Thu, 30 Nov 2023 10:00:00 -0400

Before deploying an ARO cluster, ensure you meet the following prerequisites:

Setup Tools

Install Azure CLI: Essential for managing Azure resources. Refer to the official documentation

Core Quota: Confirm availability of at least 40 cores to create and run an OpenShift Cluster.

RBAC Settings:
- Ensure you have Contributor and User Access Administrator roles on the cluster resource group.
- Assign Network Contributor role on the virtual network, if using a separate resource group.
- For stricter security policies, create a custom role with necessary permissions. Reference link.
Microsoft Entra (Former Azure AD):
- Have a member user of the tenant or a guest with Application administrator role for the tooling to create an application and service principal on your behalf for the cluster.
Terraform: If you plan to use Terraform for the deployment of the cluster, see here the required permissions.

Resource Provider:
- Register the Microsoft.RedHatOpenshift resource provider. Reference link.
Red Hat Integration:
- Obtain a Red Hat pull secret (Recommended for access to additional content like Operators and Container Registries).

This step is optional since you can use the built-in domain.
