A stack is a Terraform configuration that you can use to provision and manage your OCI resources. To provision the resources defined in your stack, apply the configuration.

Choose the origin of the Terraform configuration. The Terraform configuration outlines the cloud resources to provision for this stack. Learn more
 My configuration

Upload Terraform configuration files.

 Template

Select an Oracle-provided template or private template.

 Source code control system

Select a Terraform configuration from Bitbucket Cloud, Bitbucket Server, DevOps, GitHub, or GitLab.

 Existing compartment

Create a stack that captures resources from the selected compartment (resource discovery).

Jobs | Oracle Cloud Infrastructure

Cluster Name
(Required) - The name of your OpenShift cluster. It should be the same as what was specified when creating the OpenShift ISO and it should be DNS compatible. The cluster_name value must be 1-54 characters. It can use lowercase alphanumeric characters or hyphen (-), but must start and end with a lowercase letter or a number.
This variable is required.

OpenShift Image Source URI
(Required) - The OCI Object Storage URI for the OpenShift image. Before provisioning resources through this Resource Manager stack, users should upload the OpenShift image to OCI Object Storage, create a pre-authenticated requests (PAR) uri, and paste the uri to this block. For more details, review Object Storage and PARs.
This variable is required.

Tag Namespace Compartment For OpenShift Resource Attribution Tags
(Required) - WARNING - Please make sure this tag exists before you apply the terraform stack. The compartment where the tag namespace for resource tags should be created. Defaults to current compartment. The tag namespace and defined tags for OpenShift Attribution on OCI resources will be `openshift-tags` and `openshift-resource`. If this namespace already exists, the field should be verified to ensure it is correctly defined and applied. Example --> "defined-tags" - {"openshift-tags"- {"openshift-resource" - "openshift-resource-infra"} }

Enable Public API Load Balancer
Create a Load Balancer for the OpenShift API endpoint (`api.<cluster>.<base_domain>`) in the public subnet with a public IP address. This allows users and administrators to access the OpenShift control plane over the internet. If disabled, the API Load Balancer will be created in a private subnet with a private IP, limiting access to within the VCN or through a connected VPN/private network. Public API access is useful for remote cluster management, automation, and CI/CD pipelines. In on-premise environments (e.g., C3/PCA), "public" IPs may refer to RFC 1918 addresses that are only routable within your internal network. Consult your network administrator to confirm external access.

Create Private DNS
Create a private DNS zone with your Base domain specified in Zone DNS. It will contain the same records as a public DNS zone and will facilitate the cluster's hostname resolution within the VCN. If using an unregistered domain name as the Base domain for your cluster, you should create a private DNS zone if possible, or you will have to take other measures to help the instances resolve the cluster's hostname. For more details, review Oracle Private DNS
