Question

我在尝试重建某些docker容器时遇到了非常奇怪的行为。构建在以下行失败：

COPY ./startup.sh /

我收到以下错误：

Step 15 : COPY ./startup.sh /
stat /var/lib/docker/aufs/mnt/03a7dbf0115dabea5d4cb0ee7ebc84fe79254066089e50e8a7fb55c0c31d8c8d/startup.sh: no such file or directory

该文件在当前目录中可用，也没有dockerignore文件：

$ ls -al

-rwx------  1 user user 4839500 Jul 13 13:33 tools-1.0-SNAPSHOT.jar

有两点我感兴趣：

看起来它与目的地有关。当我将COPY指令修改为这样的内容时：COPY ./startup.sh /foo.sh它抱怨/var/lib/docker/aufs/mnt/.../foo.sh不在那里。
将内容复制到其他导演中而不是/正常工作，如下面的说明：

COPY ./tomcat-users.xml / usr / local / tomcat / conf / COPY ./*.war / usr / local / tomcat / webapps /

这里真正奇怪的是，几周前构建工作正常，但现在它失败了，除了没有更改文件和文件夹。

任何帮助或指示将不胜感激。谢谢！

首先尝试在另一台计算机或VM中构建Dockerfile。您的错误看起来像aufs图层中的损坏。如果它在另一台机器上成功，则需要清理docker。这个答案谈到了重置docker：click here

此致

Answer 2

对于我的泊坞窗构建错误，

COPY failed: stat /<**path**> :no such file or directory

我通过重启docker服务来解决这个问题。

sudo service docker restart

Dockerfile中现有文件的COPY神秘失败
