我正在使用以下脚本在docker容器中安装openFOAM：

Usage: ${0##*/} [OPTIONS]
options:
-d | -dir host directory mounted (defaults to current directory)
-x | -xhost use custom X authority and give container host network
-h | -help help
-p | -paraview include ParaView in the Docker image
Launches the OpenFOAM ${VER} Docker image.
- Requires installation of docker-engine.
- Runs a "containerized" bash shell environment where the user can run OpenFOAM
and, optionally, ParaView (see below).
- The container mounts the user's file system so that case files are stored
permanently. The container mounts the current directory by default, but the
user can also specify a particular directory using the "-d" option.
- Mounting the user's HOME directory is disallowed.
- The '-xhost' option is useful when accessing the host via 'ssh -X'.
This option should only be used when strictly necessary, as it relies on the
option '--net=host' when launching the container in Docker, which will
give to the container full access to the Docker host network stack and
potentially the host's system services that rely on network communication,
making it potentially insecure.
ParaView:
Graphical applications from the Docker container require installation of the
Xquartz X server to display on the host machine. While applications such as
Gedit, Emacs and GnuPlot will run effectively using Xquartz, more intensive
OpenGL applications, in particular ParaView, can be prohibitively slow.
Therefore, the default Docker image does not contain ParaView and users can
instead install ParaView directly from the vendor and use the built-in reader
module for OpenFOAM: http://www.paraview.org/download
However, if the user wishes to include ParaView with the official OpenFOAM
reader module in their Docker container, they can do so with the "-p" option.
Example:
To store data in ${HOME}/OpenFOAM/${USER}-${VER}, the user can launch
${Script} either by:
cd ${HOME}/OpenFOAM/${USER}-${VER} && ${Script}
or
${Script} -d ${HOME}/OpenFOAM/${USER}-${VER}
Further Information:
http://openfoam.org/download/8-macos
Note:
The container user name appears as "openfoam" but it is just an alias.

这将创建一个用户"ofuser"。为什么？一旦我运行了上面的脚本，然后
xhost +local:of_v2006
docker start of_v2006
docker attach of_v2006
我最终在码头上：
[ofuser@3032b6018d82 woo]$ whoami
ofuser
I follow instructions to do a simulation and it creates files that are supposed to be available from the mac os itself, i.e. outside the docker container, but they seem to be in locations like /home/ofuser/...../ofuser/run/..., which don't seem to exist outside the container. Part of output:
[ofuser@5b3db0ac969b woo]$ mkdir $FOAM_RUN
mkdir: cannot create directory '/home/ofuser/OpenFOAM/ofuser-v2006/run': No such file or directory
所以，我如何让用户"泡沫"或"呼"而不是用户。那个用户是怎么来的？我如何将workDir设置为/Users/woo/Containers/foam？我必须在设置中使用/tmp/.X11unix吗？显示器无法连接到我设置的XQuartz显示器等。
我正在运行相同的设置，是的，这是可能的。我也花了一些时间来运行它，但我想我可以澄清一些事情。
首先是关于目录的问题。这可以在dockerfile中设置。提供的默认dockerfile对我来说也不够。请参阅以下摘录：
"Mounts": [
...
{
"Type": "bind",
"Source": "/home/*****/OpenFOAM/run",
"Destination": "/home/openfoam",
"Mode": "Z",
"RW": true,
"Propagation": "rprivate"
},
......
这绑定了"；来源">-在您的机器上-使用"strong>"；目的地"容器中的目录。对我来说，关键的选择是"；Z"；默认docker文件中不存在的标志。
X11的设置还取决于"；Z"；标志，并且可以/应该在那里设置。我不完全确定你的实际设置，但这对我来说很好。
"Mounts": [
...
{
"Type": "bind",
"Source": "/tmp/.X11-unix",
"Destination": "/tmp/.X11-unix",
"Mode": "Z",
"RW": true,
"Propagation": "rprivate"
},
......
关于新添加的用户，我自己仍然不知道背后的原因，但我可以告诉你，我必须使用第二个用户，它运行良好。通常情况下，您只使用此用户登录到容器，而不使用其他用户。在Linux下，执行这些步骤并验证新用户是否在docker用户组中
$ sudo groupadd docker
$ sudo usermod -aG docker <user>
$ sudo groups <user>
