How to get my rtl_433.conf into a container

[HolgerAusB]

I am using rtl_433 for some years now by using the 'building' option. But I am not very good in coding and building things. So I never updated this installation. But it works.

Now I want to use a new Raspberry Pi 4 for all of my Smart Home things and also move the rtl-stick to this. I want to give the docker version a try and using the docker-compose.yml option. But I want to reuse my rtl_433.conf which contains two flex devices (-X) for my doorbells.

Would it be enough to set the following to the docker-compose.yml file?:

volumes:
      - ./data:/etc/rtl_433

and removing the command section?

Looking at the -h output of the process you will see the following message that can be a good hint to what to try

A "rtl_433.conf" file is searched in "./", XDG_CONFIG_HOME e.g. "$HOME/.config/rtl_433/",
  SYSCONFDIR e.g. "/usr/local/etc/rtl_433/", then command line args will be parsed in order.

There's also [-c <path>] Read config options from a file if all previous fails you can put the file anywhere in the container (volume mount would do fine) and use the -c /path/to/that/file.conf if all else fails.
