无法替换docker中的软件源码Ubuntu镜像

Question

我在docker上安装了Ubuntu 14.04镜像。该镜像带有Ubuntu官方软件源码。由于我在中国，无法连接到这些服务器，因此我必须编辑etc/apt/source.list用vi或vim替换软件源。但是，Ubuntu映像不会与两个编辑器中的任何一个一起提供。如果我尝试 来安装编辑器，那么我必须更改软件源。我怎么解决这个问题？

Answer 1

如下您可以创建一个派生泊坞窗图像：

Dockerfile

FROM ubuntu:14.04 
COPY ./sources.list /etc/apt/ 

sources.list（我在中国使用这些之前，他们的工作很好，跟你喜欢的人替换）

创建这些文件后，您可以通过运行来构建映像，例如：

docker build --tag ubuntu:14.04-cn 

并在您的项目中使用它，如果您需要将其上传到码头集线器，则需要相应地更改名称。

此外，我建议您直接在图像中安装所需的软件，这样您不必在每次启动容器时都安装依赖项，因为无论如何您都在构建图像。
