openwrt-builder

A docker container to build openwrt images from the buildroot.

Following the steps described in OpenWRT wiki: https://openwrt.org/docs/guide-developer/quickstart-build-images

How to build an image

Jump into a new folder and run your buildroot shell

docker run -it -v $(pwd):/home/builder/openwrt/bin/ openwrt-builder bash

From that point, just run make menuconfig in order to customize your build then make -j1 to build the images.

The compiled images will be placed in the newly created ./targets folder in your current working directory.

How to embed files

Create a files directory. Everything inside this directory will be placed at / in the image.

Inside this directory, place your custom openwrt files. For example your would create a files/etc/config/wireless file in order to change the default wireless configuration.

Then, when running the container, specify the location for this directory. (Let's say its in the $FILES variable).

docker run -it -v $(pwd):/home/builder/openwrt/bin/ -v ${FILES}:/home/builder/openwrt/files openwrt-builder bash
