Configuring docker volume backups via docker labels

[tenekev]

Is your feature request related to a problem? Please describe.
It's nice that there is support for docker volumes now but since agents need docker socket access for this, we are a step away from being able to configure the agent with docker labels.

This way the whole config for the container lives with the compose file for it. And services like Traefik, Flame, etc., generate the config based on its labels.

Describe the solution you'd like
Instead of a JSON config file, I'd like to be able to define the settings as docker labels for a container.

Hi,

Thanks for the suggestion. It looks really interesting. Could you explain in more detail how you envision this use case?

Would you also be interested in contributing to this feature?

I'm not a professional so I might not be the best person to implement such a feature.

Here is an example of what I'm talking about. Flame is a dashboard service that runs as a docker container, watches for container that have labels containing flame config and populates the dashboard page with them:

services:
  hello-world:
    container_name: hello-world
    image: "hello-world"
    networks:
      - proxy
    ......
    labels:
      - flame.type=application # "app" works too
      - flame.name=My container
      - flame.url=https://example.com
      - flame.icon=icon-name # optional, default is "docker"

The most popular example is Traefik with its label config. Instead of a file, you can define everything about a service in the labels.

services:
  flame:
    image: ghcr.io/fdarveau/flame:latest
    container_name: flame
    environment:
      - PASSWORD=pass
    networks:
      - proxy
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.flame.entrypoints=http"
      - "traefik.http.routers.flame.rule=Host(`${DOMAIN_NAME}`)"
      - "traefik.http.routers.flame.middlewares=https-redirect@file"
      - "traefik.http.routers.flame-secure.entrypoints=https"
      - "traefik.http.routers.flame-secure.rule=Host(`${DOMAIN_NAME}`)"
      - "traefik.http.routers.flame-secure.tls=true"
      - "traefik.http.routers.flame-secure.service=flame"
      - "traefik.http.services.flame.loadbalancer.server.port=5005"
      - "traefik.docker.network=proxy"

After going through the portabase config file, I imagine it can go very cleanly in docker labels like so:

services:
  flame:
    image: ghcr.io/fdarveau/flame:latest
      - flame-data:/app
    labels:
      - "portabase.enable=true"
      - "portabase.name=Flame - Docker Volume"
      - "portabase.type=docker-volume"
      - "portabase.volume_name=flame_flame-data"
      - "portabase.generated_id=16706126-ff7e-4c97-8c83-0adeff214690"
      - "portabase.container_name=flame"

This way we can define everything about a service in one place and let management services piece together the config.

Thank you for all that information. We will look into it more closely and see what we can do.
