|
11 | 11 | The {ai-full} provides installation functionality as a service. This software-as-a-service (SaaS) approach has the following advantages:
|
12 | 12 |
|
13 | 13 | * *Web user interface:* The web user interface performs cluster installation without the user having to create the installation configuration files manually.
|
14 | 14 | * *No bootstrap node:* A bootstrap node is not required when installing with the {ai-full}. The bootstrapping process executes on a node within the cluster.
|
15 | 15 | * *Hosting:* The {ai-full} hosts:
|
16 |
| - - Ignition files |
17 |
| - - The installation configuration |
18 |
| - - A discovery ISO |
19 |
| - - The installer |
| 16 | +** Ignition files |
| 17 | +** The installation configuration |
| 18 | +** A discovery ISO |
| 19 | +** The installer |
20 | 20 | * *Streamlined installation workflow:* Deployment does not require in-depth knowledge of {product-title}. The {ai-full} provides reasonable defaults and provides the installer as a service, which:
|
21 |
| - - Eliminates the need to install and run the {product-title} installer locally. |
22 |
| - - Ensures the latest version of the installer up to the latest tested z-stream releases. Older versions remain available, if needed. |
23 |
| - - Enables building automation by using the API without the need to run the {product-title} installer locally. |
24 |
| -* *Advanced networking:* The {ai-full} supports IPv4 networking with SDN and OVN, IPv6 and dual stack networking with OVN only, NMState-based static IP addressing, and an HTTP/S proxy. OVN is the default Container Network Interface (CNI) for OpenShift Container Platform 4.12 and later releases, but you can use SDN. |
25 |
| - |
26 |
| -* *Preinstallation validation:* The {ai-full} validates the configuration before installation to ensure a high probability of success. Validation includes: |
27 |
| - - Ensuring network connectivity |
28 |
| - - Ensuring sufficient network bandwidth |
29 |
| - - Ensuring connectivity to the registry |
30 |
| - - Ensuring time synchronization between cluster nodes |
31 |
| - - Verifying that the cluster nodes meet the minimum hardware requirements |
32 |
| - - Validating the installation configuration parameters |

| 28 | +** Ensuring sufficient network bandwidth |
| 29 | +** Ensuring connectivity to the registry |
| 30 | +** Ensuring time synchronization between cluster nodes |
| 31 | +** Verifying that the cluster nodes meet the minimum hardware requirements |
| 32 | +** Validating the installation configuration parameters |
33 | 33 | * *REST API:* The {ai-full} has a REST API, enabling automation.
|

|
35 | 35 | The {ai-full} supports installing {product-title} on premises in a connected environment, including with an optional HTTP/S proxy. It can install the following:
|
36 | 36 |
|
37 |
| -* Highly available {product-title} or Single Node OpenShift (SNO) |
| 37 | +* Highly available {product-title} or {sno} (SNO) |
38 | 38 |
|
39 | 39 | * {product-title} on bare metal, Nutanix, or vSphere with full platform integration, or other virtualization platforms without integration
|
40 | 40 | * Optionally {VirtProductName} and {rh-storage} (formerly OpenShift Container Storage)
|
41 | 41 |
|
42 | 42 | The user interface provides an intuitive interactive workflow where automation does not exist or is not required. Users may also automate installations using the REST API.
