4.7. Installing a cluster on GCP into an existing VPC
In OpenShift Container Platform version 4.5, you can install a cluster into an existing Virtual Private Cloud (VPC) on Google Cloud Platform (GCP). The installation program provisions the rest of the required infrastructure, which you can further customize. To customize the installation, you modify parameters in the install-config.yaml file before you install the cluster.
4.7.1. Prerequisites
- Review details about the OpenShift Container Platform installation and update processes.
- Configure a GCP account to host the cluster.
- 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.
