Can't create container with portainer stack

[BMWK1]

Hi, promising piece of software ! but i a m stuck with the docker installation because of the compose stack, particulary the volumes entry:

As you will notice, i am not a so familiar with Docker and compose, so sorry for newbies question

i want to install rfxcom2mqtt in a docker container on my synology NAS: -the installation path i want to use is: volume1/docker/rfxcom2mqtt

• i have understood that we need a data folder, but i don't know how to write the correct "volumes" line i tried several syntaxes, but always got error messages: /data/compose/40/data' does not exists, which increases each time i try ( 41,42,43) So it looks that the installation wants to create some new folders like "compose/40", but my synology seems to refuse ( not root rights ?)

Here is my last try of the docker compose, i have manually created the folder volume1/docker/rdx2mqtt/app/data

`version: '3.8' services: rfxcom2mqtt: container_name: rfxcom2mqtt image: rfxcom2mqtt/rfxcom2mqtt restart: unless-stopped volumes:

• ./data:volume1/docker/rfx2mqtt/app/data environment:
• TZ=Europe/Paris devices:

  Make sure this matched your adapter location

• /dev/ttyUSB0 # on a synology nas, i can't use the "by-id" feature

So could you give all the folders to be created, ande the corresponding "volumes" entries in the Docker compose stack ?

Hello, we need to start with path in your nas /volume1/docker/rfx2mqtt/

volumes:
  - /volume1/docker/rfx2mqtt/:/app/data
