!!! warning "Document Under Construction"
    This document is very unfinished and should **NOT** be followed by anyone for deployment at this time.

**Purpose**: Deploying OpenStack via Ansible.

## Configure Hard-Coded DNS for Cluster Nodes
We want to ensure everything works even if the nodes have no internet access.  By hardcoding the FQDNs, this protects us against several possible stupid situations.

Run the following script to add the DNS entries.
```sh
# Make yourself root
sudo su
```

!!! note "Run `sudo su` Separately"
    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.

```sh
# Add the OpenStack node entries to /etc/hosts
echo "192.168.3.43 OPENSTACK-NODE-01.bunny-lab.io OPENSTACK-NODE-01" >> /etc/hosts
echo "192.168.3.44 OPENSTACK-NODE-02.bunny-lab.io OPENSTACK-NODE-02" >> /etc/hosts
echo "192.168.3.45 OPENSTACK-NODE-03.bunny-lab.io OPENSTACK-NODE-03" >> /etc/hosts
```

### Validate DNS Entries Added
```sh
cat /etc/hosts
```

!!! example "/etc/hosts Example Contents"
    When you run `cat /etc/hosts`, you should see output similar to the following:
    ```ini title="/etc/hosts"
    127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
    ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
    192.168.3.43 OPENSTACK-NODE-01.bunny-lab.io OPENSTACK-NODE-01
    192.168.3.44 OPENSTACK-NODE-02.bunny-lab.io OPENSTACK-NODE-02
    192.168.3.45 OPENSTACK-NODE-03.bunny-lab.io OPENSTACK-NODE-03
    ```

## 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"
```
