Dockerfile“rm -Rf”失败

我有一个非常简单的dockerfile,安装后用“rm -Rf”删除安装文件,但是我得到了一些错误：

Step 4/4 : RUN rm -Rf /INSTALLATION
 ---> Running in 19fe828f3c9d
rm: cannot remove '/INSTALLATION/Subsystems/Common': Directory not empty
rm: cannot remove '/INSTALLATION/Subsystems/EMS': Directory not empty

我用root用户运行所有.

我的dockerfile：

FROM centos
COPY INSTALLATION/ /INSTALLATION/ 
RUN  rm -Rf /INSTALLATION

我的操作系统是centos7,主机操作系统是RHLE 7.

我也尝试了新的容器并手动尝试,但结果也是错误的：

[root@devvm13 1]# docker run -it e20c9c5ffa8a /bin/bash

[root@f3efa193700d /]# rm -Rf /INSTALLATION/Subsystems/Common/*

[root@f3efa193700d /]# rm -Rf /INSTALLATION/Subsystems/Common 

rm: cannot remove '/INSTALLATION/Subsystems/Common': Directory not empty

你可以看到第二个rm失败,我试过rmdir,resule也是错误的.

当我在目录中时,它显示：

ls /INSTALLATION/Subsystems/Common
ls: cannot access /INSTALLATION/Subsystems/Common/eium-license.config: No such file or directory
ls: cannot access /INSTALLATION/Subsystems/Common/install_jdk.sh: No such file or directory
eium-license.config  install_jdk.sh

你可以说没有这样的文件,但跟着文件.

最佳答案

在花了几个小时发现这个问题之后,我遇到了同样的问题： –
https://github.com/docker/docker/issues/27358

所以长话短说,这就是我修复它的方法.

当您执行docker信息时,在输出中您有存储驱动程序：overlay,我有相同的,我所做的是将overlay更改为devicemapper.按照此处显示的说明进行操作 – https://docs.docker.com/engine/userguide/storagedriver/device-mapper-driver/#configure-docker-with-the-devicemapper-storage-driver

您还必须停止并启动docker服务.

注意：
更改后,您将丢失所有过去的图像,这意味着当您键入docker图像或docker ps时,您将看不到任何图像/容器.他们将在fileSystem中,他们将占用磁盘空间.因此,您必须手动删除该目录,因此它将位于/ var / lib / docker / overlay下.
