====== Paperless-ngx 文件管理系統(Docker)  ======
  * 之前就一直找尋可以快速搜尋 File Server 內檔案內文關鍵字的系統, 最近看到這套 Paperless-ngx 還具有OCR的功能, 連掃描產生的 PDF 內文都可以解析出內文, 真的就很符合我希望使用的情境.
  * 安裝環境 :
    * VM : 4 vCores / 8G RAM / 32G(SSD)+500G(HDD)
    * OS : [[tech/alpine_docker|Alpine3 + Docker Compose]]
    * 配置 : 將 500G 掛在 /data 目錄上, 作為存放資料使用

===== 安裝方式 =====
  - 下載 docker-compose.env 與 docker-compose.yml <cli>
wget https://raw.githubusercontent.com/paperless-ngx/paperless-ngx/dev/docker/compose/docker-compose.env -O docker-compose.env
wget https://raw.githubusercontent.com/paperless-ngx/paperless-ngx/dev/docker/compose/docker-compose.postgres.yml -O docker-compose.yml
</cli>
  - 修改 docker-compose.env <cli>
vi docker-compose.env
</cli>
    * 增加繁體中文 OCR 辨識功能<file>
PAPERLESS_OCR_LANGUAGES=chi-tra chi-tra-vert
</file>
    * 修改網址 Exp. docs.my.ichiayi.com<file>
PAPERLESS_URL=https://docs.my.ichiayi.com
</file>
    * 修改時區<file>
PAPERLESS_TIME_ZONE=Asia/Taipei
</file>
    * 修改預設 OCR為繁體中文+英文<file>
PAPERLESS_OCR_LANGUAGE=chi_tra+eng
</file>
  - 設定 Reverse Proxy(Option) Exp. docs.my.ichiayi.com -> http 172.16.0.220 8000
  - 修改 docker-compose.yml 來支援 Office 格式, 以及增加 time out 時間, 資料存放到 /data <cli>
vi docker-compose.yml
</cli><file>
