Does the docker version of Dify have a Cron?

[ghost]

I built Python code API to use as a tool to create PDFs. But instead of having to have a external service running I wanted to try to integrate it into dify. I can do that pretty easily but the one thing I don't know is whether dify has any internal cron inside his docker container. Because there needs to be a way to delete PDFs over time so they don't build up. Does anyone know if there is a Cron? And if so were the related files are located?
