Chapter 1. Ansible based deployment workflow
You can use Ansible to deploy Red Hat Hyperconverged Infrastructure for Virtualization on a single node or on 3 to 12 nodes.
The preparation of the inventory file based on the user requirements is a one time process and is created with the help of the example inventory files available.
The workflow for deploying RHHI for Virtualization using Ansible is as follows:
Install operating systems.
Modify firewall rules for additional software.
- (Optional) Modify firewall rules for disk encryption: Section 5.1, “Modifying firewall rules for disk encryption”.
Configure authentication between hyperconverged hosts.
Configure key-based SSH authentication without a password to enable automated configuration of the hosts: Configure key-based SSH authentication.
(Optional) Configure disk encryption.
- Define the details of your environment in inventory and playbook files: Defining deployment details
- Execute the Ansible playbook to deploy RHHI for Virtualization: Executing the deployment playbook
- Verify your deployment.
