FPGA云原生 Xilinx FPGA_as_a_Service之Xilinx Base Runtime脚本分析 /utilities/docker_install.sh

Xilinx FPGA_as_a_Service之Xilinx Base Runtime脚本分析 host_setup.sh运行会调用/utilities/docker_install.sh脚本安装docker。在该产品中有一个Dockerfiles文件夹。目录结构如下所示，针对不同的版本的XRT有不同的文件夹，文件夹下有针对不同操作系统的

Dockerfile文件，用于创建镜像。

首先是确认运行用户是root，然后确认系统是否已经安装docker了。如果已经安装，打印docker版本；如果没有安装，

if [[ $EUID -ne 0 ]]; then
   echo "This script must be run as root. " 
   exit 1
fi

OSVERSION=`grep '^ID=' /etc/os-release | awk -F= '{print $2}' | tr -d '"'`

if [[ "$OSVERSION" == "ubuntu" ]]; then
   DOCKER_INFO=`apt list --installed 2>/dev/null | grep docker-ce`
elif [[ "$OSVERSION" == "centos" ]]; then
   DOCKER_INFO=`yum list installed 2>/dev/null | grep docker-ce`
else
   echo "The script supports: Ubuntu 16.04, Ubuntu 18.04 and Centos 7. For other operating system, please install DockerCE manually following: https://docs.docker.com/engine/install/."
   exit 1
fi

if [ $? == 0 ] ; then
   echo "You have already installed docker."
   DOCKER_INFO=`docker info 2>/dev/null`
   if [ $? == 0 ] ; then
      DOCKER_VERSION=`docker info 2>/dev/null |grep "Server Version"| awk -F: '{print $2}'`
      echo "Docker Version:$DOCKER_VERSION"
   else
      docker info
   fi
else
   echo "Install docker on $OSVERSION..."
   if [[ "$OSVERSION" == "ubuntu" ]]; then
      apt-get -y update && apt-get install -y curl
   fi
   curl -fsSL https://get.docker.com | sh > /tmp/xxappstore_hostsetup_installdocker.log 2>&1
   if [[ $? != 0 ]]; then
      echo "[ERROR] Unable to install DockerCE using Docker automated script"
      echo "Please install DockerCE manually following this documentation:"
      if [[ "$OSVERSION" == "ubuntu" ]]; then
         echo ' > [UBUNTU] https://docs.docker.com/install/linux/docker-ce/ubuntu/'
      elif [[ "$OSVERSION" == "centos" ]]; then
         echo ' > [CENTOS] https://docs.docker.com/install/linux/docker-ce/centos/'
      fi
      exit 1
   fi
   echo "Configure docker"
   mkdir -p /etc/docker && echo '{"max-concurrent-downloads": 1}' | tee -a /etc/docker/daemon.json && systemctl restart docker && systemctl enable docker > /tmp/xxappstore_hostsetup_configuredocker.log 2>&1
   if [[ $? != 0 ]]; then
      echo "[ERROR] Docker Configuration. Check log file /tmp/xxappstore_hostsetup_configuredocker.log"
      exit 1
   fi
   echo "Verify that Docker Engine is installed correctly by running the hello-world image."
   echo ""
   echo "    docker run hello-world"
   echo ""
   echo "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:"
   echo ""
   echo "    usermod -aG docker your-user"
   echo ""
   echo "Install docker completed"
fi

分析一下如下命令
mkdir -p /etc/docker && echo ‘{“max-concurrent-downloads”: 1}’ | tee -a /etc/docker/daemon.json && systemctl restart docker && systemctl enable docker > /tmp/xxappstore_hostsetup_configuredocker.log 2>&1

Dockerfile文件，以201902 centos举例
