When I ran `sudo su` and the echo commands below as one block of commands, it did not correctly write the changes to the `/etc/hosts` file. Just run `sudo su` by itself, then you can copy paste the codeblock below for all of the echo lines for each DNS entry.

## OpenStack Deployment Node
Assuming you deployed a Rocky Linux 9.5 VM with 120GB storage, 8-cores, and 8GB of RAM (these are overkill specs), you should run the following commands. [Original Deployment Documentation](https://docs.openstack.org/project-deploy-guide/openstack-ansible/latest/deploymenthost.html)
```sh
sudo su
dnf upgrade
dnf install -y git chrony openssh-server python3-devel sudo
dnf group install -y "Development Tools"
```
