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.

## OpenStack Deployment Node ## OpenStack Deployment Node
The "Deployment" node / bootstrapper is responsible for running Ansible playbooks against the cluster nodes that will eventually be running OpenStack.

### Install Necessary Software
```sh ```sh
sudo su sudo su
dnf upgrade dnf upgrade
dnf install -y git chrony openssh-server python3-devel sudo dnf install -y git chrony openssh-server python3-devel sudo
dnf group install -y "Development Tools" dnf group install -y "Development Tools"
``` ```
### Configure SSH keys
Ansible uses SSH with public key authentication to connect the deployment host and target hosts. Run the following commands to configure this.
!!! warning "Do not run as root"
You want to make sure you run these commands as a normal user. (e.g. `nicole`).
``` sh
# Generate SSH Keys (Private / Public)
ssh-keygen
# Install Public Key on OpenStack Cluster/Target Nodes
ssh-copy-id -i /home/nicole/.ssh/id_rsa.pub nicole@openstack-node-01.bunny-lab.io
ssh-copy-id -i /home/nicole/.ssh/id_rsa.pub nicole@openstack-node-02.bunny-lab.io
ssh-copy-id -i /home/nicole/.ssh/id_rsa.pub nicole@openstack-node-03.bunny-lab.io
# Validate that SSH Authentication Works Successfully on Each Node
ssh nicole@openstack-node-01.bunny-lab.io
ssh nicole@openstack-node-02.bunny-lab.io
ssh nicole@openstack-node-03.bunny-lab.io
```
