Postgresql in docker-compose with secret key file

Help
1

Greetings!
I’m new to docker so far, so don’t judge harshly :slight_smile:
Such a question, I want to set up a connection with postgresql my vaultwarden image here is my compose file.

version: '3.8'

services:
  vaultwarden_db:
    container_name: Vaultwarden-DB
    hostname: vaultwarden-DB
    image: postgres:14
    environment:
     - POSTGRES_PASSWORD_FILE=/run/secrets/vw-postgresql.key
     - POSTGRES_DB=vaultwarden_DB
     - POSTGRES_USER=vaultwardenuser
    healthcheck:
      test: [“CMD”, “pg_isready”, “-q”, “-d”, “vaultwarden_DB”, “-U”, “vaultwardenuser”]
    networks:
      - dmz-proxy
    secrets:
     - vw-postgresql.key
    volumes:
     - volume_vault_vaultwarden:var/lib/postgresql/data:rw
  bitwarden_vaultwarden:
    container_name: bitwarden
    hostname: vaultwarden
    image: vaultwarden/server:latest
    restart: always
    environment:
         - DATABASE_URL=postgresql://vaultwardenuser:/run/secrets/vw-postgresql.key@Vaultwarden-DB:5432/vaultwarden_DB

Am I right in specifying the path to the secret key-file, or is it still not possible to pass the secret file as a password to the database?
