hi,
i've installed OpenFoam as the site's guide say but when i run "./startOpenFoam+" the result is always the same:

"non-network local connections being added to access control list
Error response from daemon: linux spec user: Unable to find user <username>
Error: failed to start containers: of_v3.0_plus
You cannot attach to a stopped container, start it first"

How can i fix this? Thanx for the answers!

Try with new script .. i.e installOpenFOAM+
from site . It has been upgraded now to work with latest docker version 1.10 forward.
http://openfoam.com/download/install-binary.php

The error was coming because of latest docker version which is not supporting some argument as it was meant to be

Thanx, now it works, but when i run the script the bash shell come out like this:

non-network local connections being added to access control list
of_v3.0_plus
bash-4.1$

and the folder openFoam only exist in /opt when the start script is compilated. If i don't compile the start script it is as nothing was installed. So only when i'm in bash i can navigate with "cd' to the directory /opt/openFoam.
Is this normal?

yes this is normal. It is based on container technology i.e docker things. You have to be in bash shell started by ./startOpenFOAM+ script to work in OpenFOAM . Basically by running ./startOpenFOAM+ script , you are working inside container called of_v3.0_plus i.e the one created by ./installOpenFOAM+ scripts. Docker is an interesting technology, if you learn a bit about it , you will understand many things which is difficult to explain here

Wow i've read something about containers, it's awesome.

Last question.
It seems that the entire app (openfoam) is a container with all dependences. Doing so my os is still clear, docker and apps just use it, so if i need to uninstall openFoam i will just delete that container? I don't need to use stange "apt-get remove/autoremove/purge" that may leaves things inside the os.
Is this really true??

You are right partially... actual dependencies and software are there in OpenFOAM image. i.e if your run command "docker images" it will show you the base image of openfoam.
container are like working copy, you can delete it . If want complete removal , you need to delete base image by command docker rmi -f of_image (assuming of_image is image name).

So openfoam is the image that run in the container, i.e. the container is like a simplified os that can run openfoam in the same way developers did!

Sorry if i'm boring you and thanx for help...i will find time to study deeper and understand this technology

Hi Erman
The message is fine . You can work in terminal which has OpenFOAM environment set.

Thanks
Pawan
