To install gitlab on a Rocky 8.x machine use:

1. Ensure proper DNS based resolution for desired FQDN.

   Installing gitlab using IP address will not work

2. Configure the desired FQDN to resolve to LAN IP via /etc/hosts
3. Upgrade the machine

   dnf -y upgrade

4. Configure ntp client via CentOS 8.x chronyc ntp client configuration
5. Create repository configuration file '/etc/yum.repos.d/gitlab_gitlab-ce.repo' with following contents:

   [gitlab_gitlab-ce]
   name=gitlab_gitlab-ce
   baseurl=https://packages.gitlab.com/gitlab/gitlab-ce/el/8/\$basearch
   repo_gpgcheck=1
   gpgcheck=1
   enabled=1
   gpgkey=https://packages.gitlab.com/gitlab/gitlab-ce/gpgkey
          https://packages.gitlab.com/gitlab/gitlab-ce/gpgkey/gitlab-gitlab-ce-3D645A26AB9FBD22.pub.gpg
   sslverify=1
   sslcacert=/etc/pki/tls/certs/ca-bundle.crt
   metadata_expire=300

6. Validate above repository is configured properly with

   dnf repolist

7. Install and enable postfix with:

   dnf -y install postfix
   systemctl enable postfix
   systemctl start postfix
   systemctl status postfix

8. Optionally if email should go via relay configure appropriate settings using CentOS 8.x postfix send email through relay or smarthost with smtp authentication
9. Install gitlab using configured repo via:

   EXTERNAL_URL="http://<fqdn-selected-for-repo>" dnf install -y gitlab-ce

10. Check initial root password in file '/etc/gitlab/initial_root_password'
11. Login at http://<fqdn> via root and observed password.
12. We can check installed gitlab version via:

    gitlab-rake gitlab:env:info
