3.4. Installing a cluster on Azure with customizations
In OpenShift Container Platform version 4.5, you can install a customized cluster on infrastructure that the installation program provisions on Microsoft Azure. To customize the installation, you modify parameters in the install-config.yaml file before you install the cluster.
3.4.1. Prerequisites
- Review details about the OpenShift Container Platform installation and update processes.
- Configure an Azure account to host the cluster and determine the tested and validated region to deploy the cluster to.
- If you use a firewall, you must configure it to allow the sites that your cluster requires access to.
- If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.
