在Dockerfile中的容器内复制文件 [英] Copy file(s) within the container in Dockerfile

问题描述

在docker-compose构建过程中，如何将文件从容器内的路径复制到Dockerfile中同一容器内的不同路径 ?

How can I copy a file from a path within the container to a different path within that same container in a Dockerfile during the docker-compose build process?

COPY <src> <dest>

这将从容器外部的主机复制文件.我不知道如何< src> 指定要复制的容器内的文件.

This copies a file from the host outside the container. I don't know how to have <src> specify a file inside the container to copy.

推荐答案

@tkausl和@JohnKugelman指出可以使用以下命令语法复制文件:

as @tkausl and @JohnKugelman pointed out files can be copied by the following command syntax:

RUN cp <src-path-within-the-container> <dest-path-within-the-container>
