Question

使用此reference安装的泊坞窗。我从我们的组织仓库中提取了基本图像。未能克隆私人仓库。

我可以从终端手动克隆此repo，但不能从docker容器中克隆。甚至我试图用root用户运行docker命令，但没有运气。

$docker build -t foo .

Cleaning up..

更新了DockerFile

FROM my_private_org/base-service:v5-XYZ-ABC

# Set the project name
ENV PROJECT_NAME="project_name" 

# Copy over the source
RUN mkdir -p /workspace/$PROJECT_NAME

WORKDIR /workspace/$PROJECT_NAME

ADD ./requirements.txt /workspace/$PROJECT_NAME/requirements.txt #-- Its failing here

# Install the requirements.txt
RUN yes | pip3 install -r requirements.txt

# ADD the app#
ADD . /workspace/$PROJECT_NAME

更新：

$docker run --rm alpine:3.3 ping -c 3 github.com

docker build启动一个容器并在里面运行，通常它会使用你主机的同名服务器，但是容器内的NM配置似乎出了问题，这使得它无法解决{{1 }}：

无法解析主机名github.com：名称或服务未知

但github.com没有选项docker build，您可以尝试以下方法：

使用--dns选项启动docker daemon，这将影响所有泊坞机操作，包括容器。
关注this workaround为--dns设置/etc/resolv.conf：
- ，编辑/etc/resolv.conf以指向您的自定义DNS
- 在需要此类自定义DNS的构建操作结束时，还原正常的容器运行时resolv.conf

希望这可以提供帮助： - ）
