## Deploying your own SyncServer to Railway

Setup a service and attach a volume under `/data` to it.

Since cache-mounts on Railway need to prefixed with the service ID and BuildKit doesn’t expand variables there. You must give it a literal value for the mount ID.

To do so you can fill in the service ID below and run the command before your `railway up` command.
More info here: https://docs.railway.com/guides/dockerfiles#cache-mounts
Get the service ID by using CMD/CTRL+K and search for `Copy Service ID`.

```sh
sed -i '' \
's|\(--mount=type=cache,id=\)workspace|\1s/<service-id>-pnpm-store|' \
Dockerfile
railway up
```

Note: By default horizontal scaling is disabled because of the attached volume.
