Buildroot Docker images

This repository contains Docker images for buildroot.

How to use

This buildroot image should be used according to the buildroot documentation about "Keeping customizations outside of Buildroot".

Create a directory containing your buildroot customizations, for example:

+-- board/
|   +-- <company>/
|       +-- <boardname>/
|           +-- linux.config
|
+-- configs/
|   +-- <boardname>_defconfig
|
+-- package/
|   +-- <company>/
|       +-- package1/
|       |    +-- Config.in
|       |    +-- package1.mk
|       +-- package2/
|           +-- Config.in
|           +-- package2.mk
|
+-- Config.in
+-- external.desc
+-- external.mk

To use your configuration with the buildroot image use a volume mount to mount the directory inside the container and set the BR2_EXTERNAL environment variable to the directory name inside the container. For example:

docker run -ti -e BR2_EXTERNAL=/mycustombuildroot -v `pwd`:/mycustombuildroot simonvanderveldt/buildroot:2021.02.3

Now you can issue your regular buildroot commands, like make menuconfig or make <boardname>_defconfig followed by make.
