+# Docker Compose Bind Mount Preview Test
+
+Test case for [coolify#7802](https://github.com/coollabsio/coolify/issues/7802) — volume mappings from repo content in Preview Deployments.
+
+## Setup
+
+1. Add this repo as a Docker Compose resource in Coolify
+2. Set the base directory to `/docker-compose-bind-mount-preview`
+3. Deploy — should succeed (db_bootstrap runs the script from `./scripts`)
+4. Enable **Preview Deployments**
+5. Open a PR and deploy the preview
+
+## Expected
+
+The preview deployment should work the same as the main deployment — the `./scripts` bind mount should resolve to the repo's `scripts/` directory.
+
+## Actual (bug)
+
+The preview deployment fails because Coolify appends `-pr-N` to the bind mount path, looking for `scripts-pr-1` which doesn't exist.
