attempt to automate things for gitpod clients

on gitpod client
for every user you want to give access (e.g. student)
create public/private keys
ssh-keygen -t rsa
you could automate it a bit like this:
ssh-keygen -t rsa -N "" -C "${USER}@${HOSTNAME}" -f ~/.ssh/id_rsa 
allow access to gitpod server 1
ssh-keyscan -H gitpod >> ~/.ssh/known_hosts
ssh-copy-id gitpod@gitpod
What about the password?
ssh gitpod@gitpod
sudo -i -u root sh -c 'cat /home/gitpod/.ssh/authorized_keys >> /home/gp/.ssh/authorized_keys'
sudo -i -u root sh -c 'ls -la /home/gp/.ssh/authorized_keys'
make sure that /home/gp/.ssh/authorized_keys has the right permissions:
-rw-rw-r-- 1 gp gp 821 May 27 17:06 /home/gp/.ssh/authorized_keys
on gitpod client
now you should be able to clone without a password e.g. as student
git clone gp@gitpod:u-boot.git
