Hello, I'm new to docker. and wanted to communicate two containers. so I used this approach instead of making a new compose file. Linking Containers.
but I'm not able to connect my MQTT node with a broker. I have not assigned global port 1883.
here is NR docker log.
P.S: other than this I have not done anything like making mosquitto.conf file or moving[cp] to container. I only done this as shown above link. Am i missing something?
