   2. Add the SSH keys of SysAdmins (your key if you can run the sys_admin role) to give root access.
4. Add a DNS record pointing to the server IP.
5. Configure the provisioning project:

1. Talk with the commission coordinator to update the contract if exists.
2. Remove the alerts and dashboards.
3. Remove the Prometheus job configuration related with this server.
4. Archive the repository in Gitlab or publish an MR deleting the host configuration in the provisioning repository.
5. Revoke the certificates:

$ sudo certbot certificates  # To check the certificates
...
$ sudo certbot revoke --cert-path /etc/letsencrypt/live/<domain-name>/cert.pem --key-path /etc/letsencrypt/live/<domain-name>/privkey.pem --reason cessationOfOperation  # Revocation reasons: https://en.wikipedia.org/wiki/Certificate_revocation_list#Reasons_for_revocation
