Disks

Attach persistent storage to your services. Data survives redeploys and container restarts. Useful for file uploads, SQLite databases, or any stateful data.

railpush.yaml

services:
  - type: web
    name: my-app
    runtime: node
    disk:
      name: uploads
      mountPath: /var/data/uploads
      sizeGB: 25

Single-instance only

Persistent disks can only be attached to services with a single instance. You cannot use disks with auto-scaled services.
