I am storing certain .json and it is scheduled to be stored once in a day when load is less. But every new commit in GitHub will trigger auto-build process. I want that, .json stored shall be accessible to all deployments rather than being deleted in each build process. Is there any way to achieve on this platform. I am on hobby plan.
I am newbie on railway, so please help me out!!
Thanks!!

What you need is called volumes. They are persistent data storage that keep state between deployments.
What currently is happening is your app creates a file at /app/data.json. When a new deployment comes, a new container is spun up and previous container along with any data is deleted.
If you want to persist the data.json file then you need to mount the volume at /app so that when a new container is spun up, the same volume is mounted that contains any data written at /app location by previous containers.

Can you please elaborate? What type of data from deployment 1 you need for deployment 2 that you're not getting?
I mean, you can always push the JSON to a database (PostgreSQL, Redis) or a service like S3, Cloudflare R2, Supabase Storage, etc.
