1准备一个linux环境

物理机器或虚拟机中安装linux系统都行

2安装docker

这个可以搜索教程自己装

3构建Dockerfile

1 准备dockerfile文件

新建文件命名为nuttx_Dockerfile，将如下内容拷贝到nuttx_Dockerfile中
镜像中下载了编译开发nuttx的环境

# Ubuntu Dockerfile
#
FROM ubuntu:20.04
LABEL maintainer="pleasecallmekaige<2964073182@qq.com>"
ARG DEBIAN_FRONTEND=noninteractive
ENV TZ=Asia/Shanghai

ADD sources.list /etc/apt/sources.list

RUN apt update | echo 'ignore' \
    && apt -y install apt-transport-https ca-certificates \
    && apt update \
    && apt -y install \
        bison flex gettext texinfo libncurses5-dev libncursesw5-dev \
        gperf automake libtool pkg-config build-essential gperf genromfs \
        libgmp-dev libmpc-dev libmpfr-dev libisl-dev binutils-dev libelf-dev \
        libexpat-dev gcc-multilib g++-multilib picocom u-boot-tools util-linux \
    && apt -y install kconfig-frontends \
    && apt -y install gcc-arm-none-eabi binutils-arm-none-eabi \
    && apt -y install vim \
    && apt -y install python3 python3-pip \
    && pip install -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com compiledb

2 准备一个source.list文件

为了将默认的源改为国内源
准备一个source.list文件内容如下，和nuttx_Dockerfile放在同一个目录下

4 构建镜像

在当前目录下运行如下命令：
构建一个名为nuttx_dev:base的镜像，这个可能耗时会很久

docker build -f nuttx_Dockerfile -t nuttx_dev:base .

5 运行开发环境

1第一次运行时

第一次运行时需要创建容器，运行如下内容：

docker run -it --privileged \
    -v /home/xmk/work/nuttx:/home/xmk/work/nuttx:rw \
    -v /tmp/.X11-unix:/tmp/.X11-unix:ro \
    -e DISPLAY=${DISPLAY} \
    --name=nuttx_dev nuttx_dev:base /bin/bash

划重点：

-v /home/xmk/work/nuttx:/home/xmk/work/nuttx:rw \  #这一句是为了将本地的路径挂载到docker中，这里挂的是nuttx代码存放的位置

2后续每次运行

创建完成后，后面每次就只要打开工作容器

docker start nuttx_dev && docker attach nuttx_dev

6 说明

现在可以用容器中安装的环境编译nuttx啦，和本地环境无关。
由于本地的路径被挂载到容器中，可以用容器里的环境编译本地代码
