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
# Add the OpenStack node entries to /etc/hosts
sudo su
echo "192.168.3.43 OPENSTACK-NODE-01.bunny-lab.io OPENSTACK-NODE-01" | sudo tee -a /etc/hosts
echo "192.168.3.44 OPENSTACK-NODE-02.bunny-lab.io OPENSTACK-NODE-02" | sudo tee -a /etc/hosts
echo "192.168.3.45 OPENSTACK-NODE-03.bunny-lab.io OPENSTACK-NODE-03" | sudo tee -a /etc/hosts
```
