1. What's the problem here?
2. Would it be possible to provide a better output (what is process 10) here?

Thanks.

seems like error is in ssh-keyscan command. If you run it inside pod, is there any error?

It checks /root/.ssh/known_hosts if host not in file, it will try to add key there but running command

ssh-keyscan -H git.example.org >> /root/.ssh/known_hosts

If that command can not complete then you may provide known_hosts file my mounting secret or configmap

I cannot exec into the pod because it is not running (because of the error)

I just tried to add our internal git-Server and also got errors.

I haven't a clue about ruby, so I can only help do debug what you tell me :)
