Description

The following configuration results in a tcp socket error for mqtt.

find3server:
  container_name: find3server
  restart: unless-stopped
  image: schollz/find3
  environment:
    - MQTT_ADMIN=admin
    - MQTT_PASS=mypass
    - MQTT_SERVER='localhost:1883'
  volumes:
    - /home/USER/find3server:/data
  ports:
    - "11883:1883"
    - "8003:8003"

I have no idea why. It should work. I think its a docker-compose error because regular Docker works just fine, e.g.:

docker run -p 1884:1883 -p 8005:8003 \
	-v /home/$USER/FIND_DATA:/data \
    -e MQTT_ADMIN=ADMIN \
    -e MQTT_PASS=PASSWORD \
    -e MQTT_SERVER='localhost:1883' \
	-e MQTT_EXTERNAL='your public IP' \
	-e MQTT_PORT=1884 \
	--name find3server -d -t schollz/find3

will work no problem.

Contributor guide

Research direction
Investigate why Docker Compose fails to connect to MQTT while plain Docker works. Compare the network setup, environment variable quoting, and port mapping in the compose file.
