在构build镜像时，Docker无法删除目录
这个问题类似于Docker在构build映像时无法删除文件
但是，路由的原因是不一样的，因为在我的情况下启用d_type 。
这是Dockerfile
FROM arm64v8/ubuntu:latest RUN export DEBIAN_FRONTEND='noninteractive' && \ rm -rf /var/lib/apt/lists/* /tmp/* /usr/share/doc
当试图build立图像
docker build -t arm64v8-ubuntu-test .
我得到以下错误
Sending build context to Docker daemon 3.584kB Step 1/2 : FROM arm64v8/ubuntu:latest ---> 499b06aa549b Step 2/2 : RUN export DEBIAN_FRONTEND='noninteractive' && rm -rf /var/lib/apt/lists/* /tmp/* /usr/share/doc ---> Running in 5ff328ef5a57 rm: cannot remove '/usr/share/doc/sed': Directory not empty rm: cannot remove '/usr/share/doc/libpam-modules': Directory not empty rm: cannot remove '/usr/share/doc/util-linux': Directory not empty rm: cannot remove '/usr/share/doc/mawk': Directory not empty rm: cannot remove '/usr/share/doc/gnupg': Directory not empty rm: cannot remove '/usr/share/doc/apt': Directory not empty rm: cannot remove '/usr/share/doc/libreadline6': Directory not empty rm: cannot remove '/usr/share/doc/adduser/examples/adduser.local.conf.examples': Directory not empty rm: cannot remove '/usr/share/doc/passwd': Directory not empty rm: cannot remove '/usr/share/doc/mount': Directory not empty rm: cannot remove '/usr/share/doc/procps': Directory not empty The command '/bin/sh -c export DEBIAN_FRONTEND='noninteractive' && rm -rf /var/lib/apt/lists/* /tmp/* /usr/share/doc' returned a non-zero code: 1
我的docker信息是

例如，手动运行容器并尝试执行该命令具有相同的结果
$ docker run --rm -it arm64v8/ubuntu:latest bash root@87a3ea8fecdd:~# rm -rf /var/lib/apt/lists/* /tmp/* /usr/share/doc rm: cannot remove '/usr/share/doc/sed': Directory not empty rm: cannot remove '/usr/share/doc/libpam-modules': Directory not empty rm: cannot remove '/usr/share/doc/util-linux': Directory not empty rm: cannot remove '/usr/share/doc/mawk': Directory not empty rm: cannot remove '/usr/share/doc/gnupg': Directory not empty rm: cannot remove '/usr/share/doc/apt': Directory not empty rm: cannot remove '/usr/share/doc/libreadline6': Directory not empty rm: cannot remove '/usr/share/doc/adduser/examples/adduser.local.conf.examples': Directory not empty rm: cannot remove '/usr/share/doc/passwd': Directory not empty rm: cannot remove '/usr/share/doc/mount': Directory not empty rm: cannot remove '/usr/share/doc/procps': Directory not empty
此外，权限似乎很好，目录是在那里，并没有被其他进程使用

Rmdir也不起作用
root@df3ef4561fc3:/# rmdir /usr/share/doc rmdir: failed to remove '/usr/share/doc': Directory not empty root@df3ef4561fc3:/# lsof /usr/share/doc
直接运行rm命令也是如此
$ docker run --rm -it arm64v8/ubuntu:latest rm -rf /usr/share/doc rm: cannot remove '/usr/share/doc/sed': Directory not empty rm: cannot remove '/usr/share/doc/libpam-modules': Directory not empty rm: cannot remove '/usr/share/doc/util-linux': Directory not empty rm: cannot remove '/usr/share/doc/mawk': Directory not empty rm: cannot remove '/usr/share/doc/gnupg': Directory not empty rm: cannot remove '/usr/share/doc/apt': Directory not empty rm: cannot remove '/usr/share/doc/libreadline6': Directory not empty rm: cannot remove '/usr/share/doc/adduser/examples/adduser.local.conf.examples': Directory not empty rm: cannot remove '/usr/share/doc/passwd': Directory not empty rm: cannot remove '/usr/share/doc/mount': Directory not empty rm: cannot remove '/usr/share/doc/procps': Directory not empty
和sudo
$ sudo docker run --rm -it arm64v8/ubuntu:latest rm -rf /usr/share/doc rm: cannot remove '/usr/share/doc/sed': Directory not empty rm: cannot remove '/usr/share/doc/libpam-modules': Directory not empty rm: cannot remove '/usr/share/doc/util-linux': Directory not empty rm: cannot remove '/usr/share/doc/mawk': Directory not empty rm: cannot remove '/usr/share/doc/gnupg': Directory not empty rm: cannot remove '/usr/share/doc/apt': Directory not empty rm: cannot remove '/usr/share/doc/libreadline6': Directory not empty rm: cannot remove '/usr/share/doc/adduser/examples/adduser.local.conf.examples': Directory not empty rm: cannot remove '/usr/share/doc/passwd': Directory not empty rm: cannot remove '/usr/share/doc/mount': Directory not empty rm: cannot remove '/usr/share/doc/procps': Directory not empty
这不是Docker问题中已知的问题 。 如何进一步debugging问题？
在Docker覆盖存储驱动程序报告为无法从基础图像层＃35257删除目录的问题后，我得到了它的底部，谢谢thaJeztah。
我的系统使用ArchLinuxARM-odroid-c2-latest.tar.gz ，它有一个较旧的内核版本3.14。
发生这个问题是因为ALARM docker软件包默认configuration了overlay驱动程序，只能在较新的内核版本（例如RPi映像或ODROID-C2的主线内核）上运行。
因此，解决scheme是要么
- 升级内核版本。 我上次检查时，ODROID-C2的主线内核支持有问题，所以下一个选项可能会更好。
- 或者将dockerconfiguration为使用AUFS存储驱动程序而不是覆盖驱动程序。
