Tilde扩展在Docker COPY命令中不起作用 [英] Tilde Expansion Doesn't Work in Docker COPY Command

问题描述

我有一个带有以下行的Dockerfile：

I have a Dockerfile with the following line:

COPY *.zip ~user1

用户 user1 已经存在并具有主目录（即 / home / user1 ）。当然，目标是将zip文件复制到该用户的主目录中，但是上述结果是将zip文件复制到一个名为 /〜user1

The user user1 already exists and has a home directory (i.e. /home/user1). The goal, of course, is to copy the zip file into that user's home dir, however the result of the above is that the zip file is copied to a file named literally /~user1 in the image.

以下功能确实可以正常工作：

The following does work as expected:

COPY *.zip /home/user1

这是Docker中的错误还是我不知道与波浪号扩展有关的限制？

Is this a bug in Docker or is there a limitation related to tilde expansion that I'm not aware of?

在Mac上使用Docker 1.13.0。

推荐答案

不支持 COPY 的字幕扩展。

来自复制文档：

目的地是绝对路径，或路径相对于WORKDIR，将源复制到目标容器中。

The dest is an absolute path, or a path relative to WORKDIR, into which the source will be copied inside the destination container.

示例：

COPY test relativeDir/   # adds "test" to `WORKDIR`/relativeDir/
COPY test /absoluteDir/  # adds "test" to /absoluteDir/
