Docker-Compose definition for a light Wordpress Stack

docker-compose.yml

# A Docker Compose setup for running most Wordpress environments
#
# Setup:
# 1. Configure wp-config.php to either pull the environment variables in 
#    services.web.environment or use the same settings.
# 2. Optionally put a database dump in the project root which will get imported
#    on first project boot. This will remain persistent, so if you need to wipe
#    the database, `docker volume ls` will help you find it and 
#    `docker volume rm [volume name]` to remove it.
# 3. `docker-compose up`
