apt-get不能在Dockerfile中工作 [英] apt-get not working in Dockerfile

问题描述

ANSWER ：我仍然不知道什么是错误的，但是在重新启动docker并再次运行（同样的Dockerfile，相同的一切）之后，它工作正常。

我在Windows上使用Docker，而Dockerfile是

  FROM ubuntu：15.04 
 
 COPY。 / src 
 
运行apt-get更新
运行apt-get install -y nodejs 
 ... etc 
  

但是当我尝试构建图像时，我得到

  WARN [ 0001]安全警告：您正在从Windows Docker主机上构建Docker映像。添加到构建上下文中的所有文件和目录将具有'-rwxr-xr-x'权限。建议对敏感文件和目录进行双重检查和重置权限
 
 ... 
 
步骤3：运行apt-get -y update

步骤4：运行apt-get install -y nodejs

apt-get工作，但是当我尝试将其他apt-get安装行放在那些不工作的时候，所以似乎不是一个问题，

谢谢！

解决方案

我重新启动了docker并再次尝试，现在可以正常工作。 $ b

ANSWER: I still don't know what was really wrong but after I restarted docker and ran it again (same dockerfile, same everything), it worked fine.

I'm using Docker on Windows and my Dockerfile is

RUN apt-get update 
RUN apt-get install -y nodejs 
...etc

but when I try to build the image I get

apt-get works but when I try to put other apt-get install lines in those don't work either so it doesn't seem to be a problem with

Thanks!
