Fix Gitlab Ansbile Role

The Ansible role GitHub - geerlingguy/ansible-role-gitlab: Ansible Role - GitLab  is not correct, not suitable for current version of GitLab 18.1

Change roles/external/geerlingguy.gitlab/templates/gitlab.rb.j2

# The directory where Git repositories will be stored.
# git_data_dirs({"default" => {"path" => "{{ gitlab_git_data_dir }}"} })
gitaly['configuration'] = {
  storage: [
    {
      name: 'default',
      path: '{{ gitlab_git_data_dir }}',
    },
  ],
}

Provision

Change root password

vagrant ssh $BOX -c "sudo cat /etc/gitlab/initial_root_password | grep Password:"

vagrant ssh $BOX -c "sudo cat /etc/gitlab/initial_root_password | grep Password:"
Password: L6CJP/AEZJTtyA45Hr72Q9gdj37lv9CdL+WOkkg/AqU=

Go to https://gitlab.c2platform.org  login as root with password retrieved with the command and change the password.
