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.
Docker信息

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
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
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.
