Hi Christopher,
The user is created to not run NEST inside the Docker image with root
privileges.
Additionally the user gets the user ID of the host system to allow a
smooth exchange of files.
As far as I know, Singularity and Sarus make sure that the user inside
the container is the same as the user outside the container. Everything
should work with that as well.
For a first test on PizDaint I also simply skipped the creation of the
user (even a bit more):

Hi all,
I have a question about nest user creation/usage in nest docker entrypoint file: I am
working with Sarus and Singularity and due to some permission limits I can't create a
new user inside a container. I have tried to modify the entrypoint.sh file as follows
https://github.com/ChristopherBignamini/nest-docker/blob/no_nest_user_creat…
in order to skip the creation of the nest user. I am not a nest expert but everything
seems to work, at least if I try to run a couple of examples like one_neuron.py and
twoneurons.py.
My question is: what is the reason behind the creation and usage of the nest user?
Thank you in advance.
Cheers
Christopher
