+type: reference
+---
+
+PlateRunner is deployed on VM 103 (192.168.86.122, Proxmox2) at `/opt/docker/stacks/platerunner/`.
+
+- **Repo**: https://github.com/csader/platerunner.git (cloned on server)
+- **Container**: `platerunner-platecycler-1`, port mapping `3001:3000`
+- **Compose**: builds from source (multi-stage Dockerfile, Next.js standalone)
+- **Public URL**: platerunner.chrissader.com (Cloudflare Tunnel -> Caddy .134 -> .122:3001)
+- **Update process**: `git pull origin main` then `sudo docker compose up --build -d`
+- **Note**: `/opt/docker/stacks/` is owned by csader but Docker commands need sudo. Watch for root-owned .git files if sudo git operations are run accidentally.
+
+**How to apply:** When updating PlateRunner, SSH to .122 (not .134), pull the repo, and rebuild with docker compose.
