1、安装docker和docker-compose

2、配置Dockerfile

FROM python:3.8
ENV PYTHONUNBUFFERED 1
ENV PYTHONDONTWRITEBYTECODE 1

RUN rm -rf /ocr/*

# Allows docker to cache installed dependencies between builds
COPY ./requirements /requirements
RUN pip install -i https://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com --upgrade pip \
  && pip install -r /requirements/local.txt -i https://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com


# Adds our application code to the image
COPY . /ocr
WORKDIR /ocr

EXPOSE 8000

3、配置docker-compose.yml

version: '3'
services:
  ocr_test:
#    platform: linux/amd64
    build:
      context: .
      dockerfile: compose/local/flask/Dockerfile
    command: >
      bash -c "python -m wsgi.py"
    volumes:
      - ./:/ocr
    ports:
      - "8000:8000"

4、项目目录结构

5、打包镜像

docker-compose build

6、启动项目

docker-compose up

因为使用paddleocr这个包，每次启动都要检查参数，使用uwsgi、uvicorn、gunicorn等方式启动都会失败，目前还没有解决方案，现在只能用python直接启动
