docker集装箱未能拉git回购

使用此引用安装泊坞窗。 我从我们的组织回购拉了一个基本的形象。 未能克隆私人回购。

我能够从terminal手动克隆这个回购，但不是从docker集装箱。 即使我试图用root用户运行docker命令，但没有运气。

$docker build -t foo .

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：

Answer 1

docker build启动一个容器并运行里面的东西，通常它会使用主机的同名服务器，但是容器内部的NMconfiguration似乎出了问题，使得它无法parsinggithub.com ：

无法parsing主机名github.com：名称或服务未知

但是--dns docker build没有选项--dns ，你可以尝试下面的方法：

1. 用--dns选项启动--dns docker daemon ，这会影响包括容器在内的所有--dns操作。

2. 按照这个解决方法为你的docker build设置/etc/resolv.conf ：

   • 在Dockerfile中，编辑/etc/resolv.conf来指向你的自定义DNS
   • 在需要这种自定义DNS的构build操作结束时，恢复正常的容器运行时resolv.conf

希望这可以帮助:-)
