Docker Containers for using Buildroot with the D1 Nezha

D1 Buildroot

NOTE: I'm currently not keeping a close eye on this repository and updating it for all new buildroot releases. If you would like a different buildroot release added to the system, please open an issue and I will add it

This repository contains the files necessary to create Docker containers that can then be used to build Linux Images for the D1 Nezha

Building the Containers is automated using GitHub actions. The containers are re-built automatically once a week, or whenever a push is made to the master branch.

Container Tags

Containers are built for each full release of Buildroot that supports the D1-Nezha. Pre-release and release candidates for Buildroot are not created. All containers are currently based on the ubuntu:20.04 container created by Docker. For each version of Buildroot, three containers are generated.

• base: Buildroot and dependencies installed, nezha_defconfig selected
• toolchain: Everying in the base image, plus the toolchain is pre-compiled by running make toolchain
• prebuilt: Everything in the toolchain image, plus a base Linux system is pre-compiled by running make.

Manually Building Containers

If you want to manually build a container, using docker build will create a container based on the newest version of Buildroot, with a Linux image pre-compiled.

Specifying Pre-Compilation

If you just want your container to have Buildroot and its dependencies installed and configured for the D1 Nezha, without pre-compiling the toolchain or a Linux image, set Docker's --target option to base, like so:

docker build --target base .

If you want the container to have a pre-built toolchain, but not a pre-built Linux image, set the --target option to toolchain, like so:

docker build --target toolchain .

Specifying Buildroot Version

To specify a custom Buildroot version, use pass BUILDROOT_VERSION as a build argument to Docker, and the specified version of buildroot will be downloaded during the build process. For example, to create a container based on Buildroot 2021.11-rc2, run the following command:

docker build --build BUILDROOT_VERSION=2021.11-rc2 .
