How to Set Up a Local WordPress Environment with Docker: A Step-by-Step Guide

Setting Up a Local WordPress Environment with Docker: A Beginner's Guide

Docker has revolutionized how developers test and develop projects, allowing for isolated environments where each component lives in a separate container. In this tutorial, we'll walk through the steps to set up a local WordPress environment using Docker.

Prerequisites

Before you begin, ensure you have the following installed:

  1. Docker
  2. Docker Compose

If not, download both from the official Docker website.

Step-by-Step Guide

1. Create a Workspace:

Start by making a directory for your WordPress project.

Loading...

Open this directory in an editor of your choice. Here, we'll use VS Code:

Loading...

2. Docker Compose YAML File:

Create a file named docker-compose.yml. This file will define our WordPress and MySQL services.

Database Service:

Define the database service using this YAML code:

Loading...

This code sets up two services: a database service using MySQL and a WordPress service. The WordPress service communicates with the database using environment variables.

3. Running Your WordPress Instance:

With the configurations set, start your services:

Loading...

After the command executes, access your WordPress site by navigating to localhost:8000 in your browser.

4. WordPress Setup on Local Machine:

Follow the on-screen instructions:

  • Choose a language.
  • Set the site title.
  • Define an admin username and password.

5. Accessing WordPress Files:

Thanks to the volume mapping in our docker-compose.yml, the wp-content directory from the Docker container syncs with your local machine. This means any plugins, themes, or other files you add locally will reflect in the Docker WordPress instance and vice versa.

6. Stop and Start Your Services:

When done, you can stop the services using:

Loading...

To start them up again:

Loading...

Conclusion

Congratulations! You now have a fully functional local WordPress environment set up using Docker. This setup ensures a safe space to experiment, develop, and test without affecting a live site. Remember to always consult the Docker Hub or other resources if you're unsure about configurations or variables. Happy coding!
