Port 80 already in use

[cocolitto]

Hi,

I'm using balena with an private TTS stack and gateway (basicstation) on an Raspberry 3. I would like to stay localy in my net . The TTS (stack) container is already using port 80. Now i would like to integrate your NodeRed container to handle the data receiving from the TTS.

Could you tell me an easy way to change the port of the Nodered to something different than 80?

here the error log from the node-red container:

node-red 22 Nov 18:02:05 - [warn] Flows file name not set. Generating name using hostname. node-red 22 Nov 18:02:05 - [info] Flows file : /data/node-red/user/flows_22a2dbd.json node-red 22 Nov 18:02:05 - [info] Creating new flow file node-red 22 Nov 18:02:05 - [error] Unable to listen on http://127.0.0.1:80/ node-red 22 Nov 18:02:05 - [error] Error: port in use

Looking at the docker-compose.yml, I think you could change the Node-RED HOST_PORT 80 port (see ports):

node-red:
    image: bh.cr/balenablocks/balena-node-red
    container_name: node-red
    privileged: true
    restart: unless-stopped
    volumes:
        - 'node-red-data:/data'
    labels:
        io.balena.features.dbus: '1'
        io.balena.features.sysfs: '1'
        io.balena.features.supervisor-api: '1'
        io.balena.features.balena-api: '1'
    ports:
        - 80:80
    environment:
        PORT: 80
        USERNAME: "balena"
        PASSWORD: "balena"
        ENCRIPTION_KEY: "balena"        
    cap_add:
        - SYS_RAWIO
    devices:
        - "/dev/mem:/dev/mem"
        - "/dev/gpiomem:/dev/gpiomem"
        - "/dev/i2c-1:/dev/i2c-1"

Exactly @cocolitto did you try to change ports to - 8888:80?

On the other hand if you would like to use The Things Stack with MING, my recommendation is to use this repository https://github.com/xoseperez/standalone-lorawan-gateway-balena

Let me know if this works!
