在docker网络问题中安装requirements.txt

Question

我正在尝试部署我在docker容器中编写的程序

我写了一篇docker-compose：

version: "2.2"

services:
   web:
     build:
       context: .
       dockerfile: ./Dockerfile
       network: host
     image: myimgname
     container_name: proj_name_container
     volumes:
       - /srv/python/proj_name/trained_model:/tmp/proj_name/trained_model
     ports:
       - "8010:8010"
     environment:
       - PYTHONUNBUFFERED=1

我有这样一个Dockerfile：

FROM tiangolo/uvicorn-gunicorn-fastapi:python3.6

RUN mkdir /tmp/proj_name
ENV SEGPKG=/tmp/proj_name
COPY . $SEGPKG
WORKDIR /
RUN pip install --upgrade pip --proxy https://myproxy:port --trusted-host pypi.python.org

RUN  pip install -r /tmp/proj_name/requirements.txt --proxy https://myproxy:port --trusted-host pypi.python.org

EXPOSE 8010

基于这个pip unable to install packages inside docker container on mac，我添加了--proxy选项

奇怪的是，它对第一个pip install --upgrade pip有效，但对第二个使用我的自定义requirements.txt的pip安装无效。 我收到这个错误：

WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLError(1, '[SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:852)'),)': /simple/aiocontextvars/

重试4次后：

Could not find a version that satisfies the requirement aiocontextvars==0.2.2

我的requirements.txt
