Permission denied during kit configuration about fhe-toolkit-linux HOT 3 CLOSED

I'm having the same issue. The docker container is not able to write any changes to the user's home directory.
Workaround 1 is to run the command with -s making the instance stateless. All computations stay only in the container and are therefore not persistent.

The problem is that the docker run command doesn't pass on the permissions correctly. This is what the ./RunToolkit.sh -p ubuntu call does:

docker run -d --name fhe-toolkit-ubuntu  -v /home/username/Documents/fhe-toolkit-linux/FHE-Toolkit-Workspace:/opt/IBM/FHE-Workspace  -p 8443:8443 ibmcom/fhe-toolkit-ubuntu

Ubuntu (also CentOS) puts default permissions of the FHE-Toolkit-Workspace repository to 755 which does not allow the container to write into the local FHE-Toolkit-Workspace folder.

Workaround 2: If I used chmod 777 FHE-Toolkit-Workspace, the Docker container is able to write into the local directory, making all computations persistent. That's quick and dirty.

Better would be to fix the ./RunToolkit.sh to pass on the permissions during the folder bind.

When running this on Linux we realize that there is a permissions issue on the persistent data space that is created on the user's local disk, FHE-Toolkit-Workspace directory. Because this is shared space between the local disk and the dockerimage, there is confusion on the docker side as to who the owner is.

It is a problem that we are working towards to find an ideal solution, but in the meantime there is a quick fix workaround.

To get pass the permission issue in the PersistData.sh file, at the end of the file, line 260 or beyond, add a change permission command to the directory such as this...

chmod -R 777 $PERSISTENT_FHE_WORKSPACE_PATH

This will allow the fhe user on the docker image to access and write to the necc. files to run the demos.

As an addition: I noted that MacOS is more forthcoming than Linux. When running the Linux toolkit (CentOS) in the terminal on my Mac, the command RunToolkit.sh -p centos triggers a pop-up window asking me to give permissions to let the container write to my Documents. On the other hand, CentOS and Ubuntu will take note of the issue but won't do anything about it.
