运行pip安装：确认ssl证书时出现问题:[ssl:CERTIFICATE_VERIFY_FAILED]证书验证失败[重复]

Question

跟随[GitHub][1]的实验室学习更多关于Docker容器的信息，我感觉到了这个问题：

No matching distribution found for Flask==0.10.1 (from -r /usr/src/app/requirements.txt (line 1))
  Could not fetch URL https://pypi.python.org/simple/flask/: There was a problem confirming the ssl certificate: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:726) - skipping```

这个问题与我在BlueCoat（一种防火墙）后面的一个网络中有关，它检查并隐藏了我的桌面和互联网上的几乎所有通信。

在Feld googles seach之后，我找到了忽略证书问题的命令：

只需将其添加到我的dockerfile--trusted-host pypi.org--trusted-host pypi.python.org--trusted-host=files.pythonhosted.org

# our base image
FROM alpine:3.5

# Install python and pip
RUN apk add --update py2-pip

# install Python modules needed by the Python app
COPY requirements.txt /usr/src/app/
RUN pip install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host=files.pythonhosted.org --no-cache-dir -r /usr/src/app/requirements.txt

# copy files required for the app to run
COPY app.py /usr/src/app/
COPY templates/index.html /usr/src/app/templates/

# tell the port number the container should expose
EXPOSE 5000

# run the application
CMD ["python", "/usr/src/app/app.py"]
