= Creating {oci} infrastructure resources and services
|
|
|
|
You must create an {oci-distributed-no-rt} environment on your virtual machine (VM) or bare-metal shape. By creating this environment, you can install {product-title} and deploy a cluster on an infrastructure that supports a wide range of cloud options and strong security policies. Having prior knowledge of {oci-first-no-rt} components can help you with understanding the concept of {oci} resources and how you can configure them to meet your organizational needs.
|
|
|
|
The Agent-based Installer method for installing an {product-title} cluster on {oci-distributed-no-rt} requires that you manually create {oci} resources and services.
|
|
|
|
[IMPORTANT]
|
|
====
|
|
To ensure compatibility with {product-title}, you must set `A` as the record type for each DNS record and name records as follows:
|
|
|
|
* `api.<cluster_name>.<base_domain>`, which targets the `apiVIP` parameter of the API load balancer
|
|
* `api-int.<cluster_name>.<base_domain>`, which targets the `apiVIP` parameter of the API load balancer
|
|
* `*.apps.<cluster_name>.<base_domain>`, which targets the `ingressVIP` parameter of the Ingress load balancer
|
|
|
|
The `api.{asterisk}` and `api-int.{asterisk}` DNS records relate to control plane machines, so you must ensure that all nodes in your installed {product-title} cluster can access these DNS records.

.Prerequisites
|
|
|
|
* You configured an {oci} account to host the {product-title} cluster. See link:https://docs.oracle.com/iaas/Content/openshift-on-oci/install-prereq.htm[Prerequisites (Oracle documentation)].
|

|
|
.Procedure
|
