Hello,

I'm trying to set up a development environment with docker since I need a virtual canbus (vcan) device under windows.  
I am using the latest docker image `nodered/node-red:latest` following the guide under documentation.

The plan is to use the "node-red-contrib-can" module but I would need to set up a virtual can interface.  
I know the node-red docker is alpine linux based and I managed to install can-utils.  
But I think the can module/kernel options are turned off.

When I run `/usr/src/node-red # modprobe vcan`  
the result is  
`modprobe: FATAL: Module vcan not found in directory /lib/modules/5.15.146.1-microsoft-standard-WSL2`

Would I need to build my own [custom docker image](https://nodered.org/docs/getting-started/docker-custom) (I did find some guide)?  
Or is it something simple I am missing?

Note: I do not have an actual can device attached. I just need a virtual one in a docker container.
