Installation

Docker buildkit is required for multi-arch builds. Unless integrated in docker already, install it:

mkdir -p ~/.docker/cli-plugins
wget https://github.com/docker/buildx/releases/download/${version}/buildx-v{version}.linux-$arch -O ~/.docker/cli-plugins/docker-buildx
chmod a+x ~/.docker/cli-plugins/docker-buildx
docker buildx create --use
