How Does Docker Improve Local WordPress Development?

You really only need Docker; no need for PHP or MySQL installations on your system. I suggest trying out an AI CLI tool like Claude Code or Codex. It could help you with your Docker setup directly in your terminal for your specific needs.

I recommend familiarizing yourself with a few Docker concepts. Here’s a quick breakdown:

- **Images**: These are like installation ISOs for your apps; you pull them from Docker Hub for WordPress or MySQL.
- **Containers**: Running instances of your images.
- **Volumes**: Data stored on your host and accessible in the container for data persistence.
- **Networks**: Manage how your containers communicate.

You'll never have to manually install MySQL or download WordPress again—just create a docker-compose file, and it's all set up with minimal effort!

Docker offers some great advantages, like creating a consistent environment that's easy to set up and tear down for testing. If you end up deploying with containers, you can ship everything you need without worrying about dependencies later. While you could technically run multiple WordPress instances on one container, it's better to have separate containers for each site along with their databases for better isolation. The learning curve can be a challenge at first, but it's worth it for speeding up your project setup in the long run.

The main benefit of Docker is containerization. You can develop your app, pack it into a container image, and deploy it easily. With Docker, you can grab official WordPress and MySQL images, which simplifies setup—just mount your files to the container. If WordPress releases an update, you can quickly pull the new image and update your container without much hassle. Overall, Docker makes deploying and maintaining your software much easier compared to just using PHP directly.

Make sure you're running everything within Docker. It seems like you installed Docker but ran everything else separately. Check if there’s a WordPress Docker image you can use. And if you're setting this up at home, consider why you're using Docker instead of something more straightforward.
