无法构build泊坞窗图像，“必须是root用户”
我正在通过在容器中安装应用程序（应该是安装的根用户）来创build一个Docker镜像。
# cat Dockerfile FROM ubuntu:16.04 COPY $pwd/intel_virtual_gateway_console64_1_9_0.tar /root/ COPY $pwd/login.exp /root/ WORKDIR /root/ RUN tar -xvf intel_virtual_gateway_console64_1_9_0.tar RUN apt-get update && apt-get install -y expect \ expect-dev \ libxml2-utils RUN whoami RUN expect login.exp Docker镜像的构build过程：
root@labadmin-VirtualBox:~/RAGHU/krishna# docker build -t release:4.0 . Sending build context to Docker daemon 633.5MB Step 1/8 : FROM ubuntu:16.04 ---> 6a2f32de169d Step 2/8 : COPY $pwd/intel_virtual_gateway_console64_1_9_0.tar /root/ ---> Using cache ---> 36e9ea407082 Step 3/8 : COPY $pwd/login.exp /root/ ---> Using cache ---> 0fad538973d4 Step 4/8 : WORKDIR /root/ ---> Using cache ---> f5d7f36bc37f Step 5/8 : RUN tar -xvf intel_virtual_gateway_console64_1_9_0.tar ---> Using cache ---> 6cab428f1bc2 Step 6/8 : RUN apt-get update && apt-get install -y expect expect-dev libxml2-utils ---> Using cache ---> 5bb1ee67332f
确认容器以root用户身份运行：
Step 7/8 : RUN whoami ---> Running in 112b87d77a08 root ---> 0c7eb38cc06b Removing intermediate container 112b87d77a08 Step 8/8 : RUN expect login.exp ---> Running in 5f186baf2f8d spawn ./virtualgatewayconsole_package/virtual_gateway_console_intel64 Install Error -------------------------------------------------------------------------------- To install the application, you must be a root user. -------------------------------------------------------------------------------- Type any key to exit: ^C
无法找出应用程序安装失败的原因，即使它以root用户身份运行。
编辑：添加login.exp脚本：这个脚本是如此基本，以完成我的function。
#cat login.exp #!/usr/bin/expect -f if 0 { *************************READ THIS BEFORE START********************* User password must consist of at least 3 of the following categories: uppercase, lowercase, numeric, and non-alphanumeric.

根目录的容器版本和主机上的根目录不一定是相同的东西。 最大的区别是，docker从root用户中删除了各种function，以防止它们突破容器，因此用户无法访问物理硬件设备，他们可以直接在容器中安装硬盘驱动器，或者调整cgroup设置来转义命名空间。
从您运行的文件的名称看来，您正在尝试安装需要访问硬件的KVM。 我不认为这将是一个容器的最佳用例，这个容器是为便携性和硬件隔离而devise的，而这个应用程序可能是用硬件特定的configuration和访问作为关键要求来devise的。
虽然docker build不允许硬件访问，你可能会使用docker run --privileged来手动执行安装，然后docker run --privileged docker commit将该容器保存到映像。 这通常是您想要构build图像的最后一种方式，但在这种情况下，它可能是唯一的方法，假设它是可能的。
