Question

作为学习django的一部分，我正在构建我的第一个docker安装。我的泊坞窗安装正常。 docker信息还可以。和hello-world表示成功。但是，当我运行Will Vincent在我的Django 3.0 Pro Book中建议的Dockerfile时。我收到了看起来像网络DNS错误的信息。

Dockerfile尝试构建：

FROM python:3.7

# Set environment variables
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1

# Set work directory
WORKDIR /code

# Install dependencies
COPY Pipfile Pipfile.lock /code/
RUN pip install pipenv && pipenv install --system

# Copy project
COPY . /code/

在RUN pip安装...行上失败。

我已经将dns域名服务器条目直接添加到了我的/etc/resolver.conf文件中，就像其他在我的搜索中建议的那样。没有用。

我认为Docker试图在容器中运行pip时出现了一些问题？这是我的第一个Docker安装，因此筋疲力尽地寻找答案。

在OS版本Centos8上

谢谢比尔·桑德森

好的，我们可以尝试一些方法。我要做的第一件事：

在Dockerfile中添加以下内容（带有Google的dns）：

RUN echo "nameserver 8.8.8.8" > /etc/resolv.conf && pip install pipenv && pipenv install --system

使用同一RUN命令进行操作很重要。

另一个选择是：

docker build --network=host -t yourimage:yourversion .

尝试点子安装时，docker构建网络错误
