Docker Drupal Cron

A lightweight Docker setup for running Drupal cron jobs via HTTP requests.

Overview

This project provides a containerized cron service that makes HTTP requests to trigger Drupal cron jobs. It's designed to work alongside a Drupal installation running in Docker containers.

Services

• caddy: Web server serving Drupal
• php-fpm: PHP-FPM service for Drupal
• cron: Alpine-based container that periodically calls Drupal's cron endpoint

Configuration

Configure the cron service via environment variables:

environment:
  CRON_SCHEDULE: "*/1 * * * *"  # Run every minute (cron format)
  OPTIONS: "-s drupal/cron/__drupal-cron-hash__"  # Curl options and URL

Usage

Start all services:

docker-compose up -d

Run cron immediately:

docker-compose exec cron /start.sh now

View cron logs:

docker-compose logs -f cron

Setup

1. Update OPTIONS environment variable with your Drupal cron URL
2. Adjust CRON_SCHEDULE as needed
3. Start the services with docker-compose up -d

The cron service will automatically begin making requests to your Drupal installation based on the configured schedule.
