[Help] pixolution/flow can’t write to mounted volume /var/solr on Railway (“Cannot write to /var/solr as 8983:8983”)

Question

**Summary**  
I’m deploying `pixolution/flow` on Railway. I attach a Volume at **/var/solr** (as recommended by Pixolution for persistence). The container starts but keeps logging:

`Cannot write to /var/solr as 8983:8983 drwxr-xr-x 3 root root 4096 Aug 5 05:18 /var/solr`

It looks like the app runs as user **UID/GID 8983** (Solr default), while the mounted volume path is owned by `root:root` with `755`, so the process can’t write.

### Environment

* **Image**: `pixolution/flow:latest`
* **Port**: 8983
* **Volume**: 50 GB, mount path `/var/solr`
* **Region**: Southeast Asia (Singapore)
* **Start Command**: default (no override)
* **Topology**: single service (Flow) + one persistent Volume
