问题描述

跟着 [GitHub][1] 的实验室了解更多关于 Docker 容器的知识,我在这个问题中感受到了:

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```

解决方案


问题与我位于 BlueCoat(一种防火墙)后面的网络中有关,该网络检查并隐藏了几乎来自我的桌面和 Internet 的通信。

在谷歌搜索后,我发现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"]
