Dockerfile:COPY/ADD路径中带有空格字符(Windows) [英] Dockerfile: COPY / ADD with space character in path (Windows)
问题描述
在Windows 10(cmd)中，我正在尝试从子文件夹中复制文件，该子文件夹的名称中包含空格字符.
In Windows 10 (cmd) I'm trying to copy a file from a subfolder containing a space character in its name.

首先，我尝试使用引号:
First I tried to use quotation marks:
FROM jfloff/alpine-python:2.7
COPY "Folder 1/File.txt" "Dir 1"
错误消息:
无法处理"\"文件夹":查找匹配的双引号时语句意外结束
failed to process "\"Folder": unexpected end of statement while looking for matching double-quote
"JSON"格式(跳过第一行):
"JSON" format (skipped the first line):
COPY ["Folder 1/File.txt" "Dir 1"]
错误消息:
无法处理"[\"文件夹":查找匹配的双引号时语句意外结束
failed to process "[\"Folder": unexpected end of statement while looking for matching double-quote
尝试使用单个反斜杠进行转义:
Trying to escape with a single backslash:
COPY "Folder\ 1/File.txt" "Dir\ 1"
错误消息:
无法处理"\"文件夹\\":查找匹配的双引号时语句意外结束
failed to process "\"Folder\\": unexpected end of statement while looking for matching double-quote
试图以双反斜杠转义:
Trying to escape with a double backslash:
COPY "Folder\\ 1/File.txt" "Dir\\ 1"
错误消息:
无法处理"\"文件夹\\\\":查找匹配的双引号时语句意外结束
failed to process "\"Folder\\\\": unexpected end of statement while looking for matching double-quote
还尝试了使用％20 代替空格的建议:
COPY ["Folder%201/File.txt" "Dir%201"]
错误消息:
复制失败:没有源文件
COPY failed: no source File
转义符替换:
Escape character replacement:
# escape=`
COPY "Folder` 1/File.txt" "Dir 1"
错误消息:
无法处理"\" Folder`":查找匹配的双引号时语句意外结束
failed to process "\"Folder`": unexpected end of statement while looking for matching double-quote
相同，但没有引号:
The same, but without quotes:
#escape=`
COPY Folder` 1/File.txt Dir` 1
错误消息:
复制失败:stat/var/lib/docker/tmp/docker-builder082039614/文件夹:没有此类文件或目录
使用 tar 归档文件打包/解包的方法(我对该想法不满意).
Method with packing / unpacking using a tar archive (I'm not happy with that idea).
应该有可能，不是吗?
推荐答案
也许您可以使用 ARG 来帮助您，就像这样:
Maybe you can use ARG to help you, like this:
Dockerfile:
FROM jfloff/alpine-python:2.7
ARG src="Folder 1/File.txt"
ARG target="Dir 1/"
COPY ${src} ${target}
顺便说一句，如果您真的想将其视为文件夹，则必须在 Dir 1 的末尾添加/.
BTW, a / has to be add at the end of Dir 1 if you treat really want to treat it as a folder.
而且，JSON格式也可以，只要您错过，，它应该是:
And, JSON format is also ok, just you miss ,, it should be:
FROM jfloff/alpine-python:2.7
COPY ["Folder 1/File.txt", "Dir 1/"]
更新您的评论:
在官方指南中，它说:
复制包含特殊字符(例如[和])的文件或目录时，需要遵循Golang规则转义那些路径，以防止将它们视为匹配模式.
When copying files or directories that contain special characters (such as [ and ]), you need to escape those paths following the Golang rules to prevent them from being treated as a matching pattern.
因此，对于您的情况，应该是:
So, for your case, it should be:
FROM jfloff/alpine-python:2.7
ARG src="[[]Folder 1]/__SLIM_TEMPLATE.mm"
ARG target="[Folder 1]/"
COPY ${src} ${target}
或者:
FROM jfloff/alpine-python:2.7
COPY ["[[]Folder 1]/__SLIM_TEMPLATE.mm", "[Folder 1]/"]
