前言：
安装交叉编译环境，繁琐，耗时间，还得解决ubuntu版本不同，导致的各种错误。docker很好的解决了，不同版本，不同系统之间的差异性的问题。DOPI制作了docker方式的交叉编译环境。
工作环境：
vmare安装的ubuntu18.04
安装docker
sudo chmod 777 /etc/apt/sources.list
vi /etc/apt/sources.list
从源中选择对应版本的更新源：复制到 source.list 中。
sudo apt-get remove docker docker-engine docker.io containerd runc
sudo apt-get install -y curl
curl https://releases.rancher.com/install-docker/18.09.sh | sh
执行过程：
dopi@ubuntu:$ curl https://releases.rancher.com/install-docker/18.09.sh | sh

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:
sudo usermod -aG docker dopi
Remember that you will have to log out and back in for this to take effect!
WARNING: Adding a user to the "docker" group will grant the ability to run
containers which can be used to obtain root privileges on the
docker host.
Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
for more information.

创建Docker容器
假设您的git的uboot，linux，rootfs文件在/usr/dopi目录下，然后执行：
sudo docker run -it -v $PWD:/usr/dopi --name dopi_ev200 cijliu/arm-himix100-linux bash
这样，就进入到了Docker容器内，并且把当前路径挂载在容器的/usr/dopi路径，接下来开始编译。
