作为学习django的一部分，我正在构建我的第一个docker安装。我的docker安装工作正常。docker信息正常。hello-world显示成功。但是当我运行Will Vincent在我的Django 3.0 Pro Book中的tourorial建议的Docker文件时，我得到了一个看起来像网络DNS错误的东西。

尝试构建停靠文件：
提取基本图像
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/RUN pip install ....行出现故障。
我已经添加了DNS名称服务器条目直接到我的/etc/resolver. conf文件中，因为其他人在我的搜索这里建议。不工作。
我假设Docker试图在容器中运行PIP时出现了一些问题？？这是我第一次安装Docker，所以用尽了搜索答案。
在操作系统版本Centos8上
谢谢比尔·桑德森

好吧，我们可以尝试几件事。我会做的第一件事：
RUN echo "nameserver 8.8.8.8" > /etc/resolv.conf && pip install pipenv && pipenv install --system在同一个RUN命令中执行此操作非常重要。
docker build --network=host -t yourimage:yourversion .g6ll5ycj2#
我昨晚和今天早上都遇到了同样的问题。甚至在重新启动并试图停止/启动服务之后。这是在我的Windows 10上。
我确实注意到运行
docker info输出时出现以下错误：如此处所述-https://stackoverflow.com/a/74098179/405022
运行了
wsl --shutdown并被提示重新启动docker桌面后，我继续尝试我的docker构建。巧合？最后我成功了。
