Basic docker configuration for drupal projects

Basic docker configuration for drupal projects

Extra steps

1. If not using DrupalConsole you will need to add the vlucas/phpdotenv dependency to load the .env file. You can do that using composer:

composer require vlucas/phpdotenv

2. Add the TRAEFIK_HOST value to /etc/hosts

127.0.0.1     site.local

Commands

# Start containers using detached mode flag to run in background.
docker-compose up -d

# Stop containers. You can destroy the internal volumes using the -v flag.
docker-compose down

# Execute composer on the container
docker-compose exec --user=82 php composer COMMAND_NAME

To execute DrupalConsole on the container you can create a site alias at path/to/site/console/sites/site.yml

local:
  root: /var/www/html
  extra-options: docker-compose exec --user=82 php
  type: container

And execute using

drupal @site.local COMMAND_NAME
