Docker：更改目录命令 [英] Docker: change directory command

问题描述

在docker中我想这样做：

In docker I want to do this:

git clone XYZ
cd XYZ
make XYZ

但是由于没有cd命令，我必须每次都传入完整路径（使XYZ /完整路径）。任何好的解决方案？

However because there is no cd command, I have to pass in the full path everytime (make XYZ /fullpath). Any good solutions for this?

推荐答案

您可以运行脚本或更复杂的参数到RUN。以下是我先前下载的Docker文件的一个例子：

You can run a script, or a more complex parameter to the RUN. Here is an example from a Dockerfile I've downloaded to look at previously:

RUN cd /opt && unzip treeio.zip && mv treeio-master treeio && \
    rm -f treeio.zip && cd treeio && pip install -r requirements.pip

由于使用'&&'，它将如果所有以前的命令都成功，只能进入最终的pip install命令。

Because of the use of '&&', it will only get to the final 'pip install' command if all the previous commands have succeeded.

事实上，由于每个RUN都会创建一个新的commit& （当前）一个AUFS图层，如果您在Dockerfile中有太多的命令，那么您将使用限制，因此合并RUN（当文件稳定时）可能是一件非常有用的事情。

In fact, since every RUN creates a new commit & (currently) an AUFS layer, if you have too many commands in the Dockerfile, you will use up the limits, so merging the RUNs (when the file is stable) can be a very useful thing to do.
