## Docker化部署服务
在日常项目应用中相信大家一般都会希望能通过Docker技术把PaddleOCR服务打包成一个镜像以便在Docker或k8s环境里快速发布上线使用。
本文将提供一些标准化的代码来实现这样的目标。大家通过如下步骤可以把PaddleOCR项目快速发布成可调用的Restful API服务。目前暂时先实现了基于HubServing模式的部署后续作者计划增加PaddleServing模式的部署
## 1.实施前提准备
需要先完成如下基本组件的安装:
a. Docker环境
b. 显卡驱动和CUDA 10.0+GPU
c. NVIDIA Container ToolkitGPUDocker 19.03以上版本可以跳过此步)
d. cuDNN 7.6+GPU
## 2.制作镜像
a.切换至Dockerfile目录需要区分cpu或gpu版本下文以cpu为例gpu版本需要替换一下关键字即可
```
cd deploy/docker/hubserving/cpu
```
c.生成镜像
```
docker build -t paddleocr:cpu .
```
## 3.启动Docker容器
a. CPU 版本
```
sudo docker run -dp 8868:8868 --name paddle_ocr paddleocr:cpu
```
b. GPU 版本 (通过NVIDIA Container Toolkit)
```
sudo nvidia-docker run -dp 8868:8868 --name paddle_ocr paddleocr:gpu
```
c. GPU 版本 (Docker 19.03以上版本,可以直接用如下命令)
```
sudo docker run -dp 8868:8869 --gpus all --name paddle_ocr paddleocr:gpu
```
d. 检查服务运行情况出现Successfully installed ocr_system和Running on http://0.0.0.0:8868 等信息,表示运行成功)
```
docker logs -f paddle_ocr
```
## 4.测试服务
[Cherry-pick] Cherry-pick from release/2.6 (#11092) * Update recognition_en.md (#10059) ic15_dict.txt only have 36 digits * Update ocr_rec.h (#9469) It is enough to include preprocess_op.h, we do not need to include ocr_cls.h. * 补充num_classes注释说明 (#10073) ser_vi_layoutxlm_xfund_zh.yml中的Architecture.Backbone.num_classes所赋值会设置给Loss.num_classes, 由于采用BIO标注,假设字典中包含n个字段(包含other)时,则类别数为2n-1;假设字典中包含n个字段(不含other)时,则类别数为2n+1。 * Update algorithm_overview_en.md (#9747) Fix links to super-resolution algorithm docs * 改进文档`deploy/hubserving/readme.md`和`doc/doc_ch/models_list.md` (#9110) * Update readme.md * Update readme.md * Update readme.md * Update models_list.md * trim trailling spaces @ `deploy/hubserving/readme_en.md` * `s/shell/bash/` @ `deploy/hubserving/readme_en.md` * Update `deploy/hubserving/readme_en.md` to sync with `deploy/hubserving/readme.md` * Update deploy/hubserving/readme_en.md to sync with `deploy/hubserving/readme.md` * Update deploy/hubserving/readme_en.md to sync with `deploy/hubserving/readme.md` * Update `doc/doc_en/models_list_en.md` to sync with `doc/doc_ch/models_list_en.md` * using Grammarly to weak `deploy/hubserving/readme_en.md` * using Grammarly to tweak `doc/doc_en/models_list_en.md` * `ocr_system` module will return with values of field `confidence` * Update README_CN.md * 修复测试服务中图片转Base64的引用地址错误。 (#8334) * Update application.md * [Doc] Fix 404 link.

a. 计算待识别图片的Base64编码如果只是测试一下效果可以通过免费的在线工具实现http://tool.chinaz.com/tools/imgtobase/
2020-12-09 23:32:12 +08:00
b. 发送服务请求可参见sample_request.txt中的值
```
curl -H "Content-Type:application/json" -X POST --data "{\"images\": [\"填入图片Base64编码(需要删除'data:image/jpg;base64,'\"]}" http://localhost:8868/predict/ocr_system
```
c. 返回结果(如果调用成功,会返回如下结果)
```
{"msg":"","results":[[{"confidence":0.8403433561325073,"text":"约定","text_region":[[345,377],[641,390],[634,540],[339,528]]},{"confidence":0.8131805658340454,"text":"最终相遇","text_region":[[356,532],[624,530],[624,596],[356,598]]}]],"status":"0"}
