Docker在构建映像时无法删除文件

本文介绍了Docker在构建映像时无法删除文件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我的DockerFile包含以下指令：

My DockerFile contains the following instruction:

rm -f plugins.7z

此命令在Docker的早期版本中按预期工作，但在1.13版本中失败。我看到错误：

This command worked as expected in earlier versions of docker but fails with version 1.13. I see the error:

cannot access plugins.7z: No such file or directory

如果我打开一个带有基本映像的容器并手动执行命令，则会看到相同的错误。

If I bring up a container with the base image and execute the command manually, I see the same error.

试图列出文件夹内容显示：

Trying to list the folder contents displays:

# ls -lrt
  ls: cannot access plugins.7z: No such file or directory
  total 12
  ???????????   ? ?          ?             ?            ? plugins.7z

在。如何进一步调试问题？

This is not listed as a known issue in Docker Issues. How do I debug the issue further?

编辑：

出于IP的原因，我无法发布完整的Dockerfile这里。同样，可能没有必要。如前所述，即使手动运行容器并尝试执行命令，我也可以模拟问题。

在尝试删除该文件之前，该文件已存在

我错了，因为问题列表中没有类似的错误。这是

该问题可能不会与该文件有关。删除文件夹中的其他文件/文件夹也会使它们显示为???。权限

执行操作的用户是root

For reasons of IP, I cannot post the full Dockerfile here. Also, it may not be necessary. As I mentioned, I am able to simulate the issue even by manually running the container and trying to execute the command
The file exists before I attempt to delete it
I was wrong about there not being a similar bug in the issues list. Here is one
The issue may not be to do with that file. Deleting other files/folders in the folder also makes them appear with ??? permissions
The user performing the operation is root

推荐答案

删除目录失败的原因是未使用d_type支持（ ftype = 1）格式化支持（ xfs ）文件系统；您可以在github上找到讨论；。

The reason removing directories fails is that the backing (xfs) filesystem was not formatted with d_type support ("ftype=1"); you can find a discussion on github; https://github.com/docker/docker/issues/27358.

要验证系统上是否提供 d_type 支持，请检查 docker的输出信息;

To verify if d_type support is available on your system, check the output of docker info;

Server Version: 1.13.1
Storage Driver: overlay
 Backing Filesystem: xfs
 Supports d_type: false
Logging Driver: json-file

也可以解决该问题；

使用 ftype = 1

使用其他存储驱动程序。请注意，不建议将默认设备映射器配置（使用环回设备）用于生产，因此需要手动配置。

-compatibility（较旧版本的docker允许在没有 d_type 的系统上运行叠加），docker 1.13只会在守护程序日志中记录 warning （），但不会在以后的版本中不再受支持。

For backward-compatibility (older versions of docker allowed running overlay on systems without d_type), docker 1.13 will only log a warning in the daemon logs (https://github.com/docker/docker/pull/27433), but will no longer be supported in a future version.
