如何用Docker开发WordPress？能否仅通过Docker容器开发WP自定义主题？

Yes, you absolutely can build a custom WordPress theme using only your existing Docker container—no local WordPress installation required. Here’s the practical, working solution you’ve already put in place (and it’s a go-to approach for this exact scenario):

• Update your docker-compose.yml for the WordPress service by adding a volume mapping to sync your local filesystem with the container’s core WP directory:

  wordpress:
    # Keep your existing config (image, ports, environment variables, etc.)
    volumes:
      - ./wordpress:/var/www/html
  

• Create the local sync directory on your machine:

  mkdir wordpress
  

• Rebuild and restart your Docker stack to activate the volume sync:

  docker-compose build
  docker-compose up -d
  

Once this is done, the entire WordPress filesystem from your container will mirror to your local ./wordpress folder. You can now head to ./wordpress/wp-content/themes on your local machine, create and edit your custom theme files with your preferred code editor, and every change will automatically reflect in the running Docker-hosted WordPress instance. This lets you leverage your local development tools while using the Docker environment for real-time testing.
