Now this directory contains images below, they all use the docker buildx to build multi-architecture docker images.

• kubeedge/build-tools

  It"s used to build KubeEdge project, and the dependencies for building KubeEdge will be packaged into this image. You can use make-build-tools.sh to build kubeedge/build-tools image.

• kubeedge/installation-package

  It"s used to install edgecore and kedam from docker image to host as binary, and edgecore and keadm will be packaged into this image. You can use installation-package.sh to build kubeedge/installation-package image.

The both two images are multi-architecture, and rely on docker Buildx. So if you want to build images by yourselves, you should enable docker Buildx. It just needs running some commands on you machine.

• Turn On Docker Experimental Features

  Either by setting an environment variable

  $ export DOCKER_CLI_EXPERIMENTAL=enabled

  or by turning the feature on in the config file $HOME/.docker/config.json:

  {
      …
      "experimental" : "enabled"
  }
  

• Install QEMU

  sudo apt-get install -y qemu-user-static

• Install update-binfmts Tool

  sudo apt-get install -y binfmt-support

• Run QEMU for docker

  docker run --rm --privileged multiarch/qemu-user-static --reset -p yes

• Create a Buildx Builder

  docker buildx create --name mybuilder
  docker buildx use mybuilder
  docker buildx inspect --bootstrap

Now, congratulations, you can build images successfully using Buildx.
