制作ubuntu18.04 cuda10.2+ROS1+opencv 4.5.4的 docker镜像

如果搭建的版本高可以参考：
https://gitlab.com/nvidia/container-images/l4t-jetpack.git
如果版本比较低，按照下面的步骤进行操作：
使用的硬件平台为Xavier NX，系统环境如下图：
搭建docker环境需求跟实际环境一致如下图：
在这里插入图片描述从官网获取cuda10.2版本只有支持x86的，如下网站:
https://developer.nvidia.com/cuda-10.2-download-archive
下面从sdk manager中获取方法的进行从论坛中获取：

https://forums.developer.nvidia.com/t/how-to-install-cuda-10-2-to-jetson-tx2/241479/3

小知识：

docker去掉sudo方法：

sudo groupadd docker
sudo usermod -aG docker $USER
sudo systemctl restart docker
newgrp docker
id $USER

docker容器启动时，会执行/root/.bashrc。所以自启动的东西可以在/root/.bashrc中进行添加。
编译依赖cuda，可设置路径 CUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda-10.2
安装docker buildx： sudo apt install docker-buildx && docker buildx install

1. 下载安装包

现在使用的SDK Manager版本为2.1.0.直接打开软件，看到最老的版本只能到4.6.3，如下图：
在这里插入图片描述
如果要使用老的JETPACK，如上图我们要使用4.6的版本。我们可以使用下面命令打开SDK Manager：

sdkmanager --archived-versions

打开后可以看到老版本如下图：
在这里插入图片描述
然后按照正常SDK Manager下载流程下载JETPACK安装包，如下（只下载不进行烧录，等待下载完成）：

2. 下载基础镜像
基础镜像地址：https://catalog.ngc.nvidia.com/orgs/nvidia/containers/l4t-base/tags
可以在网站上下载基础docker镜像，如需求32.6.1版本，那么我们使用docker拉取基础镜像：

docker pull nvcr.io/nvidia/l4t-base:r32.6.1

3. 启动容器（运行脚本start_docker.sh，内容如下：）

#!/bin/bash

docker run -it \
    --rm \
    -v $(pwd)/:/opt/ws/ \
    -v /home:/home \
    -v /etc/localtime:/etc/localtime:ro \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    -e DISPLAY=unix$DISPLAY \
    -w /opt/ws/ \
    --hostname tn \
    nvcr.io/nvidia/l4t-base:r32.6.1

4. 安装基本环境

在docker中基于ubuntu18.04 安装ros
更新source源

apt-get update

安装sudo 和 lsb_release工具

apt-get install sudo
apt-get install -y vim
sudo apt-get install -y lsb-core
sudo apt install -y python-pip
sudo apt install -y  python3-pip

向ros源中添加ros源地址，并配置公钥，如果rosdep update执行失败，可以尝试多试几次.

sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'
sudo apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654
sudo apt update
sudo apt install -y ros-melodic-desktop-full
sudo apt install python3-rosdep
sudo rosdep init
sudo rosdep update
source /opt/ros/melodic/setup.sh

rosdep update后正确的打印如下：

root@tn:/opt/ws/work# sudo rosdep update
reading in sources list data from /etc/ros/rosdep/sources.list.d
Warning: running 'rosdep update' as root is not recommended.
  You should run 'sudo rosdep fix-permissions' and invoke 'rosdep update' again without sudo.

因为我们工程使用的是python3.6，所以将python软连接到python3.8

bashroot@tn:/usr/bin# rm -f python
root@tn:/usr/bin# ln -s python3.6 python

安装cuda
通过sdk manager下载下来的deb包来安装cuda。可以参考https://developer.ridgerun.com/wiki/index.php/Installing_CUDA-toolkit_and_VisionWorks_Jetson_TX2/Xavier/Nano
下面可以解决（#include <NvInfer.h>缺失问题）：

sudo dpkg -i cuda-repo-l4t-10-2-local_10.2.460-1_arm64.deb
sudo apt-key add /var/cuda-repo-l4t-10-2-local/7fa2af80.pub
sudo apt-get update
sudo apt-get install cuda-toolkit-10-2
sudo dpkg -i cuda-repo-cross-aarch64-ubuntu1804-10-2-local_10.2.460-1_all.deb
sudo dpkg -i libcudnn8_8.2.1.32-1+cuda10.2_arm64.deb
sudo dpkg -i libnvinfer8_8.0.1-1+cuda10.2_arm64.deb
sudo dpkg -i libcudnn8-dev_8.2.1.32-1+cuda10.2_arm64.deb
sudo dpkg -i libnvinfer-dev_8.0.1-1+cuda10.2_arm64.deb

安装opencv 4.5.4
下载opencv4.5.4和opencv_contrib4.5.4版本，将opencv_contrib4.5.4放置在opencv目录下，可以参考：
https://developer.ridgerun.com/wiki/index.php/Compiling_OpenCV_from_Source

-- Configuring done

编译并安装

make -j8
make install

配置docker，并导出镜像文件。

docker commit -a "tn" -m "drone in xavier nx ubuntu18.04" clever_varahamihira drone-xavier-nx-ubuntu18.04-v1:r32.6.1
docker save -o drone_melodic_xavier_nx_v1.tar drone-xavier-nx-ubuntu18.04-v1:r32.6.1

8.其他设备进行加载。

docker load -i drone_melodic_xavier_nx_v1.tar

编译出现的错误如下：
