toolchain

This repository produces a fully bootstrapped (using [Stageˣ]) base toolchain with the following components:

• busybox shell
• binutils
• GCC
• Linux headers
• musl libc
• GNU Make
• Go

Currently, a fork of [Stageˣ] is used to provide multiplatform support.

This toolchain should be capable of building all parts of Talos Linux without relying on tools other than image build tools.

Development

The development of this toolchain depends on Docker 19.03.0 or greater and bldr. The toolchain can be built for different architectures (e.g. x86_64, aarch64, etc.). To do this you will need to setup the proper docker context for the architecture you intend on building for. For example, to setup the build for aarch64 (arm64):

docker context create arm64 \
    --description "An arm64 builder" \
    --docker "host=tcp://$IP:2376,ca=${HOME}/.docker/client/ca.pem,cert=${HOME}/.docker/client/cert.pem,key=${HOME}/.docker/client/key.pem"
docker buildx create \
    --use \
    --name arm64-builder \
    arm64

Note: You can run the above steps against an x86_64 machine, substituting arm64 with amd64.

Then, to build:

make USERNAME=${DOCKER_HUB_USERNAME} PLATFORM=linux/arm64 PUSH=true

Note: You can use PLATFORM=linux/amd64,linux/arm64 if you have configured docker with and amd64 and arm64 contexts.
