WireGuard on Docker

[Mohammad Amir Heshmatkhah]

Hi,
I want to run WireGuard on a docker container as server,
I try difrent base Images but  I get this error message every time:

[#] ip link add wg0 type wireguard
RTNETLINK answers: Operation not supported
Unable to access interface: Protocol not supported
[#] ip link delete dev wg0
Cannot find device "wg0"

Here is 3 Dokerfiles I tried:

FROM alpine:3.7
RUN apk upgrade --update \
&& echo http://dl-cdn.alpinelinux.org/alpine/edge/testing >>
/etc/apk/repositories \
&& apk add --no-cache bash wireguard-tools

ENTRYPOINT [ "wg-quick", "up", "wg0" ]

————————————-

FROM ubuntu:16.04
RUN apt-get update && apt-get install -y software-properties-common
apt-utils \
&& add-apt-repository ppa:wireguard/wireguard \
&& apt-get update \
&& apt-get install -y iproute linux-headers-$(uname -r) wireguard-dkms
wireguard-tools wireguard

ENTRYPOINT [ "wg-quick", "up", "wg0" ]

————————————-

FROM debian:9
RUN echo "deb http://deb.debian.org/debian/ unstable main" >
/etc/apt/sources.list.d/unstable.list \
&& printf 'Package: *\nPin: release a=unstable\nPin-Priority: 150\n' >
/etc/apt/preferences.d/limit-unstable \
&& apt-get update && apt-get install -y wireguard

ENTRYPOINT [ "wg-quick", "up", "wg0" ]

————————————-

I run this containers with:

sudo docker run -it -v $(pwd)/config:/etc/wireguard/ -v  /dev:/dev  -v
/lib/modules:/lib/modules  --cap-add=ALL --privileged <image name here>

where wg0.conf is located in " $(pwd)/config/wg0.conf" on host machine

————————————-

and here is my wg0.conf file:

[Interface]
Address = 172.26.10.1/24
SaveConfig = true
PrivateKey = <server private key here>
ListenPort = 40540

[Peer]
PublicKey = <client public key here>
AllowedIPs = 172.26.10.2/32

————————————-

So, How can I fix this "*Unable to access interface: Protocol not supported*"
error?
