OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

Sunshine!

Stock OpenWrt firmware; only the LuCI WebUI has been added, with no other modifications.

Instructions for Use

Create a macvlan network

Execute the following command in the Armbian host terminal to bridge OpenWrt to your physical network interface (assuming your host interface is eth0 and the main router's subnet is 192.168.1.x):

docker network create -d macvlan \
  --subnet=192.168.1.0/24 \
  --gateway=192.168.1.1 \
  -o parent=eth0 openwrt_macvlan

Docker run

docker run -d \
  --name openwrt \
  --restart always \
  --network openwrt_macvlan \
  --privileged \
  -v /lib/modules:/lib/modules:ro \
  -v /etc/localtime:/etc/localtime:ro \
  -v openwrt_overlay:/overlay \
