Persistent Volumes

Keep data across deployments with mounted Docker volumes.

Containers are ephemeral: each new deployment replaces the old container, and anything written to its local filesystem disappears with it. Mount a persistent volume for uploads, caches, SQLite files, or any data that must survive redeploys.

Adding a volume

Open the project and switch to the Volumes tab, then click Add Volume:

1. Enter the mount path inside the container (for example /app/uploads).
2. Save. Dequel creates a Docker volume on the deployment’s server and records the mount.

Mount changes apply on the next container start. The tab shows a redeploy banner after you add or delete a volume — click Redeploy to roll it out. Deleting a volume unmounts it; the volume record can be removed separately.

Databases vs volumes

• Use a managed database for structured data with querying, credentials, backups, and remote access.
• Use a volume for flat files your app reads and writes directly.

Next steps

• Read Managed Databases for the database option.
• Read Backups for snapshot and restore flows.
