Updated and polished Dockerfile

[daFritz84]

I gave some love to the existing Dockerfile:

• updated base image from 10.15.3 to latest node image
• switched from Debian based image to Alpine image (size goes down from over 900 MiB to ~180 MiB)
• fixed wrong volume mapping (local.json should not be a directory), rather config/default.json should be adapted
• exposed also port 3001 for logging

I also added a docker_build shell script. Not really necessary, but it saves precious typing time.

Tried and tested on my local Intel NUC.

Works fine. I build a custom docker-image based on that with MultiArch-Support for ARM32/ARM64

thanks @daFritz84

did some more modifications. hope I didn't mess it up. How do you run it??? I can't find the broadlink device when scanning.

/config = if you using a local.json config file /commands = where to place the commands

docker run --rm -it -v /Users/backer/Work/broadlink-mqtt-bridge/commands:/commands -v /Users/backer/Work/broadlink-mqtt-bridge/test:/config -p 3000:3000/tcp -p 3001:3001/tcp fredrickbacker/broadlink-mqtt-bridge:latest

I created a macvlan-bridge an use a dedicated IP for the mqttbridge. Then autodiscovery is working fine.

Hi,

try adding the --net=host to your command.

I run into the same problem when first trying out your service with docker and scratched my head for a bit. Until I realized that the local IP is used to determine the IP scan range and docker, of course, creates a software defined network separated from the host for its containers. So if you want the IP address of the docker host (i.e., the machine you are running docker on) to be visible to your container you have to enable 'host mode'.

Btw., here is a snippet from my docker-compose file as reference:

  broadlink2mqtt:
    container_name: broadlink2mqtt
    image: broadlink-mqtt-bridge:latest
    restart: unless-stopped
    volumes:
      - /opt/broadlink2mqtt/config:/broadlink-mqtt-bridge/config
      - /opt/broadlink2mqtt/commands:/broadlink-mqtt-bridge/commands
    network_mode: "host"
    ports:
      - 3000:3000
      - 3001:3001

tried running host docker run --rm -it -v /Users/backer/Work/broadlink-mqtt-bridge/commands:/commands --net=host fredrickbacker/broadlink-mqtt-bridge:latestbut then I can't access localhost:3000. Remember I've some issues with this before but don't know how I sovled it. only using host would be easiest solution than adding special networking

[daFritz84]

localhost won't work, since docker does not bind to 127.0.0.1 on the host machine (as far as I remember). Try the external ip of the host machine, e.g. http://192.168.194.46:3000/

Cheers, loaded up on the ubuntu in the basement, running and finding. Will update the docs. Thanks for the help.
