Confirm data stays persistent - Docker Compose

[Anqui3tas]

Hi all,
I’m running Weblate 5.14.3 on a Synology NAS using Docker Compose. Everything builds and runs fine — Weblate starts, connects to Postgres, and I can access the web UI through a Cloudflare Tunnel.

However before getting too far, I tried making sure that data persists to the local storage, (as I frequently rebuild my container and setup) and don't want to lose data each time. I notice that changing information, such as Admin users full name to something else, saves fine, but after bringing the containers down and back up, it reverts back to "admin" and my change did not persist.

here is my (redacted) compose, I'm not extremely confident in my abilities, so mind any errors.

The below was how I got it working properly via cloudflare tunnel.

weblate:
        image: weblate/weblate:latest
        container_name: weblate
        ports:
            - 80:8080

            - /volume3/docker/weblate/Localizations:/app/data/repos/xcode
        environment:

            WEBLATE_ENABLE_PROXY_PROTO: "true"
            WEBLATE_SECURE_PROXY_SSL_HEADER: "HTTP_X_FORWARDED_PROTO,https"

            # Required database configuration

    weblate-db:

        environment:
            POSTGRES_USER: weblate
            POSTGRES_PASSWORD: #####
            POSTGRES_DB: weblate
        volumes:
            - /volume3/docker/weblate/postgres:/var/lib/postgresql/data
        restart: unless-stopped

    weblate-redis:
        image: redis:alpine
        container_name: weblate-redis
        restart: unless-stopped

This is described in the documentation: https://docs.weblate.org/en/latest/admin/install/docker.html#docker-container-volumes

I had reviewed that. My issue stemmed from testing this with the admin full name, which isn't persistent (unless added to the compose)

my setup is persistent, just not that item I was testing with.
