docker教程如何安装包

Question

我只是在关注 docker 的 getting started，我有点迷路了。
我在我的文档中创建了一个 mydockerbuild 文件夹，并使用此代码（来自教程）创建了一个 docker 文件

FROM docker/whalesay:latest
RUN apt-get -y update && apt-get install -y fortunes
CMD /usr/games/fortune -a | cowsay

然后按照教程我运行这个命令：

docker build -t docker-whale .

我收到以下错误：

Sending build context to Docker daemon 2.048 kB
Step 0 : FROM docker/whalesay:latest

The command '/bin/sh -c apt-get -y update && apt-get install -y fortunes' returned a non-zero code: 100

我认为错误来自 apt-get update 但当我在我的计算机上执行时我没有问题。
我运行宁 ubuntu 14.04

Answer 1

您可以尝试根据错误消息调整您的更新命令：

Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

Answer 2

所以我发现了问题，错误是容器内的连接问题。

我已经为不使用个人 wifi 网络的人找到了关于此问题的其他主题。

所以我只是运行使用来自 phone 的 3G 的命令并且它有效。
