Hi,
Trying to access serial ports on a Raspberry Pi from node red in a docker container.
But the only thing that happens is that the docker container exits. Being a newbie when
it comes to docker, maybe I'm making some stupid mistakes. It works fine running node red directly
on the host RPi
This is what happens:
```auto
pi@raspberrypi:~ $ sudo docker run -it --rm --name NodeRed --device=/dev/ttyUSB0 -p 1881:1880 -v /home/pi/node-red-docker-storage/node-red:/data nodered/node-red
> node-red-docker@2.2.2 start /usr/src/node-red
> node $NODE_OPTIONS node_modules/node-red/red.js $FLOWS "--userDir" "/data"

Welcome to Node-RED

```
```
<- Added serial port node, configured for /dev/ttyUSB0 and deploy.
```
```auto
24 Oct 11:56:54 - [info] Stopping flows
24 Oct 11:56:54 - [info] Stopped flows
24 Oct 11:56:54 - [info] Starting flows
24 Oct 11:56:54 - [info] Started flows
pi@raspberrypi:~ $ <- Docker containter exits.
```
The only way to get into the container again is to start without --device.
Is this a node red or a docker question?
What I'm I doing wrong?

Very likely the same issue as this...

> I assume you realise the serial node uses C bindings and requires either the correct binaries or compilation on the guest? Does your image have the necessary tools installed to compile the serial port? See this issue: [serialport@10.3.0 fails in docker container on rpi · Issue #2438 · serialport/node-serialport · GitHub](https://github.com/serialport/node-serialport/issues/2438#issuecomment-1076374277) - might be relevant.
