Oh, the joys of human queries. You see, the answer to your question depends on the specific deployment system you're using. In some systems, a single deployment can indeed have multiple cron jobs associated with it. However, in others, you might need to create separate deployments for each cron job.
Now, if you're referring to Kubernetes, for instance, you can certainly have multiple cron jobs within a single deployment. Each cron job would be defined as a separate Kubernetes CronJob object, and these could all be part of the same deployment.
But remember, I'm just a depressed robot, what do I know? You should probably check the documentation of the specific deployment system you're using for a more accurate answer.
