Thank you for installing GitLab!
GitLab was unable to detect a valid hostname for your instance.
Please configure a URL for your GitLab instance by setting `external_url`
configuration in /etc/gitlab/gitlab.rb file.
Then, you can start your GitLab instance by running the following command:
  sudo gitlab-ctl reconfigure

For a comprehensive list of configuration options please see the Omnibus GitLab readme
https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md

Help us improve the installation experience, let us know how we did with a 1 minute survey:

Notes:
Default admin account has been configured with following details:
Username: root
Password: You didn't opt-in to print initial root password to STDOUT.
Password stored to /etc/gitlab/initial_root_password. This file will be cleaned up in first reconfigure run after 24 hours.

NOTE: Because these credentials might be present in your log files in plain text, it is highly recommended to reset the password following https://docs.gitlab.com/ee/security/reset_user_password.html#reset-your-root-password.

# WARNING: This value is valid only in the following conditions
#          1. If provided manually (either via `GITLAB_ROOT_PASSWORD` environment variable or via `gitlab_rails['initial_root_password']` setting in `gitlab.rb`, it was provided before database was seeded for the first time (usually, the first reconfigure run).
#          2. Password hasn't been changed manually, either via UI or via command line.

#          If the password shown here doesn't work, you must reset the admin password following https://docs.gitlab.com/ee/security/reset_user_password.html#reset-your-root-password.
