mapping config

[Seb788]

Hi,
im trying to map the config file to /app/config.json in docker.
it doesn't work for me.
i always get " invalid configuration file...using default configuration.

I use this command.
docker container run -it --rm p 3000:3000 -v $PWD/config.json:app mapclient

Could you write an example for the proper way to map this file?
Thank you

This is how my docker-compose file looks like

    icantbelieveitsnotvaletudo:
        build:
          context: ./ICantBelieveItsNotValetudo/
          dockerfile: Dockerfile
        container_name: "ICantBelieveItsNotValetudo"
        restart: always
        volumes:
            - /opt/dockerized/ICantBelieveItsNotValetudo/config.json:/app/config.json

Hi Hypfer,
It is still not working,

I created a file on the host named config.json with my mqtt info in it.
/root/Documents/mapclient/IcantBelieveItsNotValetudo/config.json

then I created a simple docker file like this

`    icantbelieveitsnotvaletudo:
        build: .
        container_name: "ICantBelieveItsNotValetudo"
        volumes:
            - /root/Documents/mapclient/IcantBelieveItsNotValetudo/config.json:/app/config.json`

The image gets build and the container starts
but I always get this error,

`root@debian-ha:~/Documents/mapclient/ICantBelieveItsNotValetudo# docker-compose up

Thanks for your help.

/root/Documents/mapclient/IcantBelieveItsNotValetudo/config.json is most likely a directory
