Openwrt in Docker

Principle of this solution:

Use the macvlan network of docker to virtualize a layer 2 network card, as the physical network card of the container

Docker Firmware Username/Password： root/password

Firmware Link: raymondwong/openwrt_r9

IMPORTANT! Make sure your local network is on 192.168.1.0/24 subnet

Option 1: Shell Command

ip link set [your network card, such as eth0] promisc on 
docker network create -d macvlan --subnet=192.168.1.0/24 --gateway=192.168.1.1 -o parent=[your network card] macnet
docker run --restart always -d --network macnet --privileged -v /lib/modules:/lib/modules raymondwong/openwrt_r9:autobuild-22.2.12-arm64

PS: Switch to autobuild-22.2.12-x86_64 if running on X86 machine.
Open http://192.168.1.254, test whether the deployment was successful

Option 2: (Docker Compse):

ip link set [your network card, such as eth0] promisc on 
mkdir openwrt&&cd openwrt 
# copy below code to 'docker-compose.yaml', and modify `driver_opts: parent` value to your nic
docker-compose up -d

PS: Switch to autobuild-22.2.12-x86_64 if running on X86 machine.
Open http://192.168.1.254, test whether the deployment was successful

docker-compose.yaml：

version: '2'
services:
  openwrt:
    image: raymondwong/openwrt_r9:autobuild-22.2.12-arm64
    container_name: openwrt_r9
    privileged: true
    restart: always
    networks:
      openwrt_macnet:
        ipv4_address: 192.168.1.254

networks:
  openwrt_macnet:
    driver: macvlan
    driver_opts:
      parent: en0
    ipam:
      config:
        - subnet: 192.168.1.0/24
          ip_range: 192.168.1.128/25
          gateway: 192.168.1.1

PS：This tutorial solution is a single virtual network card solution. If some plug-ins are not working properly, you can try to add 2 virtual network cards to simulate real routing
