Docker：更改目录命令(Change directory command in Docker?)

Docker：更改目录命令(Change directory command in Docker?)

在码头我想做这个：

git clone XYZ cd XYZ make XYZ

但是由于没有cd命令，我必须每次都通过完整路径（使XYZ / fullpath）。 有什么好的解决方案吗？

In docker I want to do this:

git clone XYZ cd XYZ make XYZ

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

您可以对RUN运行脚本或更复杂的参数。 以下是我下载的Dockerfile的一个例子：

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

实际上，由于每个RUN都会创建一个新的commit＆（当前）一个AUFS层，如果在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）可以是非常有用的事情要做

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

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

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.
