Mounted the .ssh folder into a docker container.
permissions on the host (ls -laHF):
total 40K
drwxr-xr-x 2 git git 4.0K Apr 7 21:27 ./
drwxr-xr-x 3 git git 4.0K Apr 7 21:20 ../
-rw------- 1 git git 2.7K Apr 7 21:27 authorized_keys

when i go to the mount in the container and do the same the owner changed:

drwxr-xr-x 5 git git 4.0K Dec 11 14:09 ../

the volumes are mounted with
services:
server:
volumes:
- /home/git/.ssh:/data/git/.ssh
Does anyone have any idea how that can be possible?
i have tried mounting the same folder into another container with
docker run -it -v /home/git/.ssh:/data/git/.ssh ubuntu:latest
This time all files are owned by nobody:nogroup (before it was nobody:nobody),
so the problem is not with the service inside the container
Found out my user (in this case git) wasn't in the docker group.
The group can be added with sudo usermod -aG docker git
