Amazon GreenGrass + OpenVINO 環境架設

環境

* Ubuntu 16.04 - x86
* Docker 17.05.0-ce, build 89658be

準備下列檔案

* [ Amazon GreenGrass 1.7.1 ] ( https://d1onfpft10uf5o.cloudfront.net/greengrass-core/downloads/1.7.1/greengrass-linux-x86-64-1.7.1.tar.gz )
* [ OpenVINO 2018-05-455 ] ( http://registrationcenter-download.intel.com/akdlm/irc_nas/15078/l_openvino_toolkit_p_2018.5.455.tgz )
* supervisor.config
* sysctl.conf
* Docker File

部署

1. 將上述所需檔案放置同一目錄

2. Docker build

    docker build --build-arg "greengrass_release=greengrass-linux-x86-64-1.7.0.tar.gz" .

3. 進入Container 
   *(因為OpenVINO安裝時，需要手動設置選項，所以無法自動安裝)

    docker run -it {ID} /bin/bash

4. 安裝OpenVINO 所需套件

    apt-get install -y lsb-release sudo cpio vim lsb-core

5. 安裝OpenVINO

    tar xvf l_openvino_toolkit_p_2018.5.455.tgz -C /tmp
    cd /tmp/l_openvino_toolkit_p_2018.5.455
    ./install_cv_sdk_dependencies.sh
    ./install.sh

  安裝以下套件
  Options > Component selection

  1. Accept and continue [ default ]
  2. [x] Inference Engine (already installed)
  3. [x] Model Optimizer (already installed)
  4. [x] OpenCV*
  5. [x] OpenVX*
  6. [ ] Models
  7. [x] Algorithms
  8. [x] Intel(R) Media SDK (already installed)

  Install space required:  770MB

6. 設定環境變數

      source /opt/intel/computer_vision_sdk/bin/setupvars.sh
      cd /opt/intel/computer_vision_sdk/deployment_tools/inference_engine/samples
      ./build_samples.sh

7. 刪除不必要的檔案，減少Image容量

    apt-get purge libx11.* libqt.* #移除 ubuntu-x11
    apt-get purge dpkg -l | grep ^rc | awk '{ print $2 }'
    apt-get autoremove
    find / -name *.a
    rm /opt/intel/computer_vision_sdk_2018.5.455/openvx/samples/
    rm -rf /opt/intel/computer_vision_sdk_2018.5.455/deployment_tools/inferen ce_engine/lib/ubuntu_18.04/
    rm -rf /opt/intel/computer_vision_sdk_2018.5.455/deployment_tools/inference_engine/lib/centos_7.4/
    apt-get install libgtk2.0-0
