apt-get 命令在 docker 容器中不起作用

Question

我正在尝试在 docker 映像中安装一些软件包，但 apt-get 命令似乎不起作用......

当我在基于 ubuntu:16.04 的容器中尝试此操作时

apt-get update && apt-get install -y openssh-server

我懂了：

Err:2 http://security.ubuntu.com/ubuntu zesty-security InRelease

我尝试在这样的 Dockerfile 中执行此操作

FROM ubuntu:16.04
RUN apt-get update && apt-get -y install openssh-server
CMD bin/bash

并用

sudo docker build -t imagetest .

但我得到了这个：

我在官方文档和一些论坛上进行了搜索，但我找到的答案都没有帮助我并且已经过时了...

有些人说要重启docker服务，但对我不起作用.. 其他人说要使用apt-get update -qq，但它也不起作用...

所以我来这里直接询问，并有一个最近的答案。

谢谢。

如果 apt-get 在虚拟机上工作正常，您可以使用网络主机模式构建容器。

docker build --network=host ...
