Supervisor

Process Architecture

Supervisor manages all processes in the container. If any critical process exits, Supervisor can restart it automatically.

Configuration

[supervisord]
nodaemon=true
user=root
logfile=/var/log/supervisor/supervisord.log
pidfile=/var/run/supervisord.pid

[program:nginx]
command=/usr/sbin/nginx -g 'daemon off;'
autostart=true
autorestart=true
priority=10
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0
stderr_logfile=/dev/stderr
stderr_logfile_maxbytes=0

[program:php-fpm]
command=/usr/local/sbin/php-fpm -F
autostart=true
autorestart=true
priority=5
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0
stderr_logfile=/dev/stderr
stderr_logfile_maxbytes=0

[program:horizon]
command=/usr/bin/php /var/www/html/artisan horizon
autostart=true
autorestart=true
user=www-data
redirect_stderr=true
stdout_logfile=/var/www/html/storage/logs/horizon.log
stopwaitsecs=3600

[program:reverb]
command=/usr/bin/php /var/www/html/artisan reverb:start
autostart=true
autorestart=true
user=www-data
redirect_stderr=true
stdout_logfile=/var/www/html/storage/logs/reverb.log

[program:scheduler]
command=/bin/sh -c "while [ true ]; do php /var/www/html/artisan schedule:run --verbose --no-interaction & sleep 60; done"
autostart=true
autorestart=true
user=www-data
redirect_stderr=true
stdout_logfile=/var/www/html/storage/logs/scheduler.log

Process Priority

Process	Priority	Reason
php-fpm	5	Must start first
nginx	10	Depends on FPM
horizon	15	Can start after web
reverb	15	Can start after web
scheduler	20	Lowest priority

Restart Behavior

• autorestart=true - Process restarts if it exits
• stopwaitsecs=3600 - Horizon gets 1 hour to finish jobs on shutdown
• Logs to stdout/stderr for container log aggregation
