ofelia in docker-mode did not allow job-run on non-ofelia containers, is this correct?

[jk]

I've modified the example from the readme to run a seperate container from the nginx service, like so:

version: "3.8"

services:
  ofelia:
    image: mcuadros/ofelia:latest
    depends_on:
      - nginx
    command: daemon --docker
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro

  nginx:
    image: nginx:latest
    labels:
      ofelia.enabled: "true"
      ofelia.job-run.ofelia-test.schedule: "@every 5s"
      ofelia.job-run.ofelia-test.image: "alpine:latest"
      ofelia.job-run.ofelia-test.command: "date"

But ofelia doesn't seem to find the job-run labels:

ofelia-test-ofelia-1  | unable to start a empty scheduler.
ofelia-test-ofelia-1 exited with code 1

IMO I expect ofelia to pick up the labels annotated in the nginx service, but no. When moving these exact same labels to the ofeila service, it works:

version: "3.8"

services:
  ofelia:
    image: mcuadros/ofelia:latest
    depends_on:
      - nginx
    command: daemon --docker
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
    labels:
      ofelia.enabled: "true"
      ofelia.job-run.ofelia-test.schedule: "@every 5s"
      ofelia.job-run.ofelia-test.image: "alpine:latest"
      ofelia.job-run.ofelia-test.command: "date"

  nginx:
    image: nginx:latest

and I get the following error on starting up ofelia:

ofelia-test-ofelia-1  | 2021-11-29T15:51:30.797Z  scheduler.go:34 ▶ NOTICE New job registered "ofelia-test" - "date" - "@every 5s"

Looks like ofelia isn't able start seperate containers for non-ofeila images. According to https://github.com/mcuadros/ofelia/blob/master/docs/jobs.md#job-run this is nowhere stated, is this a bug or the intended behavior?

Remove the --docker parameter.

My problem looks similar see #270 (I'm not using this --docker parameter) Documentation about how to use job-run with labels should probably be improved. I will do (if I understand what is wrong with my settings)
