is also easy to configure. 

Other HTTP requests (such as the `/question` endpoint) are forwarded to the `nodejs` container. NGINX will act as a #concept=reverseProxy#reverse proxy.#concept#


### Making Dockerfile for NGINX

Specify the Dockerfile commands that you need for your Node application in **_`/nginx/nginx.Dockerfile`_**. Include an image, copy the configuration file to the `/etc/nginx/nginx.conf` in the container, and expose its default port.

### Adding `nginx` to Compose

Add the following configurations under the service of `nginx` in **_`docker-compose.yml`_**: 

1. Specify the Dockerfile to be used, name of the container, dependency, network, and ports.
1. Also add `logging` property with `driver` set as `none`.
