我正试图使用Dockerfile构建一个小型导出，其中包含Perl、curl和git，以便与GitHub一起作为chroot环境使用。任何将curl或git放入Dockerfile的尝试都会从导出的tar文件中删除目录。我可以将Perl与Firefox等其他软件包结合起来，最终得到一个可用的tar

这是Dockerfile。如前所述，如果我只要求Perl或其他任何东西，但不要求使用Perl实现curl/git，那么它确实有效

FROM gliderlabs/alpine:3.4

RUN apk add --update \
    curl \
    perl-dev \
    git \
  && rm -rf /var/cache/apk/*

ENTRYPOINT ["/usr/bin/perl", "-de0"]

欢迎有任何见解

有几件事需要尝试

为每次安装尝试其他“运行”命令
在每个步骤之后删除缓存
在构建docker映像时，请使用“无缓存”选项<代码>docker构建-无缓存

我运行了您的Dockerfile，没有问题：

$ cat df.alpine
FROM gliderlabs/alpine:3.4

RUN apk add --update \
    curl \
    perl-dev \
    git \
  && rm -rf /var/cache/apk/*

您似乎没有提供足够的详细信息来重现您的问题。

我希望在tar文件中看到这些。我生成的tar文件只包含bin、dev和etc顶级文件夹……我在其中找不到perl、curl或git可执行文件。下面是一组用于导出以在GitHub中使用的命令。
docker build-f docker.perl-t docker.perl。docker create——名称docker.perl docker.perl/bin/true docker export docker.perl | gzip>docker.perl.tar.gzhhello。谢谢你检查这个。我无法在Windows10Pro上使用Docker for Windows，也无法在Windows10Home上使用Docker工具箱。我可以尝试在Linux计算机上构建导出，看看这是否是导致我悲伤的原因。您好：问题是，在Windows中使用WinRar验证生成的导出时，符号链接没有正确解析，导致文件似乎丢失。当只添加perl时，没有符号链接，因此在验证文件时没有问题。感谢您指出它确实是在Linux下正确构建的。在那之后，我意识到符号链接让我担心。IskiE@IskieIsketerol谢谢你的跟进，很高兴听到Docker没有崩溃，至少是这样。在Linux上本机运行Docker确实为我消除了许多其他人遇到的问题。谢谢。我确实试过每一种。如上所述，我导出的tar文件不包含可执行文件。
