There was a problem hiding this comment.
Hey there - I've reviewed your changes - here's some feedback:
- You’ve added empty .dockerignore and Dockerfile.frontend files—either populate them with the appropriate ignore rules and frontend build steps or remove them until you’re ready to avoid build failures.
- The volumes media_files and static_files are declared but not mounted by any service—either remove them or wire them up if you intend to persist uploads and static assets.
- The custom 'develop' section in the django-web-backend service isn’t a standard Docker Compose field; consider moving those development-specific mounts into a compose override file (docker-compose.override.yml) for better compatibility.

<issue_to_address>
Healthcheck for RabbitMQ uses rabbitmq-diagnostics, which may not be present in all images.
Verify that the image includes rabbitmq-diagnostics, or switch to a more universally available healthcheck command like rabbitmqctl or a TCP check to ensure reliability.

<issue_to_address>
Returning 200 for 405 errors may mask underlying issues.
Returning 200 for 405 errors can obscure real issues and complicate debugging. Please confirm if this behavior is intentional for all affected endpoints.

</code_context>
<issue_to_address>
Gunicorn is used for serving Django, but no worker configuration is specified.
Specify worker count and timeout for Gunicorn to improve performance and stability under load.

<issue_to_address>
Celery worker concurrency is hardcoded to 4.
Recommend using an environment variable for concurrency to allow flexibility across deployments.
