Python项目打包Docker镜像流程

项目新建Dockerfile文件

把之前写的一个项目后端打包成镜像

cd 项目目录
touch Dockerfile

编写Dockerfile

用python3.10.13作为项目基础镜像。项目开发的时候基于python3.10.13

FROM python:3.10.13

WORKDIR /app

ENV ENV="prod"
ENV TZ=Asia/Shanghai

COPY . /app

RUN pip install poetry
RUN poetry install

CMD ["poetry", "run", "uvicorn", "backend.main:app", "--log-level", "error", "--host", "0.0.0.0", "--port", "8002"]

打包镜像

docker build -t app:0.0.1 .

Use 'docker scan' to run Snyk tests against images to find vulnerabilities and learn how to fix them

测试运行

docker run -d -p 8002:8002 app:0.0.1

curl http://0.0.0.0:8002/utils/anon/ping

# {"ping":"pong"}%

打包好的镜像推到docker hub

# docker login
# 将本地的镜像重新标记为远程仓库地址和镜像名称
docker tag app:0.0.1 zhangwanheng/myapp:0.0.1

docker push zhangwanheng/myapp:0.0.1

The push refers to repository [docker.io/zhangwanheng/myapp]
