docker-buildkit - 如何推送到 localhost:500 注册表：2 - 连接：连接被拒绝

Question

创建本地注册表：

reg_name='kind-registry'
reg_port='5000'
running="$(docker inspect -f '{{.State.Running}}' "${reg_name}" 2>/dev/null || true)"
if [ "${running}" != 'true' ]; then
  docker run \
    -d --restart=always -p "127.0.0.1:${reg_port}:5000" --name "${reg_name}" \
    registry:2
fi

创建了一个构建器：

docker buildx create --name my-builder --platform linux/arm64

docker buildx build --builder my-builder --tag localhost:5000/micro --platform linux/arm64 --push -f ./docker/Dockerfile . 

错误：
