一、docker build一个新image
Note: 设置root密码:root; 创建bsp组，bsp用户；宿主机的bsp用户gid是1001， uid也是1001；docker 容器创建与宿主机相同用户，可以保证宿主机与容器对文件的所属组，用户属性保持一致；
参考链接：理解 docker 容器中的 uid 和 gid
1.1 下载ubuntu16.04 image
docker pull ubuntu:16.04
1.2 编写Dockerfile
# base image
FROM ubuntu:16.04
# MAINTAINER
MAINTAINER user@xxx.com
# 配置时区
RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
# modify root passwd
RUN echo "root:root" | chpasswd
# add user,group
RUN groupadd -g 1001 bsp
RUN useradd -m -u 1001 -g 1001 bsp
USER bsp
#RUN mkdir -p /home/bsp/work
#RUN chown bsp:bsp /home/bsp/work
# change dir to /home/bsp/work
WORKDIR /home/bsp
1.3 生成新的imags
docker build -t ubuntu16.04_bsp:v1.4 .
二、进入新image容器，安装android编译环境
2.1 启动新image的容器
docker run -it -v /home/bsp/work:/home/bsp/work --name ubuntu16.04_bsp ubuntu16.04_bsp:v1.4 /bin/bash
2.2 搭建android编译环境（Note:此小节均在docker容器内操作）
2.2.1 更新容器source源
su root #pw:root
# 更换source.list
mv /etc/apt/source.list /etc/apt/source.list.bak
# 使用某用户user源，可选操作
scp -r user@10.235.112.135:/etc/apt/source.list /etc/apt/source.list
apt-get install vim
# source.list增加阿里云源

apt-get update
2.2.2 安装android编译所需工具
所需工具参考高通user guide文档描述
#Android build env
apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev libc6-dev lib32ncurses5-dev libx11-dev lib32z-dev libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc

#lib32readline5-dev
apt-get install lib32readline-gplv2-dev
#uuid-dev
apt-get install libuuid1=2.27.1-6ubuntu3
apt-get install uuid-dev
apt-get install xmlstarlet
# libxml-simple-perl
apt-get install libxml-simple-perl
# libssl-dev
apt-get install libssl-dev
# libswitch-perl
apt-get install libswitch-perl
# cpio
apt-get install cpio
# change bash
rm /bin/sh
ln -s /bin/bash /bin/sh
# /etc/passwd bsp用户默认shell增加/bin/bash
# bsp:x:1001:1001::/home/bsp:
bsp:x:1001:1001::/home/bsp:/bin/bash
# 安装JDK
apt-get install openjdk-8-jdk
java --version
2.2.3 安装其他工具
# 安装repo
# repo安装链接 [https://source.android.com/source/downloading](https://source.android.com/source/downloading)
su bsp
mkdir ~/bin
PATH=~/bin:$PATH #添加到bsp的.bashrc
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
su root
# 安装python3.6
apt-get install software-properties-common
add-apt-repository ppa:deadsnakes/ppa
apt-get update
apt-get install python3.6
su bsp
# bsp用户.bashrc添加
alias python='/usr/bin/python3.6'
# 自动补全
apt-get install bash-completion
# ifconfig工具
apt-get install net-tools
# ping
apt-get install inetutils-ping
# tree
apt-get install inetutils-ping
# sudo
apt-get install sudo
# 增加bsp sudo使用权限
echo "bsp ALL=(ALL:ALL) ALL" >> /etc/sudoers
passwd bsp #设置bsp密码:bsp
三、保存为新的docker images
docker容器中android编译需要的工具，以及一些其他常用工具安装完成后；测试可以全编译通过sm8350源码；说明此时docker容器的环境已满足android build需求；将此时容器的状态commit，保存为一个新的docker image；后续可直接使用该image启动容器，直接进入挂载的源码路径编译android；
3.1 commit新的image
# 宿主机执行，cfd56a81cb97 为上述2.2小节运行中的容器ID
docker commit cfd56a81cb97 ubuntu16.04_bsp:v1.5
3.2 启动android-build 容器
docker images #查看v1.8的images，示例
#bsp@cv-ThinkStation-P620:~$ docker images
#REPOSITORY TAG IMAGE ID CREATED SIZE
#ubuntu16.04_bsp v1.8 e66ac7525780 7 seconds ago 1.29GB
#ubuntu16.04_bsp v1.7 73de1074c60e 14 hours ago 1.29GB
#ubuntu16.04_bsp v1.6 4fe2b3a64515 14 hours ago 1.29GB
docker run -it -v /home/bsp/work:/home/bsp/work -p 10022:22 --name android-build ubuntu16.04_bsp:v1.8 /bin/bash
# -v : 挂载宿主机/home/bsp/work到容器/home/bsp/work路径
# -p : 将宿主机10022端口映射到容器22端口（启动多个容器，注意避免端口冲突）；这样可直接使用ssh -p 10022 bsp@10.235.112.193 登录到容器
# --name : 容器命名为android-build；用户可自行命名一个容器，后续使用自己的容器可做到互不干扰。
docker容器 root密码：root
docker容器 bsp密码：bsp
