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

# Docker Compose

A single container is launched with a single `docker` command. An application requiring several containers, like Node.js, NGINX, and MongoDB, must be started with three commands. You could launch each in three terminals in the correct order (first MongoDB, then the Node.js application, then NGINX).

Docker Compose is a tool for managing multiple containers with associated volumes and networks. A single configuration file, normally named `docker-compose.yml`, defines the containers and can override Dockerfile settings where necessary.

It's practical to create a Docker Compose configuration for development. You could also create one for production, but there are better options.



Learn about Compose and how Docker facilitates orchestration.
