I have a container that I'd like to use for my API server and as a periodic cron task.
1. How can that container know whether it is being invoked as a cron job or as the API server?
2. Is there an environment variable set?
3. Is there an environment override I can add to railway.json specifically for cron jobs?
4. Is there a way to override the command that is run for cron jobs, as there is with preDeployCommand?
I do not see anything described on https://docs.railway.com/reference/variables#railway-provided-variables that would be applicable.

Hi there,
We currently don't support this — could you create a separate service for the cron part of the current service?
The service is expected to execute a task, and exit as soon as that task is finished, not leaving any resources open, such as database connections. More on execution requirements below.

Yes, we can. Is it possible to define the cron-related settings in the railway.json Config-as-Code file, or does it have to be configured through the UI? I don't see this in the docs.

Yes you can do that with config as code: https://docs.railway.com/reference/config-as-code#cron-schedule
Most if not all settings configurable by UI can be defined as code.
