Use Docker to create a local WordPress development environment

These files are used in a tutorial I created on my website, www.massolit-media.com that introduces the reader to Docker and demonstrates how you can create your own WordPress environment using Docker, Docker Compose, and Dockerfiles.

An overview of the tutorial: Use Docker to create a local WordPress development environment

The five articles that this tutorial consists of are designed to be read and completed in sequence, but they do not have to be:

1. WordPress and Docker: Introduction to Docker and basic Docker commands – Get started using Docker on the command line.
2. WordPress and Docker: Using Docker Compose – Create your own Docker application that uses three containers to create a WordPress site that you can deploy wherever you can run Docker and Docker Compose.
3. WordPress and Docker: Customizing a Docker container – Open up some containers and work on them. Then save your work.
4. WordPress and Docker: Build custom images with Dockerfiles – Build containers with an automated workflow defined in a text file so the container has what you want in it without you having to open it.
5. WordPress and Docker: Putting it all together – Making some final changes to a Docker Compose file to deploy the entire application with a single command.

Prerequisites

This tutorial requires you to have some familiarity with and knowledge of the Linux command line, including text editors like Vi/Vim or Nano. I created this tutorial using:

• A MacBook Pro (macOS 10.14)
• The macOS Terminal with Zsh.
• A text editor. I like Visual Studio Code.
• Docker Desktop for Mac. Docker Community Edition, the free version of Docker, is available for Windows and Linux and can also be run on AWS or Azure. Find Docker CE for your platform.
• This GitHub repo.
