Dockerfile Additions for Supervisor
# ─── Supervisor Installation ────────────────────────────
# Alpine-based image
RUN apk add --no-cache supervisor
# Debian-based image
# RUN apt-get update && apt-get install -y supervisor && rm -rf /var/lib/apt/lists/*
# Create directories
RUN mkdir -p /var/log/supervisor /etc/supervisor/conf.d
# Copy Supervisor configuration
COPY docker/supervisor/supervisord.conf /etc/supervisor/supervisord.conf
COPY docker/supervisor/conf.d/ /etc/supervisor/conf.d/
# Start Supervisor as the main process
CMD ["/usr/bin/supervisord", "-c", "/etc/supervisor/supervisord.conf"]

Generation Instructions
Identify processes needed:
- PHP-FPM (web requests)
- Queue workers (Symfony Messenger / Laravel Queue)
- Scheduler (cron replacement)
- Custom daemons
Choose deployment model:
- All-in-one (Supervisor manages all): simpler, good for small projects
- Separate containers (one process each): recommended for production
Generate configurations:
- Main supervisord.conf
- Per-process conf.d/ files
- Dockerfile additions
Tune parameters:
- numprocs for worker concurrency
- memory-limit and time-limit for workers
- stopwaitsecs for graceful shutdown
- startretries for resilience
Usage
Provide:
- Framework (Symfony/Laravel)
- Processes to manage (web, workers, scheduler)
- Worker count and memory limits
- Deployment model (all-in-one or separate)
The generator will:
- Create supervisord.conf with proper settings
- Generate per-process configuration files
- Add Dockerfile instructions for Supervisor
- Configure logging to stdout/stderr for Docker
