Using the PostgreSQL backend

Now supports PostgreSQL backend.

Because upstream Rclone image is based on alpine 3.16(and linux/arm/v6 platform is based on alpine 3.15), it only supports PostgreSQL 14 and previous versions, see Alpine 3.16 Packages and Alpine 3.15 Packages.

We support PostgreSQL 15 and previous versions.


Environment Variables

DB_TYPE

Set to postgresql switch to PostgreSQL database.

Default: sqlite

PG_HOST

PostgreSQL host, required.

PG_PORT

PostgreSQL port.

Default: 5432

PG_DBNAME

PostgreSQL database name.

Default: vaultwarden

PG_USERNAME

PostgreSQL username.

Default: vaultwarden

PG_PASSWORD

PostgreSQL password, required.

The login information will be saved in the ~/.pgpass file.


Backup

Specify the above environment variables to switch to the PostgreSQL database.


Restore

When restoring, also specify the above environment variables to switch to the PostgreSQL database.

  1. Ensure that the database is accessible.

Perhaps you will use the docker-compose up -d [services name] command to start the database separately.

  1. Verify that the PG_HOST you are using is accessible to.

If your database is running in docker-compose, you need to find the corresponding network name via docker network ls and add --network=[name] to the restore command to specify the network name.

  1. Restore and restart the container.
