作者提供的dockerfile有问题，可以参考以下的Dockerfile

git clone https://github.com/sml2h3/ddddocr-fastapi.git
cd ddddocr-fastapi
docker build -t ddddocr-api .
docker run -d -p 8000:8000 --name ddddocr-api-container ddddocr-api
##或者使用docker-compose方式
docker-compose down && docker-compose build && docker-compose up -d
