bse-docker container for build imx8mm-bse OS image

1. to install docker.io, please reference this article. And to add your account into docker group and launch docker

   sudo groupadd docker # for create docker group

   sudo usermod -aG docker <your account> # add your account into docker group

   sudo reboot # reminds: please reboot the host

2. clone this repository on your local development host

   git clone https://github.com/aaeon-kunyi/bse-docker.git

3. build the docker image

   cd bse-docker

   ./build_container.sh # the step will build a docker image on local host and create ./works folder for place your source code

   or pull image from github packages

   docker pull docker.pkg.github.com/aaeon-kunyi/bse-docker/bse-build-dev:latest

   docker tag docker.pkg.github.com/aaeon-kunyi/bse-docker/bse-build-dev bse-build-dev:1.0

4. put ** 'debian-bse_20201211.tgz' ** into ./works and decompress it

   tar zxvf debian-bse_20201211.tgz

   MACHINE=imx8mm-bse ./aaeon_make_debian.sh -c deploy

5. run the docker image for build imx8mm-bse OS root filesystem and bootloader

   ./run_container.sh # the step will start a container

   sudo MACHINE=imx8mm-bse ./aaeon_make_debian.sh -c all

6. due to docker container limitation, we need exit container environment firt then to generation image

   exit # for exit container

   cd works # into works folder

   sudo MACHINE=imx8mm-bse ./aaeon_make_debian.sh -c rescu

   cd ..

7. to check ./output folder

   ls ./output

   # will show the below on screen

   fw_printenv Image.gz imx8mm-bse.dtb imx8mm-bse_setup.img imx-boot-sd.bin rootfs.tar.gz
