Develop a local WordPress theme using Docker

Learn how to link a local WordPress theme in your docker instance

11 Oct, 2021 ยท 2 min read

A while ago, we learned how easy it could be to set up WordPress using Docker. However, this setup didn't allow for customization.

So let's have a look at how we could develop our WordPress theme using Docker.

The file structure

As we could see before, all we needed was a docker-compose.yml file.

In our new setup, we want to include a themes folder without specific themes.

In the example case, we have one theme called fooserama.

Custom WordPress theme

Note: This will overwrite all themes, so you will lose any themes you already loaded in WordPress (including the default ones)

Changing the Dockerfile

Next up, we have to change our docker-compose.yml file to reflect this data.

The first part we want to change is the volume part for the WordPress image. Before, this was set up like so:

wordpress:
	volumes:
	  - wordpress_data:/var/www/html

And then in the volumes section, we had this:

volumes:
  db_data: {}
  wordpress_data: {}

What we want is to change the volumes for the WordPress image like so:

wordpress:
	volumes:
	  - ./themes:/var/www/html/wp-content/themes

And we want to remove this link for the volumes so it will look like this:

volumes:
  db_data: {}

If we reboot out the Docker image, we should have our custom theme available on the WordPress website.

docker-compose up -d

Custom WordPress theme loaded in Docker

This same approach could be used to handle plugins or even uploads if you wanted to.
