A Docker container configuration for WordPress via Docker Compose.

docker-compose.wordpress.coredev.yml

version: '2'

services:

  wordpress:
    image: wordpress
    ports:
      - 8888:80
    environment:
      WORDPRESS_DB_PASSWORD: password
    volumes:
      # WordPress and Jetpack are checked out from their git repositories
      - ./wordpress:/var/www/html/
      - ./jetpack:/var/www/html/wp-content/plugins/jetpack/
      - ./opcache-recommended.ini:/usr/local/etc/php/conf.d/opcache-recommended.ini

opcache-recommended.ini

# Empty file. Recommended to help with better caching locally.

uploads.ini

file_uploads = On
memory_limit = 64M
upload_max_filesize = 64M
post_max_size = 64M
max_execution_time = 600

The docker-compose... file should be renamed to docker-compose.yaml when loading into a project. The volumes can be adjusted on a per-project bases to better fit what you're working on - theme dev, plugin dev, etc.

The uploads.ini file allows for larger upload files than what you get by default.

I'm not exactly sure about what the opcache-recommended.ini file does. As I understand it, it's just an empty file that helps with caching for your local setup. I may need to remove the comment there but I had to add it for it to be saved here (Gists don't allow empty files). I will research this one a bit more and leave another note when I find more details.
