[Other] Having to reinstall Openfoam utilities inside docker after every log in

sohailr · April 19, 2017, 15:31

Dear all,

I am trying to install cfMesh. I am using a openfoam on debian with docker. I can install cfMesh and everything runs just fine. When I exit the docker however, my installed cfMesh utility is removed and I have to reinstall it every time I log into docker image.

Is there any way I can make the openfoam utilities I install permanent so I dont have to reinstall them after every log in?

Thanks

Sohail

Quick answer:

It may depend on the Docker image you are using and how it is configured to work.
What I mean is that many of the Docker images that have been configured to use OpenFOAM, have a mount option that mounts your own real home folder into the contained instance.
Therefore, if your home folder is mounted during boot up inside the contained instance, then the conventional installation steps for cfMesh and other custom software that is designed to work with OpenFOAM, should be installed at "~/OpenFOAM/your_username-OFversion/platforms", e.g.:
Code:
```
~/OpenFOAM/ofuser-4.1/platforms
```
I'm not familiar enough with Docker, so I suggest you search online for something like:
Code:
```
mount real home inside docker container
```

a)When you are running OpenFOAM from OpenCFD using docker then , changes will be there in docker container untill or unless you have deleted the container.
