Have no idea how to login
No instruction provided, admin / admin doesn't works.
Googled for some creds, but no luck.
Is that so difficult to put a short instruction how to login?
The initial login instructions should be presented in the installation output under the message "Thank you for installing GitLab!". Upon browsing to the login screen after installation, there should be a prompt to set an initial password. If not, a password for the root account can also be set via the Rails console, see https://docs.gitlab.com/ee/security/reset_user_password.html#rails-console Hope this helps!
