Copy Custom WordPress Theme with Docker Composer

I am running WordPress with Nginx in Docker using Docker Compose and I want to copy over a custom theme. Right now in my docker-compose.yml file I have,

  wordpress:
depends_on:
  - db
image: wordpress:5.1.1-fpm-alpine
container_name: wordpress
restart: unless-stopped
env_file: .env
environment:
  - WORDPRESS_DB_HOST=MYHOST
  - WORDPRESS_DB_USER=$MYSQL_USER
  - WORDPRESS_DB_PASSWORD=$MYSQL_PASSWORD
  - WORDPRESS_DB_NAME=MYDB
volumes:
  - ./plugins/advanced-custom-fields:/var/www/html/wp-content/plugins/advanced-custom-fields
  - ./themes/mytheme:/var/www/html/wp-content/themes/mytheme
It kind of works. The theme copies over some of the php files from the theme folder but it doesn't copy over any of the stylesheets or any of the images in the /img/ folder.

Any ideas?

Thanks in advance!

Hello,

Actually the snippet that you’ve provided looks correct. Have you manually checked if the files are actually there?

You could do that by attaching to the running container with docker exec and listing the contents of the /var/www/html/wp-content/themes/mytheme directory.

To do that you could run the following:

docker ps -a

Find the ID of your container and then run:

docker exec -it your_container_id bash

Then once you are attached run:

ls -l /var/www/html/wp-content/themes/mytheme

If the files are actually there make sure that the permissions are correct.

Then to detach press CTRL+P+Q.

You could also check the logs of the container for any errors:

docker logs your_container_id 

Hope that this helps!

  • Thanks Bobby! By any chance do you know what permissions it should have and how to set them via Docker Compose?

    Thanks!

    • Hi Justin,

      I believe that for the wordpress:5.1.1-fpm-alpine image the ownership of the files should be set to www-data for both the owner and the group.
