image on synology "RTNETLINK answers: Not supported"

[cscholz]

I've deployed the alpine image as described and get the following log errors. I've tried it with a shared host docker network and also with a non host shared network. Do you have a hint for me?

I have a couple of possible things:
I'm guessing the device is some other architecture (maybe arm?) and the images here have only been built for amd64. They should build fine for other architectures (minus the kernel installation piece) since it is only bash scripts, but you would need to build an image specifically for that platform.

I think the first RNETLINK answers: Not supported may mean that the device's kernel doesn't have wireguard included or a wireguard module. You would have to do more research on that to see if synology has an available kernel or kernel module for wireguard
