3.5. Installing a cluster on Azure with network customizations
In OpenShift Container Platform version 4.5, you can install a cluster with a customized network configuration on infrastructure that the installation program provisions on Microsoft Azure. By customizing your network configuration, your cluster can coexist with existing IP address allocations in your environment and integrate with existing MTU and VXLAN configurations.
You must set most of the network configuration parameters during installation, and you can modify only kubeProxy configuration parameters in a running cluster.
3.5.1. 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.
