I created a cluster on GKE with Container-Optimized OS and when trying to create a wireguard interface inside a Pod, I get the error message

```
# wg-quick up wg0
[#] ip link add wg0 type wireguard
RTNETLINK answers: Not supported

```

Typically, this means that the wireguard kernel module is not installed. On a Linux machine, you would install wireguard-dkms and run ‘modprobe wireguard’ to resolve this issue.

Does CO-OS support wireguard? SHould I choose a different kernel for my cluster’s nodes to be able to create wireguard interfaces inside the Pods?
