Question

在尝试在docker容器中构建我的存储库时，我需要安装git：

FROM ubuntu:14.04
RUN apt-get update
RUN apt-get upgrade
RUN apt-get clean
RUN apt-get install -y git

构建容器我运行以下命令：

sudo docker build .

我尝试安装的每个软件包都出现以下错误：

 E: Unable to locate package git
 The command '/bin/sh -c apt-get install -y git' returned a non-zero code: 100

我找到的所有答案都声称我需要首先运行apt-get update，我这样做。

编辑：

尝试在一行中运行所有命令：

RUN apt-get update && apt-get install -y git

产生了以下错误：

Err http://archive.ubuntu.com trusty InRelease
Err http://archive.ubuntu.com trusty-updates InRelease
Err http://archive.ubuntu.com trusty-security InRelease
Err http://archive.ubuntu.com trusty Release.gpg

Answer 1

从更新的输出中，您显示apt-get update失败，DNS解析失败。这是您需要首先解决的网络连接问题，然后才能构建从网络中提取包的图像。

Answer 2

首先你需要聚合RUN，顺便试试这个：

RUN apt-get -y update &&\
    apt-get -y upgrade &&\
    apt-get install -y --force-yes git &&\
    apt-get clean

当你运行构建时：

sudo docker build -t <name-of-your-image> .

无法在docker容器中找到包
