= Completing cluster configuration and initiating the installation
8+
9+
Before you can finally initiate the cluster installation, you must verify host details, configure cluster networking details, and download the default cluster credentials.
10+
11+
.Prerequisites
12+
13+
* You have booted all of the hosts that will comprise your cluster and configured them with the correct rendezvous node IP address.
14+
+
15+
[IMPORTANT]
16+
====
17+
You can add as many hosts as you want to your cluster.
18+
However, at this stage, you must at least have enough available hosts to match the value you specified in the *Number of control plane nodes* field of the installation console's *Cluster details* page.
19+
====
20+
21+
.Procedure
22+
23+
. On the installation console hosted by the rendezvous node, configure the hosts in the *Host discovery* page:
24+
25+
.. Verify that every machine you booted from the ISO image appears in the *Host Inventory* section and has a *Status* value of *Ready*.
26+
27+
.. For each host, click the expand icon and verify that all of the specification fields are correct.
28+
29+
.. Optional: For each host, configure the role by selecting an option from the dropdown menu of the *Role* column.
30+
The default value for every host except the rendezvous node is `Auto-assign`.
31+
32+
.. Click *Next* to continue.
33+
34+
. On the *Storage* page, click the expand icon for each host and verify that all of the specification fields are correct.
35+
36+
. Click *Next* to continue.
37+
38+
. Configure the cluster networking on the *Networking* page:
39+
40+
.. Optional: Select a machine network from the dropdown menu of the *Machine network* field.
41+
Otherwise, a default value is selected.
42+
43+
.. Enter an IP address in the *API IP* field.
44+
An API IP provides an endpoint for all users to interact with and configure the platform.
45+
46+
.. Enter an IP address in the *Ingress IP* field.
47+
An ingress IP provides an endpoint for application traffic flowing from outside the cluster.
48+
49+
.. Optional: Select the *Use advanced networking* checkbox and configure other parameters such as the *Cluster network CIDR*, the *Cluster network host prefix*, or *the Service network CIDR*.
50+
51+
.. Optional: Enter a key in the *Host SSH Public Key for troubleshooting after installation* field, which you can use to connect to hosts using a public SSH key for troubleshooting after installation.
52+
53+
.. Click *Next* to continue.
54+
55+
. On the *Download credentials* page, select the checkbox to acknowledge that you must download credential files prior to cluster installation.
56+
57+
. Click *Download credentials* and save the cluster credentials file in a secure location.
58+
+
59+
[IMPORTANT]
60+
====
61+
You must download the credentials at this stage.
62+
Once you initiate the cluster installation, the rendezvous node reboots and you can no longer retrieve the credentials.
63+
====
64+
65+
. On the *Review and create* page, review all of the cluster details and click *Install cluster* to initiate the cluster installation.

= Configuring cluster details and choosing Operators to install
8+
9+
Once the rendezvous node has been booted from the ISO image, configure details about your cluster and choose Virtualization Operators to install from the web console.
10+
11+
.Prerequisites
12+
13+
* You have the URL of the installation web console that was provided by the rendezvous node.
14+
15+
.Procedure
16+
17+
. In a web browser, go to the URL provided by the rendezvous node.
18+
19+
. Configure your cluster in the *Cluster details* page:
20+
21+
.. Enter a name for the cluster in the *Cluster name* field.
22+
23+
.. Enter a base domain for the cluster in the *Base domain* field.
24+
All subdomains for the cluster will use this base domain.
25+
+
26+
[NOTE]
27+
====
28+
The base domain must be a valid DNS name.
29+
You must not have a wildcard domain set up for the base domain.
30+
====
31+
32+
.. Enter your pull secret in the *Pull secret* field.
33+
You can obtain a copy of your pull secret link:https://console.redhat.com/openshift/install/pull-secret[here].
34+
35+
.. Optional: In the *Number of control plane nodes* field, select the number of control plane nodes for your installation from the dropdown menu.
36+
The default value is `3`.
37+
38+
.. Optional: Select the *include custom manifests* checkbox if you want to upload custom manifests to further configure your cluster.
39+
This option adds an additional page for custom manifests that you use later in the configuration process.
40+
+
41+
[IMPORTANT]
42+
====
43+
If you have already added custom manifests, clearing the *Include custom manifests* checkbox automatically deletes them all.
44+
You must confirm the deletion.
45+
====
46+
47+
.. Click *Next* to continue.
48+
Once you proceed to the next page, you cannot go back to change any of these cluster details.
49+
50+
. Choose additional Operators to install in the *Operators* page:
51+
52+
.. If you want to install all of the Operators recommended for running Virtualization on your cluster, select *Virtualization* in the *Bundles* section.
53+
54+
.. If you want to install only some Operators, select the individual Operators from the Single Operators section.
55+
+
56+
[NOTE]
57+
====
58+
Some of the listed Operators are available only as part of the Virtualization Operator bundle.
59+
====
60+
61+
.. Click *Next* to continue.

= Booting the remaining cluster hosts
8+
9+
After you have configured initial cluster details in the installation web console and have a defined cluster topology, you must boot the remaining machines that will make up your cluster from the ISO image.
10+
11+
[NOTE]
12+
====
13+
You can boot non-rendezvous node machines earlier in the installation process, even before you designate a machine as the rendezvous node. However, you must know the valid IP address that you will select for the rendezvous node.
14+
15+
When you boot your non-rendezvous node machines, the machines will perform a check to see if an Assisted Service is running at the specified rendezvous IP address.
16+
If the service is not yet running, a warning appears to confirm whether you would still like to proceed booting the machine from the ISO image.

26+
You can also boot from a USB drive containing the ISO image.
27+
28+
. Wait for a machine to boot from the image and display the *Rendezvous node setup* menu.
29+
30+
. Enter the rendezvous node IP address in the *Rendezvous node setup* menu and select *Save rendezvous IP*.
31+
32+
. Select *Save and Continue*.
33+
34+
. Repeat this process for each remaining machine that will comprise the hosts in your cluster.

= Mounting the ISO and booting the rendezvous node
8+
9+
To initiate the cluster installation, attach the downloaded ISO to the machine that will serve as your rendezvous host and boot the machine from the ISO.
10+
The rendezvous node runs as the bootstrap host during the installation, which hosts the configuration web console and runs an Assisted Service that facilitates the cluster deployment.
