# Dockerfile for Celery Replacement Example
|
|
#
|
|
# This demonstrates running a production-ready application with
|
|
# Gunicorn dirty arbiters replacing Celery for background tasks.
|
|
#
|
|
# Key difference from Celery deployment:
|
|
# - Celery: Needs separate web + worker containers + Redis/RabbitMQ
|
|
# - Dirty: Single container handles both HTTP and background tasks
|
|
