Speed up your local WordPress development with Docker on Windows

If you prefer watching the experiment, here is the video:

Most of us when beginning developing with Docker usually mount from a local path to a path inside the containers since it's the simplest solution. However, this simplicity comes with a cost:

Speed!

Especially when you are developing on Windows.

You see, Docker on Windows, despite all the efforts cannot compare to what it's like on Linux. I have my WP sites on Linux and it loads super fast.

From what I learn, mounting the local directory to a container on Windows can make app loads very slow, not just WordPress.

So, I decided to give it a try: move codes, database to a volume.

And guess what? Speed improved immensely.

The old setup

Here is the old setup:

version: '3.8'

services:
  wp:
    image: webdevops/php-apache:7.4
    container_name: wp
    restart: always
    volumes:
      - D:\Data\dev\wordpress\main\:/app
    ports:
      - 8888:80
  db:
    image: mariadb:10.5.3
    container_name: db
    restart: always
    volumes:      
      - ./db:/var/lib/mysql
    environment:
      MYSQL_ROOT_PASSWORD: root

Enter fullscreen mode Exit fullscreen mode

You see the problem? Both db and the WordPress code are mounted from a local directory on the host machine. Thus, the site loads super slow.

The new setup

version: '3.8'

services:
  wp:
    image: webdevops/php-apache:7.4
    container_name: wp
    restart: always
    volumes:
      - wordpress:/app

    ports:
      - 8888:80
  db:
    image: mariadb:10.5.3
    container_name: db
    restart: always
    volumes:
      - db:/var/lib/mysql

    environment:
      MYSQL_ROOT_PASSWORD: root

volumes:
  db:
  wordpress:
Enter fullscreen mode Exit fullscreen mode

Now, I created two volumes, one for db and one for the WordPress code. Guess what? The site isn't slow anymore.

Give it a try

Sorry but I don't get the difference.
